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

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).

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.

f86800cc3a [client] mouse: process mouse up event even if not in view
Unless the corresponding mouse down event was on our surface, we should
not be receiving the mouse up.

This is always the case on Wayland. On some other platforms,
SDL_CaptureMouse can be used to obtain input that happens outside the
Looking Glass surface, but Looking Glass does not make use of that
function.

We may want to process a mouse up if the corresponding mouse down
initiated a drag (e.g., of a window) that was released slightly outside
of the Looking Glass surface. Previously, Looking Glass would ignore the
mouse up, and the guest would be confused into thinking the button had
never been released, not ending the drag.

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.

078a151e4f [client] wayland: update absolute mouse position
We are actually getting mouse events directly from Wayland instead of going
through SDL, so we call app_updateCursorPos in pointer motion handlers and
swallow the SDL event.

Also removed parameters for app_handleMouseBasic as it relies exclusively on
absolute positions provided by app_updateCursorPos. Wayland does not give
you relative movements at all unless grabbed and passing absolute movements
is semantically incorrect.

Note that when the cursor is grabbed, movements are handled entirely through
relativePointerMotionHandler in wayland.c and does not go through
app_handleMouseBasic at all.

0690eacc9b [client] mouse: prevent processing out of capture mode with invalid data

165c2c3566 [client] mouse: grab the pointer when entering capture mode if needed

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.

bad25c409c [client] displayserver: add new earlyInit to the interface
Some platforms such as Wayland need to set environment vairables before

the implementation an opportunity to set things up.

dc3d07302f [client] mouse: stop setGrabQuiet from grabbing/ungrabbing the pointer
As LG always operates in relitive mode, the actual pointer grab/ungrab
