b6fa296d5a [client] x11: work around issue with desktop switch on i3
For an unknwon reason when LG is on another desktop (hidden) and the
user switches to that desktop, the first attempt to grab the pointer
results in a GrabFrozen result. This adds some simple retry logic to
attempt again after a short (100ms) delay which seems to resolve the
issue.

12840a8324 [client] x11: load glXSwapIntervalEXT dynamically
The Linux OpenGL ABI does not guarantee that glXSwapIntervalEXT will be
exported statically from any library, and indeed on some systems this
function does not link at load time, e.g. with amdgpu-pro. All other
GLX functions that we use are from GLX 1.0, which is guaranteed to be
exported statically.

This commit solves this issue by using glXGetProcAddressARB to load the
function. Note that only the ARB version of glXGetProcAddress is
guaranteed to exist by the Linux OpenGL ABI, which is why we must use
it.

1fd726eed7 [client] x11: be less sensitive to frame skips
External events like launching other applications can cause latency
spikes while X11 initializes the application, we should only start
adjusting our delay if we see excessive skips over a 1s period.

64da3465b8 [client] x11: invalidate the full window after timeout from expose
Invalidating the entire window on an Expose event causes poor WM
performance when dragging the window around. Instead flag to redraw and
wait for the expose events to stop for 100ms before doing it.

c15d0dc672 [client] ds: waitFrame now returns a bool to force rendering if needed
X11 needs to calibrate to get the best possible latency, as such it
needs the scene to render so that the render time of the scene can be
accounted for in the delay calculation.

0f7fa32d12 [client] x11: move sleep and calibration code outside of the event loop
Sleeping in the x11 event loop is not ideal as it will introduce latency
when processing other events, instead do this in the waitFrame handler.

7f6fd02d06 [client] x11: Add event handling for ungrabed mouse press/release
The imgui overlay requires input even if the display is not captured and
operating in raw mode. XInput2 correctly only sends
XI_Press/ReleaseButton events if the device has not been captured, as
such it's safe to handle both raw and non raw buttons events at the same
time.

0cbc529640 [client] ds: refactor common EGL swap with damage logic
This commit creates a new utility library, eglutil.h, which contains code
to detect and use EGL_KHR_swap_buffers_with_damage or its EXT equivalent.

This logic used to be duplicated between the X11 and Wayland display servers,
which is not ideal.

203ebc73eb [client] x11/opengl: enable double buffering for OpenGL
Drawing to the front buffer directly requires special handling to
prevent seeing the draw progress (avoiding glClear, etc) and as a result
the output is quite bad unless a compositor is running. Also vsync if
enabled will not function without double buffering enabled.

As OpenGL is the legacy fallback, there are no plans to implement clean
front buffer draw support, so just enable double buffering.

5c00f73d23 [client] x11: use correct spelling of _NET_WM_BYPASS_COMPOSITOR
The incorrect spelling, NETWM_BYPASS_COMPOSITOR, somehow worked in the
past, but it appears to not work right now. Corrgan on Discord reported
the issue and confirmed that changing the spelling allowed the compositor
to be bypassed and the client to update faster than 60 Hz on his mixed
refresh rate setup.

e70cfd84fb [client] egl: use eglSwapBuffersWithDamageKHR for cursor-only updates
Instead of damaging the entire surface when rendering a cursor move,
we can use the EGL_KHR_swap_buffers_with_damage extension to only
damage the part of the window covered by the cursor. This should
reduce the cursor movement latency on Wayland.

f9a9953071 [client] egl: use new util_hasGLExt helper to check extensions
We previously used strstr, which can be prone to false positives when
the name of one extension is a substring of another extension.

This commit creates the helper function util_hasGLExt, which asserts
that the substring found in extension list is bounded by either spaces
or the beginning/end of the string.
