[Gimp-developer] LCMS 2.8 will handle alpha channels

[Elle Stone <ellestone ninedegreesbelow com>]

The LCMS 2.8 release candidate 1 has code for handling alpha channels 
during ICC profile conversions:

"2.8 does support alpha channel transportation and a new transform 
stride function and plug-in which can be used to increase significantly 
the processing speed."

Perhaps this new code could be useful for helping GIMP make faster ICC 
profile conversions? As there are a lot of profile conversions going on 
with some of the new color management code, probably every little bit helps.
