+     * 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. 
+     *     `astcenc-sse2 -cl MoreRocks.png MoreRocks.l-4x4-100.astc 4x4 100`
+     * 
+     * Step 2. Decompress the data we just created. 
+     *     `astcenc-sse2 -dl MoreRocks.l-4x4-100.astc MoreRocks.l-4x4-100.astc.png`
+     *     
+     * Step 3. 
+     *     I used convertio to convert the PNG generated in step 2 to create MorRocks.l-4x4-100.astc.rgba
+     
+     * WHAT WE DO IN THE TEST BELOW:
+     * 1. Read the sample image, ASTC-compressed reference, and decompressed reference that we generated above.
+     * 2. Run TryDecodeToRgba8P on our ASTC-compressed texture.
+     * 2a. Write the output of step 2 to the disk.
+     * 3. Assert that the data we decompressed in our method is the same data as the decompressed reference image.
