Add support for entering emoji by name

This commit adds some basic support for entering emoji by name
to GtkIMContextSimple. We respect the input-purpose property and
only support emoji in free-form fields.

To begin an emoji sequence, use Ctrl-Shift-e instead of Ctrl-Shift-u
that is used for hex input. Otherwise, the behavior is the same:
you can can let go of the modifier keys and end the sequence with
space or enter, or hold on to the modifier keys and end the sequence
by releasing them.

Only a limited, fixed set of names is supported:

-# Contribution guidelines
-
-Thank you for considering contributing to the GTK project!
-
-These guidelines are meant for new contributors, regardless of their level
-of proficiency; following them allows the maintainers of the GTK project to
-more effectively evaluate your contribution, and provide prompt feedback to
-you. Additionally, by following these guidelines you clearly communicate
-that you respect the time and effort that the people developing GTK put into
-managing the project.
-
-GTK is a complex free software GUI toolkit, and it would not exist without
-contributions from the free and open source software community. There are
-many things that we value:
-
- - bug reporting and fixing
- - documentation and examples
- - tests
- - new features
-
-Please, do not use the issue tracker for support questions. If you have
-questions on how to use GTK effectively, you can use:
-
- - the `#gtk` IRC channel on irc.gnome.org
- - the [gtk](https://mail.gnome.org/mailman/listinfo/gtk-list) mailing list,
-   for general questions on GTK
- - the [gtk-app-devel](https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list)
-   mailing list, for questions on application development with GTK
- - the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
-   mailing list, for questions on developing GTK itself
-
-You can also look at the GTK tag on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/gtk).
-
-The issue tracker is meant to be used for actionable issues only.
-
-## How to report bugs
-
-### Security issues
-
-You should not open a new issue for security related questions.
-
-When in doubt, send an email to the [security](mailto:security@gnome.org)
-mailing list.
-
-### Bug reports
-
-If you're reporting a bug make sure to list:
-
- 0. which version of GTK are you using?
- 0. which operating system are you using?
- 0. the necessary steps to reproduce the issue
- 0. the expected outcome
- 0. a description of the behavior; screenshots are also welcome
- 0. a small, self-contained example exhibiting the behavior; if this
-    is not available, try reproducing the issue using the GTK examples
-    or interactive tests
-
-If the issue includes a crash, you should also include:
-
- 0. the eventual warnings printed on the terminal
- 0. a backtrace, obtained with tools such as GDB or LLDB
-
-For small issues, such as:
-
- - spelling/grammar fixes in the documentation
- - typo correction
- - comment clean ups
- - changes to metadata files (CI, `.gitignore`)
- - build system changes
- - source tree clean ups and reorganizations
-
-You should directly open a merge request instead of filing a new issue.
-
-### Features and enhancements
-
-Feature discussion can be open ended and require high bandwidth channels; if
-you are proposing a new feature on the issue tracker, make sure to make
-an actionable proposal, and list:
-
- 0. what you're trying to achieve
- 0. prior art, in other toolkits or applications
- 0. design and theming changes
-
-If you're proposing the integration of new features it helps to have
-multiple applications using shared or similar code, especially if they have
-iterated over it various times.
-
-Each feature should also come fully documented, and with tests.
-
-## Your first contribution
-
-### Prerequisites
-
-If you want to contribute to the GTK project, you will need to have the
-development tools appropriate for your operating system, including:
-
- - Python 3.x
- - Meson
- - Ninja
- - Gettext (19.7 or newer)
- - a [C99 compatible compiler](https://wiki.gnome.org/Projects/GLib/CompilerRequirements)
-
-Up-to-date instructions about developing GNOME applications and libraries
-can be found on [the GNOME Developer Center](https://developer.gnome.org).
-
-The GTK project uses GitLab for code hosting and for tracking issues. More
-information about using GitLab can be found [on the GNOME
-wiki](https://wiki.gnome.org/GitLab).
-
-### Dependencies
-
-In order to get GTK from Git installed on your system, you need to have the
-required versions of all the software dependencies required by GTK; typically,
-this means a recent version of GLib, Cairo, Pango, and ATK, as well as the
-platform-specific dependencies for the windowing system you are using (Wayland,
-X11, Windows, or macOS).
-
-The core dependencies for GTK are:
-
- - [GLib, GObject, and GIO](https://gitlab.gnome.org/GNOME/glib)
- - [Cairo](http://cairographics.org)
- - [Pango](https://gitlab.gnome.org/GNOME/pango)
- - [GdkPixbuf](https://gitlab.gnome.org/GNOME/gdk-pixbuf)
- - [Epoxy](https://github.com/anholt/libepoxy)
- - [ATK](https://gitlab.gnome.org/GNOME/atk)
- - [Graphene](https://github.com/ebassi/graphene)
-
-GTK will attempt to download and build some of these dependencies if it
-cannot find them on your system.
