f8e1ab8f31 [client] renderers: add new needs_render method to the interface
With jitRender the renderer needs to tell the main application if it
needs to be rendererd, such as during the initial splash screen fade
out.

41c5688fca [client] overlay: let the overlay know if it's in interactive mode
This also removes the need for the flags member as the overlay can just

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.

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
simply provide this information to the renderer directly so it can make
better decisions on how best to update the screen.

e70cfd84fb [client] egl: use eglSwapBuffersWithDamageKHR for cursor-only updates
Instead of damaging the entire surface when rendering a cursor move,
we can use the EGL_KHR_swap_buffers_with_damage extension to only
damage the part of the window covered by the cursor. This should
reduce the cursor movement latency on Wayland.

0f2fd84724 [client] ds: avoid util_cursorToInt when warping pointer
Using util_cursorToInt messes with the error tracking for normal movements,
and is not necessary since we are computing an absolute position on the
client window.

Instead, we should pass doubles directly to display servers and let them
decide how to best handle them. For example, XIWarpPointer accepts doubles
directly.

00c2773e6b [client] ds: separate grab and capture logic
Currently, (un)grabPointer is used both for tracking/confining the mouse
in normal mode, as well as entering/exiting capture mode. This makes it
impossible to use separate cursor logic for capture mode, which is needed
to deal with overlapping windows for the Wayland backend.

This commit creates separate (un)capturePointer for entering/exiting
capture mode. There should be no behaviour changes.

d0a12f6097 [client] ds: detect when the cursor exits into an overlapping window
This adds a new method to the display server interface to allow the
application to notify the ds when there is a guest cursor position
update along with the translated local guest cursor position. This makes
it possible for the display server to keep the local cursor position in
sync with the guest cursor so that window leave events can be detected
when the cursor would move into an overlapping window.

Wayland currently just has a stub for this, and the X11 implementation
still needs some minor tweaking.

270631f1b9 [client] ds: add surface-only warp variant
This commit converts the output of ds->getProp(LG_DS_WARP_SUPPORT) to
an enum containing three items:

* LG_DS_WARP_NONE: warp is not supported at all
* LG_DS_WARP_SURFACE: warp is possible, but only inside the window
* LG_DS_WARP_SCREEN: warp is possible anywhere on the screen

LG_DS_WARP_NONE corresponds to the old false return value, and
LG_DS_WARP_SCREEN corresponds to the old true return value.

LG_DS_WARP_SURFACE is designed for Wayland, where warping is possible,
but only in our window. In this case, since we cannot warp outside
the window, we can warp the cursor to the edge when we attempt to exit.
If the cursor leaves, the normal leave routine gets called, and the
cursor disappears. If the cursor does not end up leaving, we grab it
again.

89b73512ad [client] renderer: add ability to toggle the FPS display
Before, if you want to see the FPS, you need to close the client and
restart it with the -k switch to see the FPS. This is annoying.

This PR introduces a new keybind, ScrollLock+D, which, when pressed,
toggles the display of the FPS.

This is implemented for both EGL and OpenGL backends.

ecebcc4c35 [client] opengl: make ds functions optional
Using a macro ENABLE_OPENGL just like ENABLE_EGL to optionally remove
OpenGL implementation code. This is mostly because on Wayland it's just

56c80a15e6 [client] wayland: gracefully degrade when protocols are unsupported
zwp_relative_pointer_manager_v1 and zwp_pointer_constraints_v1 are
supported by GNOME/KDE/sway (and most other compositors), but they are
not a required part of the protocol.

Some users also run software in one-off nested compositors like cage[0]
for an extra layer of isolation; cage, at least, does not support
pointer captures.

This commit makes Looking Glass warn when an optional protocol is
unsupported, and fail if a required one is missing. Pointer grab paths
have a new guard against the aforementioned protocols being missing.

701dfd5694 [client] mouse: do not grab the pointer if the platform has no warp
Platforms such as Wayland have no abillity to warp the cursor, as such
can not operate in an always relative mode. This property allows
platforms to report the lack of warp support and prevent LG from
grabbing the pointer.
