* Exchange one color with the other (settable threshold to convert from

*
* Author: robert@experimental.net
*
* Added ability to select "from" color by clicking on the preview image.
* As a side effect, clicking twice on the same spot reverses the action,
* i.e. you can click once, see the result, and click again to revert.
*
* Also changed update policies for all sliders to delayed. On a slow machine
* the algorithm really chewes up CPU time.