-
-Additionally, you may want to look at projects that create a development
-environment for you, like [jhbuild](https://wiki.gnome.org/HowDoI/Jhbuild)
-and [gvsbuild](https://github.com/wingtk/gvsbuild).
-
-### Getting started
-
-You should start by forking the GTK repository from the GitLab web UI, and
-cloning from your fork:
-
-```sh
-$ git clone https://gitlab.gnome.org/yourusername/gtk.git
-$ cd gtk
-```
-
-**Note**: if you plan to push changes to back to the main repository and
-have a GNOME account, you can skip the fork, and use the following instead:
-
-```sh
-$ git clone git@gitlab.gnome.org:GNOME/gtk.git
-$ cd gtk
-```
-
-To compile the Git version of GTK on your system, you will need to
-configure your build using Meson:
-
-```sh
-$ meson _builddir .
-$ cd _builddir
-$ ninja
-```
-
-Typically, you should work on your own branch:
-
-```sh
-$ git checkout -b your-branch
-```
-
-Once you've finished working on the bug fix or feature, push the branch
-to the Git repository and open a new merge request, to let the GTK
-maintainers review your contribution.
-
-### Code reviews
-
-Each contribution is reviewed by the core developers of the GTK project.
-
-The [CODEOWNERS](./docs/CODEOWNERS) document contains the list of core
-contributors to GTK and the areas for which they are responsible; you
-should ensure to receive their review and signoff on your changes.
-
-### Commit messages
-
-The expected format for git commit messages is as follows:
-
-```plain
-Short explanation of the commit
-
-Longer explanation explaining exactly what's changed, whether any
-external or private interfaces changed, what bugs were fixed (with bug
-tracker reference if applicable) and so forth. Be concise but not too
-brief.
-
-Closes #1234
-```
-
- - Always add a brief description of the commit to the _first_ line of
- the commit and terminate by two newlines (it will work without the
- second newline, but that is not nice for the interfaces).
-
- - First line (the brief description) must only be one sentence and
- should start with a capital letter unless it starts with a lowercase
- symbol or identifier. Don't use a trailing period either. Don't exceed
- 72 characters.
-
- - The main description (the body) is normal prose and should use normal
- punctuation and capital letters where appropriate. Consider the commit
- message as an email sent to the developers (or yourself, six months
- down the line) detailing **why** you changed something. There's no need
- to specify the **how**: the changes can be inlined.
-
- - When committing code on behalf of others use the `--author` option, e.g.
- `git commit -a --author "Joe Coder <joe@coder.org>"` and `--signoff`.
-
- - If your commit is addressing an issue, use the
- [GitLab syntax](https://docs.gitlab.com/ce/user/project/issues/automatic_issue_closing.html)
- to automatically close the issue when merging the commit with the upstream
- repository:
-
-```plain
-Closes #1234
-Fixes #1234
-Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1234
-```
-
- - If you have a merge request with multiple commits and none of them
- completely fixes an issue, you should add a reference to the issue in
- the commit message, e.g. `Bug: #1234`, and use the automatic issue
- closing syntax in the description of the merge request.
-
-### Commit access to the GTK repository
-
-GTK is part of the GNOME infrastructure. At the current time, any
-person with write access to the GNOME repository can merge changes to
-GTK. This is a good thing, in that it encourages many people to work
-on GTK, and progress can be made quickly. However, GTK is a fairly
-large and complicated project on which many other things depend, so to
-avoid unnecessary breakage, and to take advantage of the knowledge
-about GTK that has been built up over the years, we'd like to ask
-people committing to GTK to follow a few rules:
-
-0. Ask first. If your changes are major, or could possibly break existing
-   code, you should always ask. If your change is minor and you've been
-   working on GTK for a while it probably isn't necessary to ask. But when
-   in doubt, ask. Even if your change is correct, somebody may know a
-   better way to do things. If you are making changes to GTK, you should
-   be subscribed to the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
-   mailing list; this is a good place to ask about intended changes.
-   The `#gtk` IRC channel on irc.gnome.org is also a good place to find GTK
-   developers to discuss changes, but if you live outside of the EU/US time
-   zones, an email to the gtk-devel mailing list is the most certain and
-   preferred method.
-
-0. Ask _first_.
-
-0. Always write a meaningful commit message. Changes without a sufficient
-   commit message will be reverted.
-
-0. Never push to the `master` branch, or any stable branches, directly; you
-   should always go through a merge request, to ensure that the code is
-   tested on the CI infrastructure at the very least. A merge request is
-   also the proper place to get a comprehensive code review from the core
-   developers of GTK.
-
-If you have been contributing to GTK for a while and you don't have commit
-access to the repository, you may ask to obtain it following the [GNOME account
-process](https://wiki.gnome.org/AccountsTeam/NewAccounts).

