Torstennator 8c681a1603 PixelPaint: Add color-masking for editing masks
This patch adds the ability to refine a editing mask by a color-range
based on the pixels of the content image. This is useful for image
editing where mask restirction via luminosity might not fit or just
certain color ranges should be edited.
