> WISH: It would be really nice to be able to rotate the gamut mask around the center point. Then the user can use the predefined masks (like Complementary or Atmospheric_Triad) without any changes. Just rotate them to cover the needed colors and start painting :)

# How should the mask be rotated? With a keyboard/mouse shortcut like Shift+drag (regular drag is already used in the selectors)? Should there be way (an icon?) to lock/unlock the rotation?
# Persistence of the changes. The rotation angle could be saved into the kra file along with the mask (not yet implemented).
