That way we don't need to move the clip rounded rect manually through
the vertex shader into the fragment shader but can just look at the push
constants.
Simplifies shaders a lot.
Passing a rectangle with zero width or height to xdg_shell-v6
set_anchor_rect() will cause a protocol error and terminate the client,
as with gedit when pressing the Win key.
Reason for this is because the rectangle used to set the anchor comes
from gtk_text_layout_get_iter_location() which uses the pango layout
width/height, which can be empty if there is not character at the given
location.
Make sure we don't use 0 as width or height as an anchor rectangle to
avoid the protocol error, and compensate the logical position of the
given rectangle if the size is changed, so that the actual position
remains as expected by the client.

Images with just an aspect ratio, but without a size, should be scaled
to be fully visible in the given area.
But we scaled them to completely cover the given area, which made them
partially invisible.
Reftest included.
gtk_snapshot_pop() => removed
gtk_snapshot_pop_and_append() => gtk_snapshot_pop()
So now there is no way to get a rendernode out of the snapshotting API
until you gtk_snapshot_finish().
... and use it.
The function is a bit awkward because it requires 2 calls to
gtk_snapshot_pop(), but once you accept that, it's very convenient to
use, as can be seen by the 2 implementations.
This is a free-form tab that can contain information about the
system environment. To see it, set GtkAboutDialog::system-information
to a non-NULL value.

The Mesa Vulkan drivers need XInitThreads() being called, because their
implementation has to use threads.
And I don't want to make the call depend on if Vulkan is compiled in
because that makes GTK's X11 behavior depend on compile-time flags, so
it's always called.
This way, we ensure that files that are built during make always get
properly listed. And we ensure that creating the resources actually
depends on them.
We already take ints when setting the translation, so it can't
currently take any other values. Additionally, I was seeing large
costs in int -> double -> int for the rects in
gtk_snapshot_clips_rect(), as all callers really are ints (widget
allocations) and the clip region is int-based.
This change completely cleared a 2% rectangle_init_from_graphene from
the profile and is likely to have nice performance effects elsewhere
too.
The width/height/aspect getters are called a lot, and almost all
callers already verify it from _gtk_css_image_get_concrete_size (),
so just skip these checks.
