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.
The display servers and renderers may want to register their own
overlays in the future, as such we need g_state.overlays to be
initialized to allow for this.
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
options before actually being intialized. Also the keybind handling and
state tracking for each overlay has been moved internal to the overlay
itself.
When entering overlay mode if the cursor was previously grabbed we
should restore the state when exiting overlay mode. This will also
correct the pointer setting it to NONE or SQUARE depending on the prior
grab state.
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.
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.
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.
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.
