504bf02855 [client] x11: provide an empty rect region to XPresentPixmap
Providing None informs the comppositor that there is full screen damage,
instead we provide an empty rectangle to prevent this behaviour.

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.

0cbc529640 [client] ds: refactor common EGL swap with damage logic
This commit creates a new utility library, eglutil.h, which contains code
to detect and use EGL_KHR_swap_buffers_with_damage or its EXT equivalent.

This logic used to be duplicated between the X11 and Wayland display servers,
which is not ideal.

203ebc73eb [client] x11/opengl: enable double buffering for OpenGL
Drawing to the front buffer directly requires special handling to
prevent seeing the draw progress (avoiding glClear, etc) and as a result
the output is quite bad unless a compositor is running. Also vsync if
enabled will not function without double buffering enabled.

As OpenGL is the legacy fallback, there are no plans to implement clean
front buffer draw support, so just enable double buffering.

If a compositor has not yet started or is not running the atom
`_NET_WM_BYPASS_COMPOSITOR` may not have yet been created. As such we

5c00f73d23 [client] x11: use correct spelling of _NET_WM_BYPASS_COMPOSITOR
The incorrect spelling, NETWM_BYPASS_COMPOSITOR, somehow worked in the
past, but it appears to not work right now. Corrgan on Discord reported
the issue and confirmed that changing the spelling allowed the compositor
to be bypassed and the client to update faster than 60 Hz on his mixed
refresh rate setup.

3be645a357 [client] x11: fix BadAtom when pasting large buffers
To start a clipboard incr transfer the client has to delete the INCR
window property as the reply to the selection. This deletion generates a
property change event with the type delete, errornously triggering the
incr processing of the data. This patch corrects this by ignoring
property deletions.

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.

f9a9953071 [client] egl: use new util_hasGLExt helper to check extensions
We previously used strstr, which can be prone to false positives when
the name of one extension is a substring of another extension.

This commit creates the helper function util_hasGLExt, which asserts
that the substring found in extension list is bounded by either spaces
or the beginning/end of the string.

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.

the taskbar or as a running application as has been reported on KDE.

358515f4a8 [client] x11: Find and use the correct valuators for mouse axes
Using the first two valuators present in the event is incorrect.  Events
with only one valuator set, such as those sent by the Xorg evdev driver
when the mouse moved along one axis only, were being discarded.  On the
other hand, mice with multiple scroll wheels may be able to emit events
with two scroll wheel valuators set.

The XInput2 specification is light on details, but "Rel X" and "Rel Y"
appear to be the de facto standard names for the motion valuators.  If
valuators with those labels are not found, fall back to using valuators
with numbers 0 and 1.

d74307223f [client] x11: set the window center via WM_SIZE_HINTS
Due to the confusing nature of the x11 protocol, bit_gravity and
win_gravity are not what they appear to be. These do not describe the
window position but rather the pixels/subwindows when the window is
resized. Instead set the gravity via the WM_SIZE_HINTS property which
all modern window managers should respect.

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.

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.
