e914e56c48 [client] stop the cursorThread if video feed is disabled
The cursorThread prevents the host from going to sleep when the
video feed is disabled as it's subscribed to the cursor queue. Stopping
the cursorThread will unsubscribe from the queue and allow the host
application to disable capture.

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
This prevents attempts to grab the pointer after the guest side warp
finishes if the pointer has left the window in the meantime. On Wayland,
this would result in the pointer moving to the middle of the window when
the confine is created.

79a9127c04 [client] imgui: use consistent modal background colours
The translucent white modal background sort of cancels out the dark

instead further darken the background.

For consistency, we now use igGetColorU32Col(ImGuiCol_ModalWindowDimBg)
to draw the overlay background, to avoid hardcoding the same colour in
multiple places.

9bd205a527 [client] imgui: fix modifier key modification race
imgui really hates it when we update the modifier key state after igNewFrame.

According to the documentation for eglQueryString:

Therefore, we should check EGL by doing:

Indeed, the old way of eglQueryString(EGL_NO_DISPLAY, EGL_VERSION) works on
libglvnd but not using mesa's libEGL.so directly.

Also added a warning to make it more obvious that EGL is not available.

After the damage queue PR, EGL damage count 0 means no change, and -1 means

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.

b3ca872cef [client] wayland: improve fractional scale handling
Currently, we scale the desktop up to the next largest integer, and rely on
the wayland compositor to scale it back down to the correct size.
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.

f1b1da60ea [client] imgui: improve method for high DPI
We now give ImGui the true logical size of the window and tell it to scale
the framebuffer. To fix the blurry fonts, we continue to load fonts at the
scale necessary for the DPI and use FontGlobalScale to shrink the fonts back
to the logical size. The font rectangle is then expanded by the framebuffer
scaling, resulting in good text rendering.

This method has the advantage of not messing up the sizes of resizable
overlays when moving across monitors.

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.

3c0ebd54ec [client] main: improve frame rate sync lock with the guest
If the guest is not sending frames at a constant rate, the minimum FPS

timeout value allowing this value to be dynamic.

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.
