3134ec84de [host] dxgi: add support for downsampling the capture before sending
This is an experimental & incomplete feature for those using
supersampling. Anything > 1200p will be downsampled by 50% before
copying out of the GPU to save on memory bandwidth.

Unfinished! Has issues with damage tracking and currently can not
be configured. Only dx11 has been tested at this point, everything
else will likely have problems/crash.

132d0e3c42 [client] audio/pw: pw_stream_get_time() deprecated
pw_stream_get_time() is deprecated in PipeWire 0.3.50.
Use pw_stream_get_time_n() instead based on PipeWire
library version.

6d06320fb2 [client] audio/pw: fix muting
Pipewire documents the mute parameter as a bool, however `pw_stream_set_control` expects a float value and converts it to a bool.

48cf099638 [client] input: fix confine_pointer argument marshalling
Under Wayland, if the mouse pointer is disconnected whilst captured
(like say via KVM switch), the waylandWarpPointer code will be called
but the pointer will be NULL. This results in the cryptic message:

error marshalling arguments for confine_pointer (signature noo?ou): null value passed for arg 2
Error marshalling request: Invalid argument

This patch adds a check on the wlWm.pointer pointer before attempting
to warp the pointer, and avoids the crash.

72033f3822 [client] audio: reduce hardcoded minimum latency
The current minimum target latency is partially based upon the default qemu
behaviour whereby audio packets are delivered in a sawtooth pattern, with
packet timestamps drifting between 5ms above and below the measured clock.
This 5ms error is baked into the minimum target latency to avoid
underrunning.

This sawtooth pattern can be reduced by specifying a lower timer period in
the qemu configuration, so remove it from the hardcoded minimum latency and
add it to the default configurable buffer latency instead. This allows
users that have configured their VM appropriately to reduce the overall
latency.

c2523be4b4 [client] audio: reduce resampler latency
The best quality resampler has an intrinsic latency of about 3ms, and the
processing itself takes another 1-2ms per 10ms block. The faster setting
has an intrinsic latency of about 0.4ms, with about 0.04ms processing time.
This makes for an overall saving of about 4ms, with negligible loss in
quality.

7c2d493bb5 [client] audio: add latency tuning parameter
This adds a new `audio:bufferLatency` option which allows the user to
adjust the amount of buffering LG does over the absolute bare minimum. By
default, this is set large enough to absorb typical timing jitter from
Spice. Users may reduce this if they care more about latency than audio
quality.

This adds a new `audio:periodSize` option which defaults to 2048 frames.
For PipeWire, this controls the `PIPEWIRE_LATENCY` value. For PulseAudio,
the controls the target buffer length (`tlength`) value.

0dad9b1e76 [client] audio: fix latency calculation if audio device starts early
If the audio device starts earlier than required, we slew the read pointer
backwards to avoid underrunning. We need to apply this same offset to the
recorded device position, otherwise the Spice thread will think playback is
further ahead than it really is and inject unnecessary latency to
compensate.

d9dc399522 [client] audio/pw: request real-time priority
This is as per the PipeWire ALSA plugin [1]. The existing
`PW_STREAM_FLAG_RT_PROCESS` flag is misleading and doesn't really have
anything to do with real-time priority; it just tells PipeWire to pull data
from the application synchronously from its main processing thread. More
detail at [2].

70158a64e7 [client] audio: open device earlier
The actual time between opening the device and the device starting to pull
data can range anywhere between nearly instant and hundreds of
milliseconds. To minimise startup latency, open the device as soon as the
first playback data is received from Spice. If the device starts earlier
than required, insert a period of silence at the beginning of playback to
avoid underrunning. If it starts later, just accept the higher latency and
let the adaptive resampling deal with it.

We can set the startup latency for the next playback far more precisely if
