--- Comment #1 from Justin Fan <justin_fan at apple.com> ---
Myles' comments:

> 1) make the WHLSL functions round-trip. So if you invoke a bunch of different constructors and then run a bunch of getters, you get the expected thing.
> 2) make the memory layout match HLSL. If you upload 16 floats in a buffer and then tell the shader that the buffer contains a matrix, the getters should also return the expected thing
