Since the display server owns a graph, it was necessary to move the overlay
graphs destruction so that it happens after display server destruction.

903cc9815f [client] x11/sdl/wayland: implement new minimize (stub for wayland)

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.

389d8824e2 [client] wayland: handle output scale changes
If the scale factor of an wl_output changes while the client is running,
the maximum scale factor is not updated. This may result in incorrect
scaling.

Therefore, when the scale factor is changed, we should generate a
resize event.

9b688909b0 [client] wayland: support LG_DS_WARP_SURFACE
This commit implements support for LG_DS_WARP_SURFACE, as well as a warp
routine based on cursor confines.

This may not necessarily work for all compositors. As such, the old cursor
routines are still kept, and used when wm.warpSupport is set to false.

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.

a450e0f8f5 [client] wayland: better self-copy detection
This new implementation uses a special mimetype to tag data copied from
the guest, instead of using flags. This should make it easier to
implement asynchronous transfers in the future. Also, it's simpler to
understand and less error-prone.

The pid is included in the mimetype in order to distinguish between
different instances of looking glass: you might want to copy between
two different VMs, for example.

b0f9d2f713 [client] spice/wayland: improve cursor tracking logic
One of the major issues with the old tracking code is a data race
between the cursor thread updating g_cursor.guest and the
app_handleMouseBasic function. Specifically, the latter may have
sent mouse input via spice that has not been processed by the guest
and updated g_cursor.guest, but the guest may overwrite g_cursor.guest
to a previous state before the input is processed. This causes some
movements to be doubled. Eventually, the cursor positions will
synchronize, but this nevertheless causes a lot of jitter.

In this commit, we introduce a new field g_cursor.projected, which
is unambiguously the position of the cursor after taking into account
all the input already sent via spice. This is synced up to the guest
cursor upon entering the window and when the host restarts. Afterwards,
all mouse movements will be based on this position. This eliminates
all cursor jitter as far as I could tell.

Also, the cursor is now synced to the host position when exiting
capture mode.

A downside of this commit is that if the 1:1 movement patch is not
correctly applied, the cursor position would be wildly off instead
of simply jittering, but that is an unsupported configuration and
should not matter.

Also unsupported is when an application in guest moves the cursor
programmatically and bypassing spice. When using those applications,
capture mode must be on. Before this commit, we try to move the guest
cursor back to where it should be, but it's inherently fragile and
may lead to scenarios such as wild movements in first-person shooters.

543d660ccc [client] wayland: check for the Wayland platform extension
We used to test for the EGL_KHR_platform_base and EGL_EXT_platform_base,
but those only really signal the availability of eglGetPlatformDisplay(EXT)
functions, not whether the constant EGL_PLATFORM_WAYLAND_KHR or
EGL_PLATFORM_WAYLAND_EXT is accepted by their respective functions.

Instead, we switch to test for the extensions that tells us whether the
Wayland platform is supported.

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).

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.
