I'm looking for a way to select "transparent" or "none" as an option in the color palette.
Ideally this would be a box that is the width of the palette with the text "No color" at the top. A "getColor" would return a special value (as either null, blank or a special 'transparent' value). I'd be using it from a ColorMenu ultimately.
Before I dig in, has anyone already implemented this capability? Is this something that would make a good enhancement to the base library?
If not, I'd really appreciate any tips on how to go about extending the ColorPalette or ColorMenu in this way.
