This is not strictly an API change as GdkDrawable is typedeffed to
GdkWindow, but it changes the header, so I'm marking it as such.
gdk_cairo_create() can only be used with windows these days, so it makes
sense to pass a window. With that, we can alseo remove the
set_cairo_clip() vfunc from GdkDrawable and implement it inside
gdkwindow.c.
You should not ever ever ever call cairo_reset_clip(). If you do, your
code is broken and you deserve everything you get.
And we should definitely not support this insanity.
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.
gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.

The function converts the given surface into an alpha bitmap mask. This
is mostly useful for setting shape regions.
Also adds a new internal function _gdk_cairo_surface_extents() that
computes a surface's extents.
Only changes in headers: GdkRegion and GdkRectangle are typedeffed to
cairo_region_t and cairo_rectangle_int_t respectively. The region type
was opaque anyway so it doesn't matter and the rectangle types are
identical.

The history before this was kind of twisted as several different
approaches were tested, so that was all squashed into this initial
commit to hide the uninteresting changes and files that were later
removed.
* gdk/gdkcairo.c (gdk_cairo_create): Add a note that cairo
contexts cannot be cached for handling expose events.
Proposed by Behdad Esfahbod.

* Practically everything changed.
Change all references of GIMP Toolkit (and variations of it)
to GTK+ Toolkit, showing no mercy at all to our beloved
ancestry. (#540529)
