Copying to the clipboard is not a buffer mutation, so calling
gtk_text_buffer_begin_user_action() and _end_user_action() is only
confusing apps which connect to these signals in order to build undo
stacks or otherwise track buffer changes. Most likely, these apps
either didn't notice the bugus undo step or simply work around it.

The default value of the icon-spacing style property was 0, which
is just not good. Themes are of course free to change this anyway.

When the foreign window already has a GdkWindow, we forget to take
an extra references, leading to crashes later on. Patch by
Karl Tomlinson, bug 607061.
(cherry picked from commit beddf67e56)
Patch from bug #591186. It won't have any effect in this branch as the
whole XP-and-later theming code is broken and disabled, but when/if
that is fixed, then this patch should help.
This is exposed by overshooting in a HildonPannableArea. Leaking
a GtkTreeRowReference also means leaking the whole model, since
the GtkTreeModel reference count is increased for each row
reference.
Fixes bug #607770 - Leak in GtkTreeView with HildonPannableArea

If e.g. the right edge of the leftmost rectangle is near MIN_INT, and
the left edge of the rightmost rectangle is large then subtracting these
can lead to an integer overflow, making the resultant "width" falsely
positive, thus returning a very wide result instead of the expected
no-intersection result.
We avoid the overflow by not doing the subtraction unless we know the
result will be positive. There are still risks for overflow if x + width
or y + width is larger than MAXINT, but we won't ever overflow for valid
rects now.

We need to do this because otherwise the implicit button grab for this
(native) window will not deliver the button events not selected for
by this window. This is a problem because non-native child windows may
select using a wider event mask, and we can't emulate these events if we
don't get the native events.
Fixes bug #607508

Any old cairo_surface referencing the old impl window will be wrong
when we make a window native, so drop it.
This fixes bug #599511
(cherry picked from commit e31a6d1fea)
When a cairo surface is requested for direct window access (i.e. not
when double-buffering) we can't really track when the actual drawing happens
as cairo drawing is not virtualized. This means we can't properly flush
any outstanding window moves or implicit paints.
This actually causes problems with e.g. abiword (bug #606009) where they
draw without double-buffering. If you press down it scrolls the window
and then draws the caret, but the caret drawing does not flush the
outstanding move from the scroll, so the caret gets drawn on the wrong
screen.
We fix this by never allowing either implicit paints or outstanding window
moves on impl-windows where any windows related to it has an outstanding
direct cairo surface. Luckily this is not very common so in practice this
doesn't matter much.
(cherry picked from commit 841fa47715)
It may happen that a window gets destroyed during painting, if so
we should not draw the implicit paint double-buffered pixmap to it
as that will cause a BadDrawable X error.
