162b1b93db [client] main: don't include the swap into the render timings
If vsync is enabled the swap will block until vblank skewing the timing
metrics.

0ec66ba210 [client] main: increase render graph max scale to 10ms
Some GPUs (like my K1200) easly exceed 2ms on the render time making
this graph useless.

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
initialized to allow for this.

6c84c0eca6 [client] overlay: move keybinds and config into the overlays
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.

This is the time spent in the on_render function, not the time between
frames. Having this information helps diagnose slowdowns in renderers.

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.

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.

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.

134829cbf2 [client] imgui: make graph y-axis configurable
The default of [0, 50] makes sense for FPS/UPS graphs, but does not for
things like the import graph. The latter should not take more than 5 ms
for sure.

This commit allows the min/max y-axis value to be specified when registering
the graph.

60a58d4d8d [client] all: make it possible to signal full window invalidation
Now that we are drawing with damage rects, when the window is hidden and
then exposed the window may not get fully redrawn. This provides
`app_invalidateWindow` for the display server backend to call when the
screen needs a full redraw.

6389a06903 [client] main: let the renderer know if it's rendering a whole new frame
While the renderer can internally track this it would be better to
