If you tell an instance of NSBitmapImageRep to init with data planes
etc. a 32 bpp image using a color space of NSDeviceRGBColorSpace, it
normally expects image data in RGBA order. I have 0RGB data. Right
now I'm munging the data into RGBA before creating an
NSBitmapImageRep, but I think I'm probably doing a bit too much work.
(I also haven't optimized it for AltiVec, so it's relatively slow.)
Is there a color space constant I can pass that will let
NSBitmapImageRep know my data is in 0RGB order, and let it do the
conversion itself? Or is there some other mechanism I should use?
