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.

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.

ba6f26393f [client] egl: add framework for multiple scaling algorithms
This commit fixes the issues with the meaning of useNearest being flipped

We define an enumeration EGL_DesktopScaleType to express the type of scaling
needed to be performed: no scaling, upscaling, or downscaling. This is
updated when either the frame size or the viewport size changes.
Previously, we only updated the useNearest when the frame size changes.

The desktop shader can now support an enumeration of scaling algorithms,
although only nearest and linear are currently implemented.

Like before, nearest is used when not scaling or upscaling, and linear is
used when downscaling.

30a888711b [client] egl: force DMA copy into texture in on_frame
This commit forces the DMA'd memory to be copied into the texture in
the EGL on_frame handler. This avoids tearing when the LG host inevitably
updates the underlying memory. We need an additional copy inside the GPU,
but this is cheap compared to copying from system memory.

We could have used logic to lock the memory buffer, but that would require
performing DMA on every frame, which wastes memory bandwidth. This
manifests as reduced frame rate when moving the mouse compared to the
non-DMA implementation.

We also keep multiple EGLImages, one for each DMA fd, to avoid issues
with the OpenGL driver.

4bceaf5505 [client] fix hang in eglSwapBuffers when exiting while not visible
eglSwapBuffers is allowed to block when called with a nonzero interval
parameter. On Wayland, Mesa will block until a frame callback arrives.
If an application is not visible, a compositor is free to not schedule
frame callbacks (in order to save CPU time rendering something that is
entirely invisible).

Currently, starting Looking Glass from a terminal, hiding it
entirely, and sending ^C will cause Looking Glass to hang joining the
render thread until the window is made visible again.

Calling eglDestroySurface is insufficient to unblock eglSwapBuffers, as
it attempts to grab the same underlying mutex.

Instead, this commit makes it so that we pass a 0 interval to
eglSwapBuffers when running on Wayland, such that we don't block waiting
for a frame callback. This is not entirely ideal as it *does* mean
Looking Glass submits buffers while hidden, but it seems better than
hanging on exit.

It also forces opengl:vsync and egl:vsync flags to off when running on
Wayland, as they are meaningless there.
