btw, there is an open issue on mantis for the NewColorPicker
http://bugs.squeak.org/view.php?id=7753
NewColorPickerMorph can not be used to change colors re erase
colors from a SketchMorph.
The Menu entries
"erase pixels of color" and
"recolor pixels of color" raise a DNU.

Changing a GradientFill color from within the
fill style menu (for any morph) doesn't work as well.
