Bug 768952 - Select by color works correctly only in srgb 

Separate clearing/creating the image's cached color transforms from
clearing/creating its color profile. Clear the transforms when the
color profile changes, and when image type or precision change. Create
the transforms only on demand, so clearing them multiple times doesn't
trigger any redundant (and expensive) transform creations.
