e4c6dcf3bc more efficient depth mipmaping 
We simply pick one of the 4 depth texel based on its screen
space offset. Literature showed it doesn't impact AO
significantly.

53adfedc83 Fix msan use-of-uninitialized-value in destroyVertexBuffer (#1277) 
GLVertexBuffer.gl.buffers is a std::array which is not
default-initialized, and createVertexBuffer only initializes the first
bufferCount fields of the array.

When destructing, destroyVertexBuffer iterated over all buffers to unset
bindings, but it was erroneously iterating over the entire array instead
of the initialized values.  Update the loop to only iterate over known
initialized values.

f441e4ec4e Switch desktop to interleaved RGB noise (#1263) 
This eliminates the flicker caused by triangle noise based dithering
when FXAA is turned on. This will require further investigation to
see if we can use triangle noise with FXAA without such artifacts.

475cd80faf gltfio: consolidate buffer slots. 
Instead of using the actual glTF attribute indices, we now pack them
so that unused indices do not take up any VertexBuffer slots.

Fixes #1256.

37ff2d903f Additional validation in VertexBuffer::Builder::build. 
If a client asks for more than 8 buffers in a VertexBuffer, they will
either crash (release) or hit an assert in OpenGLDriver (debug). It's
better to catch this earlier.

This was noticed while investigating #1256.

ce4a3edf7b gltf_baker: visualizers now use fp32 textures. 
This allows us to skip the CPU-side vector-to-color conversion that
occured at the end, and makes the real-time visualization consistent
with the final visualization.

There was typo that prevented the ashmem fallback code to work.
This became briefly a problem on Android Q before we fixed our
use of private APIs.

This change also fixes a sorting issue: different sorting modes
were sorted in different buckets which is incorrect. We want
to sort only by distance.
