cf3e816603 [client] probe Wayland backend first 
`$DISPLAY` will be set even in a Wayland session, which causes LG to
initialize itself under Xwayland unless it is explicitly compiled with
`-DENABLE_X11=OFF`.

We could add a Wayland check within the X11 backend, but reordering the
code-generated array seems like a better solution.

8559b354ae [client] egl: always render desktop texture as opaque 
We ask for 32-bit colour buffer when creating the EGL context. On Wayland,
this sometimes give contexts with alpha channels, resulting in unwanted
transparency. So we clear the alpha channel in the desktop shader.

We also switch to using constant alpha for blending the splash, which
avoids more alpha issues.

ec921d7f39 [client] spice: correctly ungrab keyboard when grabKeyboardOnFocus=no 
When input:grabKeyboardOnFocus=no, exiting capture mode should ungrab
the keyboard. Otherwise, focusing the window doesn't grab the keyboard,
but toggling capture mode would leave the keyboard stuck in a grabbed
state until defocused.

637a7625d2 [client] wayland: allow EGL/OpenGL vsync to be set to on 
This effectively reverts 4bceaf5.

Upstream ticket: https://gitlab.freedesktop.org/mesa/mesa/-/issues/4180

Commit 941c651 makes working around the hang in LG itself not as
annoying as before.

In the future, we can bypass this entire issue by implementing our own
swapchain and listening to frame callbacks ourselves.

e6ebcec689 [client] spice: don't send zero deltas for Wayland input 
While a compositor will never send us 0-delta motion events, they can
still end up as 0-deltas post-projection, consuming QEMU buffer space
for no reason.

This should help with mouse skipping issues.

25e74301be [client] wayland: fix copying rich text into guest 
Before this, copying rich text ends up with a lot of funky behaviour,
for example:
* copying text from Discord shows up as HTML unless pasted into a text
  editor first
* copying text from Firefox shows up as the single letter h

This commit fixes all the above issues.

Due to the change in logic, we now use the first text format offered
instead of the last, which is almost certainly the preferred form.
Doing this gets us proper Unicode support, or Unicode characters would
end up as escapes of the form \uXXXX (this is used in the fallback
forms for applications without UTF-8 support).

941c651fad [client] unconditionally quit on second SIGINT 
Under some circumstances, Looking Glass can hang when SIGINT'd, for
instance, if it's stuck waiting on spice I/O that won't complete because
the guest is misbehaving.

This commit provides an escape hatch for such cases, so one doesn't have
to reach for `kill -9 $(pidof looking-glass-client)`.

908aa84599 [client] wayland: use acceleration in capture mode unless rawMouse 
We are forced to use accelerated movement in regular mode as that is how the
host machine cursor moves and we want the cursors to line up (since Wayland
cannot do warps). To avoid a change in sensitivity when toggling capture
mode on/off, we should use accelerated deltas for capture mode as well,
unless the user explicitly asks for raw input with input:rawMouse.

6077dcc123 [client] spice/wayland: fix jitter when moving the cursor slowly 
It does not make sense to accumulate fractional error in non-capture mode
as you know exactly where the cursor is supposed to be, at least on Wayland.

On Wayland, we base movements on the current guest position and desired
target position, and the accumulated errors only skew our movements.