+Up-to-date instructions about developing GNOME applications and libraries
+can be found here:
+
+        http://library.gnome.org/devel/
+
+Information about using git with GNOME can be found here:
+
+        https://wiki.gnome.org/Git
+
+In order to get GIT GTK+ installed on your system, you need to have
+the most recent GIT versions of GLib, Pango, and ATK installed as well.
+The installation process of these libraries is similar to that of GTK+,
+but needs to be fulfilled prior to installation of GTK+.
+
+If at all possible, please use GIT to get the latest development version of
+gtk+ and glib. You can do the following to get glib and gtk+ from GIT:
+
+        $ git clone git://git.gnome.org/glib
+        $ git clone git://git.gnome.org/pango
+        $ git clone git://git.gnome.org/atk
+        $ git clone git://git.gnome.org/gtk+
+
+Note: if you plan to push changes to back to the master repository and
+have a gnome account, you want to use the following instead:
+
+        $ git clone ssh://<username>@git.gnome.org/git/gtk+
+
+To compile the GIT version of GTK+ on your system, you will need to take
+several steps to setup the tree for compilation.  You can do all these
+steps at once by running:
+
+        gtk+$ ./autogen.sh
+
+Basically this does the following for you:
+
+        gtk+$ aclocal; automake; autoconf
+
+The above commands create the `configure' script.  Now you
+run the `configure' script in `gtk+/' to create all Makefiles.
+More information about that in `INSTALL'.
+
+Before running `autogen.sh' or `configure', make sure you have libtool
+in your path.
+
+Note that autogen.sh runs configure for you.  If you wish to pass
+options like `--prefix=/usr' to `configure' you can give those options
+to `autogen.sh' and they will be passed on to `configure'.
+
+For information about submitting patches and pushing changes
+to GIT, see the `README' and `README.commits' files. In particular,
+don't, under any circumstances, push anything to GIT before
+reading and understanding `README.commmits'.

+Prerequisites
+=============
+
+GTK+ requires the following packages:
+
+ - The GLib, Pango, GdkPixbuf, ATK and cairo libraries, available at
+   the same location as GTK+. GTK+ @GTK_VERSION@ requires at least
+   GLib @GLIB_REQUIRED_VERSION@, Pango @PANGO_REQUIRED_VERSION@,
+   GdkPixbuf @GDK_PIXBUF_REQUIRED_VERSION@, ATK @ATK_REQUIRED_VERSION@
+   and cairo @CAIRO_REQUIRED_VERSION@.
+
+ - libepoxy, for cross-platform OpenGL support.
+   It can be found here: https://github.com/anholt/libepoxy
+
+ - Each GDK backend has its own backend-specific requirements. For
+   the X11 backend, X11 R6 and XInput version 2 (as well as a number
+   of other extensions) are required. The Wayland backend requires
+   (obviously) the Wayland libraries.
+
+ - gobject-introspection @INTROSPECTION_REQUIRED_VERSION@ or newer.
+
+Simple install procedure
+========================
+
+  % tar xf gtk+-@GTK_VERSION@.tar.xz          # unpack the sources
+  % cd gtk+-@GTK_VERSION@                     # change to the toplevel directory
+  % ./configure                        # run the `configure' script
+  % make                               # build GTK+
+  [ Become root if necessary ]
+  % make install                       # install GTK+
+
+The Details
+===========
+
+Complete information about installing GTK+ and related libraries
+can be found in the file:

