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.

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.

68d8d95266 [client] config: do not attempt to load non-files as config
Currently, we load /etc/looking-glass-client.ini and/or
~/.config/looking-glass-client.ini as long as they exist, even if they are
not files. We should only load them if they are files.

a2d5c08460 [client] ui: add input:helpMenuDelay option
This option controls the time period (in ms) after which the help menu

capture mode is no longer toggled.

This fixes #527.

1a407a67b1 [client] input: add releaseKeysOnFocusLoss option
This makes dealing with window manager shortcuts that overlap with guest
keys more pleasant, while retaining the previous functionality for users
who prefer it.

For instance, previously, using Alt+Tab (or $mod as Alt in i3/sway
movement commands) would result in the guest retaining Alt as pressed.

When the guest regained focus, it would continue thinking Alt is
pressed, leading to accidentally triggering obscure shortcuts. One had
to remember to press Alt again to "unstick" things, which was
suboptimal.

0c9ecdfcb5 [client] wm: optionally disable screensaver when requested in guest
This commit adds a new option, win:autoScreensaver, which when set to yes,
automatically disables the screensaver when requested by an application
running in the guest, and enables it when the application no longer wants
it disabled.

This is useful when doing media playback in the guest.

a46a3a2668 [all] use explicit void parameter lists
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.
