Colorspaces names scheme

[Cyrille Berger]

Hi,
I have notice some problems with the way or colorspace are named, currently we 
have : RGBA, RGBA16, CMYK, CMYKA16, LABA (etc...)

Some thoughts about it :
1) CMYK should be named CMYKA
2) LABA is a 16bits channels whereas all other colorspaces without numbers are 
8bits

I suggest that in the name we allways include the depth meaning RGBA should be 
renamed RGBA8 and LABA renamed LABA16 (etc...). And we have also a difference 
between colorspaces which used unsigned (U), signed (I) or float (F), I think 
it might be a good idea to add the type of the channel then RGBA become 
RGBA8U LABA -> LABA16U etc... (I know it can become even more complicated in 
the future, when colorspaces will have different data type for each channel, 
but maybe someone will have a better idea)

any opinions ? If you agree I will do the change during next week.
