i dont like this at all, using upper/lower case to distinguish formats
following is much closer to the existing system: RGBA -> RBA[bits] ARGB -> ARB[bits] ABGR -> ABR[bits] BGRA -> BRA[bits]
This only works if all the components have the same amount of bits.
Anyway I don't mind if you want to use this scheme for the missing formats: rgb444be -> [16]BRA rgb444le -> ARB[16] bgr444be -> [16]RBA bgr444le -> ABR[16]
the bits value should be 64 for 16bit per component, 32 for 8bpc
This would lead to:
rgb444be -> [16]BGR rgb444le -> RGB[16] bgr444be -> [16]BGR bgr444le -> BGR[16]
the value should be 12, its in line with rgb15
Fixed, regards.
