Decoding of Non Multiple of 4 Resolutions about hap HOT 2 CLOSED

No extra step. This is detailed in the specification, which is referenced from the Hap spec:
https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_texture_compression_s3tc.txt

from hap.

As a side note, please notice that it's true for OpenGL 2.0+ (which I suppose every player nowadays is supporting), but DirectX requires a multiple of 4 .

So it should still be recommended to have a multiple of 4 from the beginning to enable gpu decoding without extra steps if you play on window.

As a side note codec wise exporter should likely export with multiple of 4 anyway, and maybe add a flag to report that (like many codecs if you try to export 2323 resolution would pad to 2424)
