/**
*
* NOTES
*
* HOW I GENERATED INPUT DATA
* Step 1. Create ASTC-compressed image from sample data.
* *** NOTE This image isn't 2^x evenly sized, it's 768x512 - something that would break down into nice squares, for sure.
* `bin/astcenc-avx2 -cl sources/kodim01.png output/kodim01.l4x4.astc 4x4 -fast`
*
* Step 2. Decompress the data we just created.
* `bin/astcenc-avx2 -dl output/kodim01.l4x4.astc output/kodim01.l4x4.astc.png`
*
* WHAT WE DO IN THE TEST BELOW:
* 1. Read the sample iamge, ASTC-compressed reference, and decompressed reference that we generated above.
* 2. Run TryDecodeToRgba8P on our ASTC-compressed texture.
* 3. Assert that the data we decompressed in our method is the same data as the decompressed reference image.
