Detailed Description

A control to select an RGBA color, with each mouse button corresponding to r, g, and b.

By default, pressing and dragging the left mouse button changes the red value, the middle button does the green, and the right button the blue. The message is sent when a button is released.

While pressing a mouse button down and hitting r,g,b,c,m,y, or k, will cause that button to shift the corresponding color. Internally, the colors are all rgb, and the cmyk transformations are through the simple non-icc rgb<->cmyk conversion.

This window sends SimpleColorEventData.

The box can be one of LAX_COLOR_CMYK, LAX_COLOR_RGB, LAX_COLOR_GRAY.

Todo:

would be neat to maintain a stack of previous colors?

might be nice to display number in window while dragging..

someday do a color managed version of this window

incorporate wheel movements to scroll the last accessed color
