OptionalcolorCOLOR bits. Defaults to 8 (lossless for byte colors).
OptionalnormalNORMAL bits. Defaults to 10.
OptionalpositionPOSITION bits. Defaults to 14.
OptionaltexThe same as DracoQuantizationBits.uv, which wins when both are set.
OptionaluvTEX_COORD bits, over the UVs' range. Defaults to 16.
Per-attribute Draco quantization bits: fewer bits compress smaller, at coarser values.
