Adding API for signed BC4/BC5 variants

Open PredatorCZ opened this issue 2 years ago • 0 comments

With recent addition of BC4/5, I've decided to add signed variants as well. BC5S is great for normal maps, saving 2 shader instructions. I don't have any use for BC4S but I added it anyway since it shares the same code.