-
-Overview of Changes in GTK+ 1.3.1:
-
-* GTK+ now uses the Pango library for text manipulation. All
-  strings in GTK+ now are in Unicode, languages written
-  from right-to-left, and complex-text languages are now supported.
-* The gdk-pixbuf library for image loading and manipulation is 
-  has been integrated with GTK+.
-* The GTK+ object system has mostly been moved to GLib, separating
-  it from the GUI code. Many significant enhancements have been
-  made as part of this.
-* A new text widget is now included. This started as a port
-  of the Tk text widget, and includes such features of the Tk
-  text widget as tags, marks, and unicode text support. It
-  has been enhanced to support model-view operation and the
-  full power of Pango.
-* The GDK library has been extensively revised to support multiple
-  windowing systems. The only fully functional backend in 1.3.1
-  is the X11 backend, however, ports to Win32, Linux-framebuffer,
-  Nano-X, BeOS, and MacOS exist in various states of completion,
-  and at least some of these will be finished and integrated in 
-  before the final GTK+-2.0 release.
-* 32-bit coordinates are now supported throughout GDK and GTK+
-  (they are emulated where not supported by the windowing system.)
-* Many minor bug fixes and enhancements. Incompatible changes
-  are documented in docs/Changes-2.0.txt
-
-Overview of Changes in GTK+ 1.2.8:
-
-* GNU Make 3.79 bug workaround

-  HScale, VScale, Pixmap, Viewport, OptionMenu, Entry and Notebook.
-* Upgrade to libtool 1.3.4.
-
-Overview of Changes in GTK+ 1.2.6:
-
-* container queue_resize fixes
-* gtk[vh]scale: minor fixups
-* rename idle to idle_id in testgtk to avoid conflicts with 
-  broken libs
-* More consistent naming of gtkrc files
-* Added language support: ro, uk
-
-Overview of Changes in GTK+ 1.2.5:
-
-* more GtkCTree and GtkWindow bug fixes.
-* more redraw/resize queue fixes, better expose event
-  discarding code.
-* more miscellaneous bugs fixed
-* new configure.in option --disable-rebuilds to completely disable
-  rebuilds of autogenerated sources.
-* check for 5.002 now, to avoid failing autogeneration build rules due
-  to old perl versions.
-* fonts (and fontsets) are cached now.
-* more autogeneration make rules and dependency fixups, we should be
-  save with autogeneration up to make -j12 now ;)
-* new window position GTK_WIN_POS_CENTER_ALWAYS, which will recenter the
-  GtkWindow on every size change.
-* major rework of window manager hints handling code, fixed a bunch of
-  races with the new resizing code.
-* the new wm hints and resizing code is absolutely perfect and bug free now,
-  it only lacks testing ;)
-* fixed up various rc style memory problems.
-* gtk_widget_modify_style() now properly changes the style of realized widgets
-  and references the style passed into it. if people worked around this bug,
-  this will introduce a slight memory leak in their code.
-  The code should typically look like:
-            GtkRcStyle *rc_style = gtk_rc_style_new ();
-            [...]
-            gtk_widget_modify_style (widget, rc_style);
-            gtk_rc_style_unref (rc_style);
-* fix problems with positioning menus offscreen.
-* GtkText fixes for some crashes and drawing errors.
-* Better handling for unexpected window destroys in GDK and GTK+.
-  This should make it possible to use a GtkPlug and catch the
-  case where its parent socket is randomly killed.
-* FAQ updates.
-* FileSelection i18n patches, RadioButton fixups.
-* many translation improvements.
-* miscellaneous other bugs fixed.

