<pre>So, this demo has several problems:
- Not enough memory allocated in a pool which ends up by crashing with RADV. It
does work with AMDVLK because they always allocate more space than needed. I
pushed a change for that this week, but it was actually wrong and has been
reverted. So, expect a crash anyway.
- Use of 16-bit integers without checking if shaderInt16 is supported.
- Possibly a missing barrier which might explain the rendering glitches on GFX8
(syncing GFX shaders and invalidating L2 seems to fix the problem).
Tangrams is buggy in many ways and I don't think it's worth trying to
investigate more.</pre>
