This was only promoted to core in 3.0, but Mesa's supported it
unconditionally since around 7.0 even in 2.1 contexts, so this is not a
particularly onerous requirement.

Syncronized subsurfaces that call into `merge_pending_state` might
otherwise not create new destroy handlers, ending up with a invalid
handler ids, throwing errors and leaking.

It might be the case that handling an event induces the stream to
trigger completion, hence removing itself from the list. In that
case we would operate on the no longer valid list element to fetch
the next one.
Keep a pointer to the next element beforehand, so we can tiptoe
over streams that did remove themselves.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/869
The streams were only detached from MetaX11Display (and its event handling)
on completion. This is too much to expect, and those might be in some
circumstances replaced while operating.
Make those streams detach themselves on dispose(), so we don't trip into
freed memory later on when trying to dispatch unrelated X11 selection events.

Instead of doing a roundtrip to the X server before setting it, rely on
the previous value fetched before the configuration was sent over DBus.
This matches the argument check we already do elsewhere, and will allow
us to more easily add an additional condition to determine if underscan
is supported.

Midscene tracking was used at a time that some Cogl users
could call random OpenGL API without going through Cogl.
That is not allowed anymore, and certainly not done by
Mutter and GNOME Shell.
Remove midscene tracking from CoglFramebuffer.

CoglJournal tracks a few OpenGL states so that they can
be batch-applied if necessary. It also has a nice property
of allowing purely CPU-based glReadPixels() when the scene
is composed of simple rectangles.
However, the current journal implementation leaves various
other GL states out, such as dithering and the viewport.
In Clutter, that causes the journal to be flushed when
picking, touching the GPU when we didn't really need to.
Track the viewport of the framebuffer in the journal so that
we can avoid flushing the journal so often.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/402
CoglFramebuffer checks the passed buffer bits in order to
detect when the fast path (that uses the journal) should
be used.
However, it also modifies one of the buffer bits that is
checked for the fast path, meaning we never actually hit
the fast path on cogl_framebuffer_cleaf4f().
Check the depth and color buffer bits before modifying them.

Previously picking was done on an int (x,y) to address a particular pixel.
While `int` was the minimum precision required, it was also an unnecessary
type conversion.
The callers (input events mainly) all provide float coordinates and the
internal picking calculations also have always used floats. So it was
inconsistent and unnecessary to drop to integer precision in between those.
ABI break: This changes the parameter types for public function
`clutter_stage_get_actor_at_pos`, but its documentation is already
sufficiently vague to not need changing.