-* Fixed mapping for GdkInputCondition<->GIOCondition, this should fix
-  problems where closed pipes were no longer signaling GDK_INPUT_READ on
-  systems with a native poll().
-* Some cleanups to GtkLabel's memory allocation code (shouldn't leak memory
-  anymore).
-* We don't attempt to lookup xpm color "None" anymore, this should prevent
-  eXodus (commercial X windows server) from popping up a color dialog every
-  time a transparent pixmap is created.
-* Fixed bug where Gtk timeout/idle handlers would execute without the global
-  Gdk lock being held.
-* Other minor bug fixes.
-
-Overview of Changes in GTK+ 1.2.1:
-
-* Many Bug fixes have been applied to the menu and accelerator code.
-* GtkItemFactory can "adopt" foreign menu items now and manage their
-  accelerator installation. This is often required to get GtkItemFactory
-  like accelerator propagation between different windows with the same
-  menu hierarchy and for centralized parsing and saving of accelerators.
-* GtkCList/GtkCTree buttons should always display correctly now.
-* Miscellaneous other bug fixes.
-

-* DND fixes for 64 bit architectures, and for specifying operations 
-  with modifier keys.
-* Major revisions to GtkLayout: avoid having to create window
-  for NO_WINDOW children, adjust allocations of children as 
-  scrolled so queued draws work, and a resize is queued instead
-  of allocating directly in a put() or move()
-
-What is new in GTK+ 1.1.13:
-
-* Dnd and selection bug fixes and memory purification.
-* Widget sensitivity fixups.
-* Tooltips windows are now named "gtk-tooltips" so rc file rules
-  can match tooltips windows. Fixed interaction of tooltips and NO_WINDOW
-  widgets.
-* Spin buttons now update their values upon value retrieval.

-  expose event generation.
-* Gdk event queue fixups, this solves the double-click problems people were

-* Improvements to Gdk color handling so we greatly reduce server traffic and
-  don't leak colors anymore.
-* Improved internal widget tree iterators (the GtkContainer::foreach signal
-  vanished because of this).
-* Option menus can have the keyboard focus now.
-* More fixups to the text widget.
-* GtkFileSelection should behave much more nicely in combination with AFS now.
-* Support for label underlining.
-* Support for GLib 1.1.3 log domains.
-* Documentation improvements.
-* Configuration fixes on various platforms.
-* Miscellaneous fixes to XInput support.
-* Build with shared library dependencies on Linux
-* Fix for a major bug in the type systems memory allocation code that could
-  cause random crashes.
-* Libtool update to version 1.2b.
-* Lots of bugfixes and cleanups again ;)
-
-
-What is new in GTK+ 1.1.1:
-
-* Tutorial updates and additions.
-* Key binding support for GtkListItems and GtkList.
-* Extended selection mode and autoscrolling for GtkLists.
-* A GtkCtree now operates on GtkCTreeNode* structures rather than GList*.
-* GtkCTreeNodes can now be created from GNode trees.
-* Bug fixes for GtkNotebook, GtkCList, GtkCombo and GdkWindow reparentation.
-
-
-What is new in GTK+ 1.1.0:
-
-* New widget GtkFontSelector.
-* New featureful progress bar.
-* New container widget GtkPacker.
-* New object GtkItemFactory, GtkMenuFactory is deprecated.
-* New key binding system, configurable via rcfiles, similar to styles.
-* New widget GtkCTree with drag selections and keyboard movement and
-  and horizontal scrolling. Features also implemented for GtkCList.
-* Significant speedups to widget creation and destruction through caching
-  colormap and visual queries to the XServer.
-* Speedups for type creation and especially gtk_type_is_a() checks.
-* Speedups in signal lookup, creation and emissions and connection handling.
-* Minor speedups with object data allocation and destruction.
-* Additions to the signal handling API (e.g. *_emitv).
-* Support for rc-file reparsing.
-* Resizing logic is now implemented on container widget basis, rather than
-  for toplevel GtkWindows only.
-* Buttons support relief styles now.
-* Some widgets are now allocated through memchunks to behave more memory wise.
-* Newly included file gtkfeatures.h which defines compatibility macros to
-  test for certain API features upon program compilation.
-* Child arguments support for container widgets.
-* Far better support for object arguments, revamp of the underlying
-  mechanism for speed and reusability. Child/object arguments don't
-  need to be preceded by the "GtkType::" portion anymore.
-* Removed GtkAcceleratorTable in favour of GtkAccelGroup, accelerator display
-  is now performed by a new widget GtkAccelLabel.
-* Overhaul of the resizing code. Resizing behaviour can now be specified
-  on GtkContainer basis, so the underlying algorithm isn't only available
-  for GtkWindows.
-* GtkTables are now fully resizable.
-* The GtkType system now supports an additional base class initialization
-  function.
-* GtkStyles and key bindings can now be looked up depending on the base
-  types of a widget, through a new keyword `class' in rc files.
-* GtkButton derives from GtkBin (finally).  
-* More descriptive error messages on rc parsing.  
-* Runtime information is available to query enum/flag definition values.
-* Upgrade to libtool-1.2
-* Legions of bug fixes, memory leaks, segfaults, of-by-something errors...
-  including those that already went into the 1.0.x branch.
-* A big bunch of features and cosmetic fixups that just got lost in
-  the masses of changesonfigure problem when cross-compiling

