 * Added comments and cleaned up code.
 * 
 * *****************  Version 3  *****************
 * User: Kirk Stowell Date: 3/13/99    Time: 4:24p
 * Updated in $/CodeJockey/Include
 * Patrick Bergeron [patb@softimage.com] fixed the following bugs:
 * 
 * Moving the cursor over the flat button doesn't raise the button right
 * away. We have to wait for the first timer message to arrive, which is a
 * bit annoying. It gives the impression that the system isn't very
 * responsive. So in the OnMouseMove method, we call OnTimer(1) to force
 * the initial update of the button.
 * 
 * Sometimes, a CJFlatButton would stay in a raised state when moving the
 * mouse quickly over the client area of a few CJFlatButtons. The reason
 * turned out to be the use of a static (ahem, global) variable
 * "bPainted". The simple fix for this was to put bPainted as a member
 * variable ("m_bPainted") and use this member variable instead.
 * 
 * Flat buttons are now much more responsive and behave correctly in all
 * cases.
 * 
 * *****************  Version 2  *****************
 * User: Kirk Stowell Date: 10/17/98   Time: 4:24p
 * Updated in $/CodeJockey/Include
 * Code clean up and re-organization, renamed CCJButton to CCJFlatButton.
 * 
 * *****************  Version 1  *****************
 * User: Kirk Stowell Date: 10/17/98   Time: 4:23p
 * Created in $/CodeJockey/Include
 * Initial re-write and release.
