It doesn't surprise me that filling with a solid color is faster than
applying a color-correction. I don't think the image map tools are
implemented particularily slow (but of course I would like to see a
faster implementation). The problem rather seems to be that the effect
is applied on the whole image instead of doing some kind of preview
that takes the viewed area and display scale into account.
