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.

b9a7ce17fe [client] egl: use queue of damages
This prevents damage from being overwritten when frames are received
faster than could be rendered.

This implementation cycles between two queues, removing all need for
memory allocation.

This change allows the window position and size to be changed, and
saved/loaded by imgui. Additionally the plots will now scale to the

3043296e52 [client] ds: add optional method signalNextFrame(LGEvent)
This method takes an LGEvent and signals it when the next frame should be
rendered in time for the next vblank.

We will be using this to render imgui at screen refresh rate, but this could
potentially be used later to implement a better form of vsync for supported
display servers.

This must be invoked before swapping buffers.

7f6fd02d06 [client] x11: Add event handling for ungrabed mouse press/release
The imgui overlay requires input even if the display is not captured and
operating in raw mode. XInput2 correctly only sends
XI_Press/ReleaseButton events if the device has not been captured, as
such it's safe to handle both raw and non raw buttons events at the same
time.

75e57baf6c [client] config: optionally load config from XDG_CONFIG_HOME
We look for the client config in $XDG_CONFIG_HOME/looking-glass/client.ini.
This is done because it's more conventional, and also allows us to add
additional configuration files, e.g. for the host.

We fallback to $HOME/.config as is standard, and then as a last resort use
getpwuid(getuid())->pw_dir. This is also recommended by the getpwuid manpage:

> An application that wants to determine its user's home directory should
> inspect the value of HOME (rather than the value getpwuid(getuid())->pw_dir)
> since this allows the user to modify their notion of "the home directory"
> during a login session.

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.
