Prevents crashes on systems where DRM driver lacks syncobj timeline
support (e.g., Apple Silicon with Honeykrisp driver). Applications
like Zed and WezTerm would crash with 'Timeline failed importing'
when trying to use explicit sync.

Implements a new render scheduling method, where we triple buffer when necessary.
Enabled by default, improves FPS on underpowered devices.

* opengl: remove unnecessery glflush calls
glflushing forces the driver to break batching and issue commands
prematurely and prevents optimisations like command reordering and
merging.
many glFunctions already internally glflushes and eglsync creation still
has a glflush at end render. so lets reduce the overhead of these calls.
* opengl: reduce glUseProgram calls
apitrace shows cases where the same program gets called multiple times,
add a helper function that keeps track of current program and only call
it once on same program. reduces slight overhead.
* opengl: use more efficient vertex array object
use a more modern vertex array object approach with the shaders, makes
it a onetime setup on shader creation instead of once per drawcall, also
should make the driver not have to revalidate the vertex format on each
call.
* core: fix artifacts when fullscreening
fixes an issue where fullscreening a floating window that is between two monitors causes artifacts to appear on the monitor where it did not become fullscreened on
* e
for xdg-shell, we can ping the wm_base, and thus render an ANR dialog if an app dies
for XWayland, there probably is a similar method, but I don't know about it and don't care.
* window: fix resizes with an update callback
* window: fixup sendWindowSize
Remove the size argument from sendWindowSize, since it is now a member of the Window class
and we don't want any mismatches between m_vRealSize and what we report.
Remove sendWindowSize from mapWindow, since we shouldn't need it.
* window: sendWindowSize on animation begin
* window: move most calls to sendWindowSize to the animation begin
callback
* window: remove sendWindowSize in unmanaged if not fullscreen
