With the Reverb G2 controllers connected to the Linux host system via
Bluetooth the following segmentation fault occurs for me when starting
SteamVR with the SteamVR-Monado plugin installed:
```
$ gdb ...
...
(gdb) bt

959 if (m_xdev->hand_tracking_supported && m_skeletal_input_control.control_handle) {
960 vr::VRBoneTransform_t bone_transforms[OPENVR_BONE_COUNT];
961
962 timepoint_ns now_ns = os_monotonic_get_ns();
963 struct xrt_hand_joint_set out_joint_set_value;
964 uint64_t out_timestamp_ns;
965
966 m_xdev->get_hand_tracking(m_xdev,
967 m_hand == XRT_HAND_LEFT ? XRT_INPUT_GENERIC_HAND_TRACKING_LEFT
968 : XRT_INPUT_GENERIC_HAND_TRACKING_RIGHT,
969 now_ns, &out_joint_set_value, &out_timestamp_ns);
```
This happens because the "m_xdev->hand_tracking_supported" flag is set
but m_xdev->get_hand_tracking() is not implemented for WMR controllers.
Fixing this crash by setting hand_tracking_supported to false for
WMR controllers for now until get_hand_tracking() is implemented.

The swapchain code was creating a whole bunch of samplers, two for each image.
The thought was that samplers might depend on format, but this was not the
case. So just add a few common ones on the render_resources structs and use
them everywhere. Also fixes the bleeding distortion problem.
The type "uint" doesn't seem to exist on some platforms at least
(for example alpine linux), and it's only used in a single file,
so it seems like a good idea to change the two uses to "uint32_t".
Closes#258
This is due to the use of `${SDL2_LIBRARIES}` over `SDL2::SDL2`.
On some 'old' OSes such as Ubuntu 20.04, the SDL2 CMake config does
not set an SDL2:SDL2 target but rather defines SDL2_LIBRARIES and
SDL2_INCLUDE_DIRS variables.
This patch creates an SDL2::SDL2 target, if not already set, based on
those 2 variables.
Fix the following warning:
sdl_program.cpp(25): warning C4566: character represented by universal-character-name '\u2603' cannot be represented in the current code page (1252)
We would leak frame_id and active_wait_frames increment that would cause bad
states where we hadn't fully waited but would allow xrBeginFrame to complete.
Also improve error handling so that on error conditions the semaphore is
properly decremented and the application can call xrWaitFrame again.
This was caused by unreal doing something like this:
* xrBeginFrame <-- Error
* xrWaitFrame
* xrBeginFrame
* xrEndFrame
* Called at the same time:
* xrWaitFrame
* xrBeginFrame <-- Would get state from non-completed xrWaitFrame
Switch the device name and input/binding mappings for
Odyssey+ controllers to differentiate them from OG WMR
controllers, allowing applications to load the correct
controller model
Add a 100ms timeout for firmware reads from the HMD,
and error out if it takes longer. Fixes problems
sometimes waiting forever on my G2 when it gets
into a bad state.
Add macros for logging hexdumps of memory blocks to help
with driver development. Only macros for trace and debug
level logging are provided, as noone should be logging
hexdumps except for development.
Reuse MonadoView when "Display over other apps" is enabled. Move surface
creation logic to compositor for consistency. With this approach, compositor
implementer controls the way surface is created.
In its original call location, this diagnostic/warning function gets
called for each composition cycle even for client frames which have
not yet been delivered for display, because the frames target display
time "XrFrameEndInfo frameEndInfo.displayTime" (as provided by the
OpenXR client) has not been reached yet. Iow. if a OpenXR client
specifies a target frameEndInfo.displayTime in the future, to request
frame presentation in the future, this will cause a flood of false
"Frame late ..." messages by the compositor, despite nothing being
wrong with the timing, until the frame is actually delivered.
E.g., if frameEndInfo.displayTime is 1 second in the future, we'll
get this for each client xrEndFrame() invocation:
WARN [log_frame_time_diff] Frame late by 11.11ms!
WARN [log_frame_time_diff] Frame late by 22.22ms!
... another 87 like these ...
WARN [log_frame_time_diff] Frame late by 988.43ms!
I think what we want is to only check client frames that are actually
delivered the first time by multi_compositor_deliver_any_frames() for
initial display in the current compositor work cycle, and then report
if this first frame display onset was not on or close to the OpenXR
client requested frameEndInfo.displayTime, but too early or too late,
in violation of the clients wishes.
Moving the call check and call of log_frame_time_diff() achieves this
and gives meaningful debug output.

This allows to use the metrics logging in "streaming mode" where
records are written out with low delay, e.g., into a Unix fifo
file / pipe for live consumption by some tracing or recording
application.
XRT_METRICS_EARLY_FLUSH=true enables this "streaming mode".

Does not do anything yet within Monado, but documents how to parse
button state of left headphone volume up/down buttons and right
headphone microphone mute button.