+GTK+ is part of the GNOME git repository. At the current time, any
+person with write access to the GNOME repository, can make changes to
+GTK+. This is a good thing, in that it encourages many people to work
+on GTK+, and progress can be made quickly. However, GTK+ is a fairly
+large and complicated package that many other things depend on, so to
+avoid unnecessary breakage, and to take advantage of the knowledge
+about GTK+ that has been built up over the years, we'd like to ask
+people committing to GTK+ to follow a few rules:
+
+0) Ask first. If your changes are major, or could possibly break existing
+   code, you should always ask. If your change is minor and you've
+   been working on GTK+ for a while it probably isn't necessary
+   to ask. But when in doubt, ask. Even if your change is correct,
+   somebody may know a better way to do things.
+
+   If you are making changes to GTK+, you should be subscribed
+   to gtk-devel-list@gnome.org. (Subscription address:
+   gtk-devel-list-request@gnome.org.) This is a good place to ask
+   about intended changes.
+
+   #gtk+ on GIMPNet (irc.gimp.org, irc.us.gimp.org, irc.eu.gimp.org, ...)
+   is also a good place to find GTK+ developers to discuss changes with,
+   however, email to gtk-devel-list is the most certain and preferred
+   method.
+
+1) Ask _first_.
+
+2) With git, we no longer maintain a ChangeLog file, but you are expected
+   to produce a meaningful commit message. Changes without a sufficient
+   commit message will be reverted. See below for the expected format
+   of commit messages.
+
+Notes:
+
+* When developing larger features or complicated bug fixes, it is
+  advisable to work in a branch in your own cloned GTK+ repository.
+  You may even consider making your repository publically available
+  so that others can easily test and review your changes.
+
+* The expected format for git commit messages is as follows:
+
+=== begin example commit ===
+Short explanation of the commit
+
+Longer explanation explaining exactly what's changed, whether any
+external or private interfaces changed, what bugs were fixed (with bug
+tracker reference if applicable) and so forth. Be concise but not too brief.
+=== end example commit ===
+
+  - Always add a brief description of the commit to the _first_ line of
+    the commit and terminate by two newlines (it will work without the
+    second newline, but that is not nice for the interfaces).
+
+  - First line (the brief description) must only be one sentence and
+    should start with a capital letter unless it starts with a lowercase
+    symbol or identifier. Don't use a trailing period either. Don't exceed
+    72 characters.
+
+  - The main description (the body) is normal prose and should use normal
+    punctuation and capital letters where appropriate. Normally, for patches
+    sent to a mailing list it's copied from there.
+
+  - When committing code on behalf of others use the --author option, e.g.
+    git commit -a --author "Joe Coder <joe@coder.org>" and --signoff.

