-Overview of Changes in 4.15.0, 21-04-2024
-=========================================
-
-This release changes the default GSK renderer to be Vulkan, on
-Wayland. Other platforms still use ngl.
-
-The intent of this change is to get wider testing and verify that
-Vulkan drivers are good enough for us to rely on. If significant
-problems show up, we will revert this change for 4.16.
-
-You can still override the renderer choice using the GSK_RENDERER
-environment variable.
-
----
-
-This release also changes font rendering settings by introducing
-a new high-level gtk-font-rendering settings which gives GTK more
-freedom to decide on font rendering.
-
-You can still use the low-level font-related settings by changing
-the new property to 'manual'.
-
----
-
-* GtkColumnView:
- - Fix infinite loops in dispose
- - Fix problems with weak ref cycles in GtkExpression
-
-* GtkListView:
-* GtkShortcutManager:
- - Track the propagation phase of added controllers
-
-* GtkGLArea:
- - Produce dmabuf textures, so graphics offload is possible
-
-* GtkTextView:
- - Support text shadows
-
-* GtkGraphicsOffload:
- - Add a black-background property
-
-* Settings:
- - Add a new gtk-font-rendering setting
-
-* Accessibility:
- - Add support for GetRangeExtents to GtkAccessibleText
- - Add support for GetOffsetAtPoint to GtkAccessibleText
- - Implement GtkAccessibleRange for scrollbars
-
-* GDK:
- - Add a callback-based cursor API
-
-* GSK:
--  Use the Vulkan renderer by default
- - Avoid an infinite recursion with offscreens in some cases
- - Optimize graphics offload to make it more likely that compositors
-   can use direct scanout
-
-* X11:
- - Fix some confusing debug messages
- - Drop a no-longer-relevant optimization that was interfering with
-   getting the current window manager capabilities
-
-* macOS:
- - Implement the color picker for macOS 10.15+
-
-* Debugging:

-### CSS Colors
-
-Colors can be expressed in numerous ways in CSS (see the
-[Color Module](https://www.w3.org/TR/css-color-5/). GTK supports
-many (but not all) of these.
-
-You can use rgb(), rgba(), hsl() with both the legacy or the modern CSS
-syntax, and calc() can be used as well in color expressions. hwb(), oklab(),
-oklch(), color(), color-mix() and relative colors are supported as well.

-### Non-CSS Colors
-
-GTK  extends the CSS syntax with several additional ways to specify colors.
-
-These extensions are deprecated and should be replaced by the equivalent
-standard CSS notions.
+GTK extends the CSS syntax with several additional ways to specify colors.
 
 The first is a reference to a color defined via a @define-color rule in CSS.
 The syntax for @define-color rules is as follows:
 
 ```
-@define-color name color
+@define-color Name Color
 ```
 
 To refer to the color defined by a @define-color rule, prefix the name with @.
 
-The standard CSS mechanisms that should be used instead of @define-color are
-custom properties, :root and var().
-
 GTK also supports color expressions, which allow colors to be transformed to
 new ones. Color expressions can be nested, providing a rich language to
 define colors. Color expressions resemble functions, taking 1 or more colors
 and in some cases a number as arguments.
 
-`lighter(color)`
- : produces a brighter variant of `color`.
+`lighter(Color)`
+ : produces a brighter variant of Color
 
-`darker(color)`

- : changes the lightness of `color`. The `number` ranges from 0 for black to 2 for white.
+`shade(Color, Number)`
+ : changes the lightness of Color. The number ranges from 0 for black to 2 for white.
 
-`alpha(color, number)`
- : multiplies the alpha value of `color` by `number` (between 0 and 1).
+`alpha(Color, Number)`

-DESCRIPTION
------------
-
-``gtk4-image-tool`` can perform various operations on images.
-
-COMMANDS
---------
-
-Information
-^^^^^^^^^^^
-
-The ``info`` command shows general information about the image, such
-as its format and color state.
-
-Showing
-^^^^^^^
-
-The ``show`` command displays one or more images, side-by-side.
-
-``--undecorated``
-
-Removes window decorations. This is meant for rendering of exactly the image
-without any titlebar.
-
-Compare
-^^^^^^^
-
-The ``compare`` command compares two images. If any differences are found,
-the exit code is 1. If the images are identical, it is 0.
-
-``--output=FILE``
-
-  Save the differences as a png image in ``FILE``.
-
-``--quiet``
-
-  Don't write results to stdout.
-
-Conversion
-^^^^^^^^^^
-
-The ``convert`` command converts the image to a different format or color state.
-
-``--format=FORMAT``
-
-  Convert to the given format. The supported formats can be listed
-  with ``--format=list``.
-
-``--color-state=COLORSTATE``
-
-  Convert to the given color state. The supported color states can be
-  listed with ``--format=list``.
-
-``--cicp=CICP``
-
-  Convert to a color state that is specified as a cicp tuple. The cicp tuple
-  must be specified as four numbers, separated by /, e.g. 1/13/6/0.
-
-Relabeling
-^^^^^^^^^^
-
-The ``relabel`` command changes the color state of an image without conversion.
-This can be useful to produce wrong color renderings for diagnostics.
-
-``--color-state=COLORSTATE``
-
-  Relabel to the given color state. The supported color states can be
-  listed with ``--format=list``.
-
-``--cicp=CICP``
-
-  Relabel to a color state that is specified as a cicp tuple. The cicp tuple
-  must be specified as four numbers, separated by /, e.g. 1/13/6/0.

-The color functions can all be replaced by combinations of calc() and color-mix().

-Variations of these replacements are possible.

-Note that GTK has historically computed mix() and shade() values in the SRGB and HSL

-/**
- * GdkCicpParams:
- *
- * The `GdkCicpParams` struct contains the parameters that define
- * a colorstate according to the ITU-T H.273
- * [specification](https://www.itu.int/rec/T-REC-H.273/en).
- *
- * See the documentation of individual properties for supported values.
- *
- * The 'unspecified' value (2) is not treated in any special way, and
- * must be replaced by a different value before creating a color state.
- *
- * `GdkCicpParams` can be used as a builder object to construct a color
- * state from Cicp data with [method@Gdk.CicpParams.build_color_state].
- * The function will return an error if the given parameters are not
- * supported.
- *
- * You can obtain a `GdkCicpParams` object from a color state with
- * [method@Gdk.ColorState.create_cicp_params]. This can be used to
- * create a variant of a color state, by changing just one of the cicp
- * parameters, or just to obtain information about the color state.

- * @data: User data for the callback
- *
- * The type of callback used by a dynamic `GdkCursor` to generate
- * a texture for the cursor image at the given @cursor_size
- * and @scale.
- *
- * The actual cursor size in application pixels may be different
- * from @cursor_size x @cursor_size, and will be returned in
- * @width, @height. The returned texture should have a size that
- * corresponds to the actual cursor size, in device pixels (i.e.
- * application pixels, multiplied by @scale).
- *
- * This function may fail and return `NULL`, in which case
- * the fallback cursor will be used.
- *
- * Returns: (nullable) (transfer full): the cursor image, or
- *   `NULL` if none could be produced.
