Instance buffer layout is incorrect under WASM #7
Description
- Instances draw, but with incorrect positions
- Instance buffer appears to be excessively padded
- Manually drawing instances 0..64 for each indirect reveals that all the transform data is there,
but at unexpectedly wide intervals instead of the expected 1-instance-wide - Experimented with explicitly specifying struct size and alignment, but makes no difference
- Likely some unaccounted-for wgpu limit