+The Win32 backend in GTK+ is not as stable or correct as the X11 one.
+
+For prebuilt runtime and developer packages see
+http://ftp.gnome.org/pub/gnome/binaries/win32/
+
+Building GTK+ on Win32
+======================
+
+First you obviously need developer packages for the compile-time
+dependencies: GDK-Pixbuf, Pango, atk, glib, gettext-runtime, libiconv at least.
+See http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies .
+
+For people compiling GTK+ with Visual C++ 2005 or later, it is
+recommended that the same compiler is used for at least GDK-Pixbuf,
+Pango, atk and glib so that crashes and errors caused by different CRTs
+can be avoided.  The VS 2008 project files and/or VS Makefiles are
+either already available or will be available in the next stable release.
+Unfortunately compiling with Microsoft's compilers versions 2003 or earlier
+is not supported as compiling the latest stable GLib (which *is* required for
+building this GTK+ release) requires features from newer compilers
+and/or Platform SDKs
+
+After installing the dependencies, there are two ways to build GTK+
+for win32.
+
+1) GNU tools, ./configure && make install
+-----------------------------------------
+
+This requires you have mingw and MSYS.
+
+Use the configure script, and the resulting Makefiles (which use
+libtool and gcc to do the compilation). I use this myself, but it can
+be hard to setup correctly.
+
+The full script I run to build GTK+ 2.16 unpacked from a source
+distribution is as below. This is from bulding GTK+ 2.16.5. I don't
+use any script like this to build the development branch, as I don't
+distribute any binaries from development branches.
+
+# This is a shell script that calls functions and scripts from
+# tml@iki.fi's personal work env<6E>ronment. It is not expected to be
+# usable unmodified by others, and is included only for reference.

+
+You should not just copy the above blindly. There are some things in
+the script that are very specific to *my* build setup on *my* current
+machine. For instance the "latest" command, the "usedev" and
+"usemsvs6" shell functions, the /devel/dist folder. The above script
+is really just meant for reference, to give an idea. You really need
+to understand what things like PKG_CONFIG_PATH are and set them up
+properly after installing the dependencies before building GTK+.
+
+As you see above, after running configure, one can just say "make
+install", like on Unix. A post-build fix is needed, running
+gdk-pixbuf-query-loaders once more to get a correct gdk-pixbuf.loaders
+file.
+
+For a 64-bit build you need to remove the gtk/gtk.def file and let it
+be regenerated by the makefilery. This is because the 64-bit GTK dll
+has a slightly different list of exported function names. This is on
+purpose and not a bug. The API is the same at the source level, and
+the same #defines of some function names to actually have a _utf8
+suffix is used (just to keep the header simpler). But the
+corresponding non-suffixed function to maintain ABI stability are not
+needed in the 64-bit case (because there are no older EXEs around that
+would require such for ABI stability).
+
+
+2) Microsoft's tools
+--------------------
+
+Use the Microsoft compiler, cl and Make, nmake. Say nmake -f
+makefile.msc in gdk and gtk. Be prepared to manually edit various
+makefile.msc files, and the makefile snippets in build/win32.
+
+There are also VS 2008/2010 solution and project files to build GTK+, which
+are maintained by Chun-wei Fan.  They should build GTK+ out of the box,
+provided that the afore-mentioned dependencies are installed.  They will
+build GDK with the Win32 backend, GTK+ itself (with GAIL/a11y built in),
+the GAIL-Util library and the gtk-demo program.
+
+Please refer to the following GNOME Live! page for a more detailed ouline
+on the process of building the GTK+ stack and its dependencies with Visual
+C++:
+
+https://wiki.gnome.org/Projects/GTK+/Win32/MSVCCompilationOfGTKStack
+
+Alternative 1 also generates Microsoft import libraries (.lib), if you
+have lib.exe available. It might also work for cross-compilation from
+Unix.
+
+I (Tor) use method 1 myself. Hans Breuer has been taking care of the MSVC
+makefiles. At times, we disagree a bit about various issues, and for
+instance the makefile.msc files might not produce identically named
+DLLs and import libraries as the "autoconfiscated" makefiles and
+libtool do. If this bothers you, you will have to fix the makefiles.
+
+Using GTK+ on Win32
+===================
+
+To use GTK+ on Win32, you also need either one of the above mentioned
+compilers. Other compilers might work, but don't count on it. Look for
+prebuilt developer packages (DLLs, import libraries, headers) on the
+above website.
+
+Multi-threaded use of GTK+ on Win32
+===================================
+
+Multi-threaded GTK+ programs might work on Windows in special simple
+cases, but not in general. Sorry. If you have all GTK+ and GDK calls
+in the same thread, it might work. Otherwise, probably not at
+all. Possible ways to fix this are being investigated.
+
+Wintab
+======
+
+The tablet support uses the Wintab API. The Wintab development kit is
+no longer required. The wintab.h header file is bundled with GTK+
+sources. Unfortunately it seems that only Wacom tablets come with
+support for the Wintab API nowadays.
