<description>
- Decompresses the image if it is compressed. Returns an error if decompress function is not available.
+ Decompresses the image if it is VRAM compressed in a supported format. Returns [constant OK] if the format is supported, otherwise [constant ERR_UNAVAILABLE].
+ [b]Note:[/b] The following formats can be decompressed: DXT, RGTC, BPTC, PVRTC1. The formats ETC1 and ETC2 are not supported.
