bjorn 29cbe63b1d OpenXR: Add support for XR_FB_hand_tracking_mesh; 
This adds the ability to load and animate a mesh for hand tracking on
the Oculus Quest.  It is more or less identical to the current
functionality on the vrapi driver.

One key part of this change is that getPose in OpenXR will see if action
spaces are active before locating their spaces.  This is due to some
behavior observed on the Oculus Quest with hand tracking  where pose
actions for controllers would return invalid data with all of the
location flags erroneously set.  The only way to detect and work around
this is to check the pose action state.  When this happens, we fall back
to returning the pose of the wrist joint, which is where the Oculus hand
mesh wants to be drawn.  In the event that both controllers and hand
tracking are active, the controller pose will be returned by getPose but
the wrist joint can still be accessed using getSkeleton.

Note that this does not yet include support for properly scaling the
hand mesh.

There are numerous opportunities for optimization here that may be
investigated in the future, though performance is well within an
acceptable range right now.

bjorn 450ee72c89 OpenXR: Windows graphics plugin properly uses HDC instead of HWND;

bjorn c9fe026a66 Fix undefined behavior in arr_free; 
Currently there is a single allocator function used in arr_t.  Its
behavior depends on the values for the pointer and size arguments:

- If pointer is NULL, it should allocate new memory.
- If pointer is non-NULL and size is positive, it should resize memory.
- If size is zero, it should free memory.

All instances of arr_t use realloc for this right now.  The problem
is that realloc's behavior is undefined when the size argument is zero.
On Windows and Linux, realloc will free the pointer, but on macOS this
isn't the case.  This means that arr_t leaks memory on macOS.

It's best to not rely on undefined behavior like this, so let's instead
use a helper function that behaves the way we want.

bjorn 8462beef00 Fix/improve alpha cutoff; 
The current flag did not work because float shader flags are not
supported.  It was also not very useful because it was per-shader
and did not use the alpha cutoff property of glTF materials.

Instead, let's turn the shader flag into an enable/disable boolean,
and add a scalar material property named "alphacutoff" that gets
read by the glTF importer.

When the alphaCutoff flag is enabled, the material property will be
compared against the pixel's alpha value to decide whether it should
get discarded.

bjorn 255ecbb4d8 Fix stencil color mask; 
- When calling lovr.graphics.stencil, the color mask is initially
  disabled, and gets restored to its initial state afterwards.
- However, when it's restored, it uses lovrGraphicsSetColorMask, which
  just sets shadow state that doesn't make it all the way to GL until
  another draw is done.
- The consequence of this is that if you call .stencil and then don't do
  a draw, any clears that happen will use the old (disabled) color mask,
  preventing the color buffer from being cleared.
- The solution here is to lower the color mask change down into opengl.c
  where it can directly hit OpenGL.

bjorn 25bb12d07c Native textures don't destroy their handles; 
If a Texture is created from a handle, that means someone else created
it, so we expect them to destroy it.  We were always destroying handles,
and I guess this was usually okay because glDeleteTextures is idempotent.

However, we're seeing a crash in the Oculus driver when OVR is torn
down.  Presumably it is trying to access its swapchain textures after we
destroyed them.  Not sure why this wasn't an observable issue before,
maybe it's a new regression.  Still, it makes sense to only delete the
GL texture handle if we were the one that created it.

We don't need to check this for the renderbuffer since we always own those.

bjorn 19620c7682 wasm: Use default miniaudio buffer size. 
Audio currently stutters on the wasm build.  It is much more severe
in Chrome than in Firefox (very rare/subtle in Firefox).  miniaudio
is currently using ScriptProcessorNode, which is deprecated because
it processes audio on the main thread.  There's a new API that lets
you programmatically process audio on a thread called AudioWorklet,
but it's hella complicated.  miniaudio doesn't want to support this
because it's complicated and requires a separate JavaScript request
but it seems like it would be possible to work around using a Blob.
In the meantime, miniaudio bumps up the buffer size on WebAudio, so
let's just use that in hope that it helps.

