This allows the client to work when the OpenGL implementation fails if
EGL_RENDER_BUFFER is passed, printing a warning. This should fix issues
with Nvidia proprietary drivers on Wayland.

NVIDIA still do not implement a complete/working DMABUF implementation

70a751b58d [client] egl/filters: bypass setup/prepare logic if disabled/inactive 
filters are now not run if `egl_filterSetup` returns false, as such we
do not need additional `enable` checks in `prepare` or `run` and we can
bypass the filters even earlier if they are not enabled reducing load.

74418106de [client] egl: skip downscale filter setup when not enabled 
Since this->prepared will never be set to true unless the filter is
enabled, this results in the framebuffer setup being done every frame
for no reason, causing a lot of texture reallocations.

6370350006 [client] opengl: indirectly access non-OpenGL 1.3 functions 
This commit adds check for the extensions that we need and then calls
the functions indirectly through gl_dynprocs.

This should improve compatibility with older versions of OpenGL, as we
now fallback to the ARB extensions if possible, and in the case of
glGenerateMipmap, we can handle the function not existing at all.

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.

df4a964496 [client] spice: stop if pointer left during guest warp

The translucent white modal background sort of cancels out the dark

instead further darken the background.

For consistency, we now use igGetColorU32Col(ImGuiCol_ModalWindowDimBg)

multiple places.

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.

37196f1f0e [client] config: disable JIT rendering by default 
Without configuring Wayland compositors to send frame callbacks as late as
possible, JIT rendering can increase latency by more than one frame.

For example, by default, sway asks applications to render right after a
vblank, and does its own composition right after a vblank, resulting in
~2 frame's worth of latency. If max_render_time is set on the output,
it composes that many milliseconds before the vblank, losing ~1 frame's
worth of latency. If max_render_time is set on the window also, the frame
callback is sent that many milliseconds before composition, and we achieve
perfectly low latency.

Therefore, out of the box, JIT rendering should not be enabled, as manual
compositor configuration is required for optimal results.

For reference, the following sway settings results in the best latency:

    output <insert output name> max_render_time 1
    for_window [app_id="looking-glass-client"] max_render_time 1

This reverts commit 3baed05728.

Currently, we scale the desktop up to the next largest integer, and rely on

This is obviously undesirable.

In this commit, we attempt to detect the actual fractional scaling by finding
the current active mode in wl_output, and dividing it by the logical screen
size reported by xdg_output, taking into consideration screen rotation.

We then use wp_viewporter to set the exact buffer and viewport sizes if
fractional scaling is needed.

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.

bb60107a3b [client] wayland: dispatch events through libdecor when using it 
Currently, we dispatch the events on the wayland display server ourselves.
This is fine when using the cairo backend of libdecor, as it does the same
thign we do, but other backends may require other things to be dispatched.

This commit lets libdecor dispatch events instead through libdecor_get_fd
and libdecor_dispatch, which should hopefully makes things less sketchy.

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.
