PixelPaint: Editing mask optimization

Browse source 
This patch introduces a new function "Layer::editin_mask_bounding_rect"
that is used within the LevelsDialog, Luminosity and Colormasking to
process only the area where a mask was applied. Therefore we can
greatly reduce the amount of processed pixels if only a small portion
of the image was masked.
