As the window manager may change our mode to full screen without our
request we must ask the ds backend for the current state when we want to
toggle the mode.
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.
This effectively reverts 4bceaf5.

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.
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.
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).
If the renderer fails to start it sets the run state to stopped, having
lgInit where it was causes this to be reset to running triggering
invalid usage of g_state.lgmp.
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)`.
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.
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.
Build failed with _FORTIFY_SOURCE enabled because the compiler couldn't
ensure the switch statements didn't hit the default arm and thus wouldn't
define the variables. Adding a statically failing assert makes sure that
all code paths either define the variables or fail early.

When using the meta resize feautre the cursor is over the client window,
and as such the application continues to receive motion events. This
causes the window size to spaz out.
As the screen output rotation can be changed on the fly, if it has been
rotated to 90 or 270 the nearest flag will be incorrect, so we perform
this check here and override the provided value.
This is an ugly hack for now that will get us over the line for Beta 3,
after which will need to be addressed and people will need to be
informed that their configured escape key will have changed.
If the guest has it's output rotated (ie, landscape) we must rotate and
translate the pointer draw location, as well as all the translations of
cursor coordinate spaces based on the rotation, along with any local
rotations that may also be applied.
It appears that Wayland pointer motion handlers are called even when relative
mouse mode is enabled. The events they generate break first-person games.
This commit disables those handlers when relative mouse is enabled.
