334bfeecea [client] egl: correctly handle mixing imgui and non-imgui overlays 
This allows the full frame to be damaged when both types are visible.

947eac52f6 [client] renderers: treat -1 as full damage and 0 as no overlay

fdbdf6f167 [client] app: implement new overlay rendering framework 
This change set implements a framework for overlays to be registered
that make use of ImGui. See `overlay/fps` for a simple implementation
example.

6389a06903 [client] main: let the renderer know if it's rendering a whole new frame 
While the renderer can internally track this it would be better to
simply provide this information to the renderer directly so it can make
better decisions on how best to update the screen.

1a88996c47 [client] opengl: don't include <GL/glx.h> 
The OpenGL renderer backend should not depend on any particular
implementation of OpenGL, as it's used by both X11 and Wayland.

563ad18f4e [client] egl: improve cursor damage logic 
1. Use atomics and return exact cursor positions from egl_cursor_render
   to avoid race conditions between cursor render and update.
2. Instead of messing with lastCursorValid in various overlays, simply use
   the hasOverlay/hadOverlay logic for cursor damage. This simplifies the
   logic greatly.

As a result, I believe all cursor-related artifacts are fixed.

Note to reviewer: as atomic_init and atomic_store are implemented as macros,
it is currently not possible to pass structs as compound literals due to the
comma being interpreted as an argument separator by the preprocessor.

b8effaf42c [client] egl: use glGetError and codes for errors in gl* functions 
We used to use DEBUG_EGL_ERROR for gl* functions, which just yields
EGL_SUCCESS even when there are errors.

7c872d2d9e [client] egl: properly use OpenGL ES 
Instead of using the desktop <GL/gl.h>, we properly use the OpenGL ES 3.x
headers. Also, we now use GL_EXT_buffer_storage for MAP_PERSISTENT_BIT_EXT
and MAP_COHERENT_BIT_EXT as the core versions are only available in desktop
OpenGL 4.4. Similarly, we need GL_EXT_texture_format_BGRA8888 for GL_BGRA_EXT
as GL_BGRA is desktop-only.

42d8f31eba [client] imgui: use ES 3.0 and remove glew dependency 
If we specifically tell ImGui's OpenGL 3.x backend to target OpenGL ES 3.0,
then no extension loader is necessary.

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.
