A side effect of vkQueuePresentKHR is the Vulkan implementation calling
wl_surface_commit() on the corresponding Wayland surface. Thus, before
this, we must synchronize the surface state (e.g. opaque region, window
geometry, etc) that changed since last time. Prior to this commit this
was done after calling vkQueuePresentKHR(), causing the surface state to
always correspond to the previous buffer state. As of this commit this
is now done before calling vkQueuePresentKHR(), thus before
wl_surface_commit().
A side effect of eglSwapBuffers* is the EGL implementation calling
wl_surface_commit() on the corresponding Wayland surface. Thus, before
swapping buffers, we must synchronize the surface state (e.g. opaque
region, window geometry, etc) that changed since the last buffer swap.
Prior to this commit, this was done after eglSwapBuffers*, causing the
surface state to always correspond to the previous buffer state. As of
this commit this is now done before swapping the buffers, thus before
wl_surface_commit().
If you want transparent region, you can just render them transparent.
If you want input shaping, use gdk_surface_input_shape_combine_region().
Also remove gtk_widget_shape_combine_region().
... and its implementation in the X11 backend.
GDK does lots of work trying to reduce the region in expose events
so that when the server sends multiple expose events, touching the
same area we can make sure to only redraw stuff once. However:
(1) this is only relevant of there's tons of delay and multiple
expose events get sent
(2) we coalesce multiple events into a single expose event anyway
(3) we do this on the frame clock
But most importantly:
(4) Since the invention of compositing, servers caches all contents
anyway

This renames the GdkWindow class and related classes (impl, backend
subclasses) to surface. Additionally it renames related types:
GdkWindowAttr, GdkWindowPaint, GdkWindowWindowClass, GdkWindowType,
GdkWindowTypeHint, GdkWindowHints, GdkWindowState, GdkWindowEdge
This is an automatic conversion using the below commands:

is_touchpad_device() for XI2 was hardcoded to look for libinput only.
Extend it slightly to correctly identify other Xorg touchpad drivers.

This is necessary so that bidnings work properly and don't make
gdk_gl_texture_release() a function on GdkTexture.
It also allows code to identify what type of texture they are dealing
with.
Finally, we can now decide to add getters later without screwing
anything up, if we want to allow people to access GL textures directly.
This is a constructor, and it needs a transfer annotation.
Sadly, the resulting introspection representation is going to be a less
than satisfactory `Gdk.gl_texture_new()`, because there is no such thing
as a GdkGLTexture in the public API.
A problem with textures is that they can become too big for GPU memory,
which would require tiling. But for tiling we only need to download
the pixels needed by the tile.
Similarly, there might be interest to not upload full textures if a
renderer knows it only needs a small part.
Both of these methods require the ability to specify an area of the
texture to be downloaded. So change the download vfunc to include
this parameter now before we add even more textures later.
A private gdk_texture_download_area() function has also been added, but
nobody is using it yet.
