87aac8cf03 [client] egl: use buffer age extension to render only damaged parts
We avoid rendering any area that has not changed since the buffer was used
and also not covered by an overlay.

2dca056526 [client] egl: refactor damage mesh generation into desktop_rects
This mesh will later be used to render only damaged portions of the desktop.
We also moved the coordinate transformation for damage overlay into a matrix
and computed by the shader.

5d5e4ede1a [client] egl: use new EGL damage count semantics
After the damage queue PR, EGL damage count 0 means no change, and -1 means
invalidate the entire window. However, several other places have different
semantics, and we are not handling them correctly:

1. KVMFR uses 0 to signal invalidating the entire frame, so if we receive 0
   rectangles in egl_on_frame, we should set damage count to -1.
2. The damage overlay treated 0 as full damage, which is now incorrect. This
   is fixed, and now it treats 0 as no update, and -1 as full damage.

13d9c84dc9 [client] egl: replace monolithic EGLTexture with modular version
The way things were handled in EGLTexture is not only very hard to
follow, but broken. This change set breaks up EGLTexture into a modular
design making it easier to implement the various versions.

Note that DMABUF is currently broken and needs to be re-implemented.

23c77e8508 [client] egl: use a lock for desktop damage to eliminate all races
There used to be a possible race when a bunch of rectangle is appended, but
the total count is not updated before it's read. Using a lock eliminates
all such races.

b3b71d6f02 [client] egl: fix cursor handling when invalidating
If we invalidate the window, we used to not update this->cursorLast, and
this causes us to lose track of the cursor. Now we update this->cursorLast
unconditionally, and this fixes the issue.

134829cbf2 [client] imgui: make graph y-axis configurable
The default of [0, 50] makes sense for FPS/UPS graphs, but does not for
things like the import graph. The latter should not take more than 5 ms
for sure.

This commit allows the min/max y-axis value to be specified when registering

60a58d4d8d [client] all: make it possible to signal full window invalidation
Now that we are drawing with damage rects, when the window is hidden and
then exposed the window may not get fully redrawn. This provides
`app_invalidateWindow` for the display server backend to call when the
screen needs a full redraw.

df0397b10b [client] imgui: track last rectangles for overlays
This is necessary in case overlays change size. When this happens, we must
damage the larger of the overlays' rectangles this frame and last frame.
This erases the overlay from where it is no longer appears.

In order to do this, we must keep track of the rectangles for every overlay
with no exception. We cannot short-circuit the generation of rectangles if
we run out of buffer space, and we must allocate space for MAX_OVERLAY_RECTS
rectangles for every frame. Otherwise, we will not know where to erase the
overlay if it disappears.

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.

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.
