85a96d1e06 [client] all: use DEBUG_UNREACHABLE instead of assert 
Due to the way assert is defined in standard C, compilers in release mode
will not treat it as unreachable. This explains a lot about those pesky
uninitialized variable bugs, actually.

for depth to be well-defined. Therefore, we should set gl_Position.zw to
vec2(0.0, 1.0).

b3db1ba10b [client] egl: eliminate GLsync object leaks 
It used to be the case that we overwrite this->sync even if it was non-zero

This commit ensures that sync objects are deleted when they are replaced.

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.

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.
