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.

f4c1927f56 [client] ds: added new getFullscreen operation
As the window manager may change our mode to full screen without our

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.

ff0a859ceb [host] nvfbc: avoid recreating mouse hook and 1x1 window
The mouse hook code is very fragile, and we would like to avoid unhooking
and re-hooking as much as possible.

After this commit, this is done only once, and the hook and 1x1 window is
only destroyed upon exit. This, of course, comes with the downside of
the slight performance penalty if the guest machine is used directly while
the host is running and the client is not running.

1b48ac842a [host] nvfbc: fix resource leak when pointer thread creation fails
Moving NvFBCToSysSetup to nvfbc_init means that when the pointer thread
fails to be created, NvFBCToSysRelease needs to be called.

To resolve such cleanup issues in the future, we instead call nvfbc_deinit,
which should cleanup everything that needs to be cleaned up. fails.

a702c912ae [host] nvfbc: move NvFBCToSysCreate into nvfbc_init
When NvFBCToSysCapture reports recreation is required, we return
CAPTURE_RESULT_REINIT, which eventually calls nvfbc_deinit and then
nvfbc_init.

However, the NvFBC object is actually created in nvfbc_create, which
means the NvFBC object is never actually recreated. The result is an
endless cycle of NvFBC asking for recreation. This commonly manifests
as the client waiting endlessly for the host when the guest machine
reboots.

In this commit, the NvFBC object creation is moved into nvfbc_init,
and when recreation is required, it will actually be recreated.

acc3298344 [host] nvfbc: cleanup threads created by nvfbc_init on failure
mouseHook_install and dwmForceComposition both create threads, but these
are only freed in nvfbc_deinit which is not called if nvfbc_init fails.
These should be freed if the pointer thread fails to be created, as
nothing else could be cleaning it up.

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).

1761ea2b9b [host] windows: move log path to %ProgramData%\Looking Glass (host)
Instead of using %windir%\Temp, which is not accessible by default and
contains a lot of unrelated files, as the location for our log files,
this commit moves it to %ProgramData%\Looking Glass (host), which will
be a dedicated directory just for the LG host log files. This applies
to both the host application logs and the service logs.

Also, we now switched to using PathCombineA from shlwapi.dll instead
of using snprintf, which greatly simplifies the code. PathCombineA
guarantees that the path would not overflow a buffer of MAX_PATH.

b97130cf20 [host] nvfbc: generate cursor position update on startup
Before this commit, the NvFBC backend only generated the first cursor
position update when the mouse moves. Therefore, if the user does
not move the mouse, the cursor will be shown at (0, 0), which is not
ideal.

This commit changes this behaviour to unconditionally generate a
cursor update when the mouse hook initializes.

6b5842d2ff [host] cmake: use -march=nehalem by default
Nehalem is the minimum requirement for the host application as it makes
use of SSE4.1 instructions, as such we should default to compling with
it instead of `-march=native` so that when the binary is distributed it
will operate on foreign systems.
