- * https://github.com/Themaister/Granite/blob/master/assets/shaders/decode/eac.comp
- *
- * With some differences:
- * - Use the vk format to do all the settings.
- * - Combine the ETC2 and EAC shaders.
- * - Since we combined the above, reuse the function for the ETC2 A8 component.
- * - the EAC shader doesn't do SNORM correctly, so this has that fixed.
