 * 
 * *****************  Version 2  *****************
 * User: Anna         Date: 13/12/02   Time: 23:04
 * Updated in $/Projects/Libraries/CJLibrary/CJLibrary
 * CCJColorPicker is now theme aware
 * 
 *
 * *****************  Version 5  *****************
 * User: Kirk Stowell Date: 10/31/99   Time: 11:49p
 * Updated in $/CodeJock/CJLibrary
 * Overrode OnEraseBkgnd(...), OnPaint() and made modifications to
 * DrawItem(...) for flicker free drawing.
 * 
 * Modified resource include for static builds.
 * 
 * Added method CheckTextColor(...) which tests if the intensity of the
 * color is greater as 128. If the intensity < 128 => color is dark, so
 * the text must be light. Stephane Routelous
 * [routelous@cad-cam-concept.de]
 * 
 * Fixed potential resource and memory leak problems.
 * 
 * Removed un-necessary calls to GetParent(), a call is made only once at
 * initialization, to ensure we are working with a valid handle.
 * 
 * Made class methods virtual for inheritance purposes.
 * 
 * *****************  Version 4  *****************
 * User: Kirk Stowell Date: 10/14/99   Time: 12:22p
 * Updated in $/CodeJock/CJLibrary
 * Added source control history to file header.
