High quality compressed color texture format.
BC7 format compresses textures to 8 bits per pixel, and is supported on DX11-class PC hardware, as well as PS4 and XboxOne.
Generally it produces better quality than the more widely available DXT5 format, however it requires a modern GPU, and texture compression during import time is often slower too. Note that BC7 is not available on Mac when using OpenGL.
When loading BC7 textures on a platform that does not support it, the texture will be decompressed into RGBA32 format (32 bits per pixel) at load time.
