5b26017a8a [client] overlay: move separator above donation prompt
It looks really weird having a separator right after a sentence ending in :.
A separator makes the list look detached from the paragraph that introduces
it, which looks awkward. Instead, this commit moves the separator before the
introducing paragraph.

Also added logic to properly pluralize the sentence.

a37b527bbd [client] main: make core overlays register before everything else
The display servers and renderers may want to register their own
overlays in the future, as such we need g_state.overlays to be

44f815409d [client] imgui: ensure the pointer shape is correct
Since we only update imgui's cursor location when the overlay is
enabled, if the last cursor position was showing a shape that is
incorrect when we re-enter the overlay the cursor will be wrong. This
corrects this by updating the location as we enter overlay mode.

This adds a new `earlyInit` call which allows the overlay to register

85f3a71dd5 [client] overlay: remember and restore the grab and pointer state
When entering overlay mode if the cursor was previously grabbed we

correct the pointer setting it to NONE or SQUARE depending on the prior
grab state.

c15d0dc672 [client] ds: waitFrame now returns a bool to force rendering if needed
X11 needs to calibrate to get the best possible latency, as such it
needs the scene to render so that the render time of the scene can be
accounted for in the delay calculation.

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.

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.

aed370c7ce [client] main: implement just-in-time render mode
When requested, JIT render mode will be used if the display server supports it.
Otherwise, a warning is generated instead.

This essentially uses the signalNextFrame logic for imgui, but for everything.
We automatically enable this mode when overlay is on.

Currently, this exposes some damage tracking bugs in the EGL renderer.
