bitBlt in KoLCMSColorSpaceTrait

[Boudewijn Rempt]

Just answering a question Cyrille asked on irc just when I was heading for 
bed:

bitBlt is implemented in KoLCMSColorSpaceTrait because that's where, 
historically, the conversion between colorspaces during bitBlt was 
implemented, when it was still KisAbstractColorSpace. The reason for that is 
that it tried to first convert through lcms, and only in the second instance 
through to/fromQColor.

Better would be, I think, to have conversion through formula's or 
to/fromQColor in KoColorSpace (which would then cease to be a pure abstract 
virtual interface) and override that in KoLCMSColorSpaceTrait with conversion 
through lcms.