  many frames -- they would read a full buffer instead of only the

bjorn 0bb556554d Probably work around stb_image bug that breaks zips; 
30e01f upgraded stb_image to include its 95560b commit from its #960
pull request.  This made stb_image fail more aggressively on EOF
conditions when refilling huffman buffers in deflate streams.  I think
it might be failing _too_ aggressively, though.  We are able to pad our
input compressed buffers since the zip file format is guaranteed to have
extra data at the end (for, e.g., the end of central directory record).
This appears to be sufficient to fix compressed zip archives for the
time being.  It's possible that more virtual padding needs to be added,
and it may be good to try to fix this in stb_image itself.

The falloff is the minimum distance at which inverse distance
attenuation takes place.

A non-positive value disables distance attenuation.

In the Lua API, nil can be used to disable attenuation, a boolean can be
used to enable attenuation with a default minimum distance, or a number
can be used for full control over the parameter.

bjorn 7d0dfc9cdd Sound: Ambisonic support; 
Add support for importing ambisonic WAV files and 24/32 bit PCM WAV files.

The standard ambisonic format used internally in LÖVR is ACN channel ordering with SN3D normalization.
Anything else will be converted to this form.

There are a few restrictions and assumptions:

- Only 1st order ambisonics are supported.  They need to have 4 channels.
- They can be in AMB format (Furse-Malham order/normalization), detected via WAVE_EXTENSIBLE GUID.
- Any other 4 channel file is assumed to be in "AmbiX" ACN/SN3D format.
  - It seems that most ambisonic files in the wild that claim to be AmbiX are just 4 channel WAVs without any metadata.
  - This means that non-ambisonic 4 channel WAVs could ambiguously be mistaken as ambisonic.  This is incurred as a limitation of LÖVR.
- Ambisonic files can not currently be played back.  SteamAudio currently has numerous bugs with this.
  - Perhaps it would be possible to write an ambisonic rotator/panning decoder to use as a default implementation.

mcc 9ba4037e74 LOVR_USE_OCULUS_AUDIO 
This is a large patch which adds a new Oculus Audio spatializer. Oculus Audio is slightly different from the dummy spatializer in a few ways:

    - It *must* receive fixed-size input buffers, every time, always.
    - It can only handle a fixed number of spatialized sound sources at a time.
    - It has a concept of "tails"; the spatialization of a sound can continue after the sound itself ends (eg echo).

Changes to audio.c were needed to support Oculus Audio's quirks:

    - audio.c now supports a "fixedBuffer" mode which invokes the generator/spatializer in fixed size chunks
    - Each source now has an intptr_t "memo" field that the spatializer may use to store whatever (Oculus spatializer uses this to handle the sound source limit).
    - The spatializer interface got a couple new methods: A "tail" method which returns a sound buffer after all sources are processed; and "create" and "destroy" methods that are called when a sound source is created or destroyed (Oculus spatializer uses this to populate/clear the "memo" field).

Along the way some other miscellaneous changes got made:

    - lovr.audio.getSpatializerName() returns the current spatializer
    - Spatializer init now takes in "config in" and "config out" structs (Spatializer changes fields in config out to request things, currently fixed buffer mode).
    - lovr.conf now takes t.audio.spatializer (string name of desired spatializer) and t.audio.spatializerMaxSourcesHint (Spatializers with max sources limits like Oculus will use this as the limit).
    - audio.c went back to tracking position/orientation as vectors rather than a matrix
    - A file oculus_spatializer_math_shim.h was added containing a minimal copypaste of OVR_CAPI.h from Oculus SDK to support a ovrPoseStatef the spatializer API needs. This may have license consequences but we are probably OK via a combination of fair use and the fact that a user cannot use this header file without accepting Oculus's license through other means.

Some work remains to be done, in particular there is an entire reverb feature I did not touch and LOVR_USE_OCULUS_AUDIO cannot be activated from tup. Oculus Spatializer works better when it has velocity and time information but this patch does not supply it.
