 Abstract: ColorRect is a lightweight class for splatting a colored rectangle into a RectsView (which actually does most of the work). A ColorRect can be locked down, so that the user can't move it, in which case it draws a little X in the middle. When the selected rect is locked, the RectsView doesn't allow the user to move the ruler markers.
