// Revision 1.15 1996/02/29 22:55:40 hr
// The colormap editor doesn't clean up after itself when deleted. Can't
// use the dummy editor until it does.
//
// Revision 1.14 1996/02/29 17:09:23 hr
// The XPalette is now only ref'ed once rather than for each window.
// Added code to initialize to preallocate the colormap editor's colors.
//
// Revision 1.13 1996/02/28 21:22:44 hr
// initialize was calling initializePGColormappings more than once.
//
// Revision 1.12 1996/02/01 21:44:45 hr
// Added support for button specific creation parameter to allow creating
// toggle buttons in the on state.
//
// Revision 1.11 1996/01/24 17:53:19 hr
// Added call to initializePGColormappings.
//
// Revision 1.10 1995/10/26 14:02:40 baker
// Changed hide and show to refer to the parent class.
//
// Revision 1.9 1995/10/23 17:20:39 hr
// In function initializeTop, strip any leading pathname component before

//
// Revision 1.8 1995/10/10 23:18:46 baker
// General cleanup.
//
// Revision 1.7 1995/10/06 23:56:03 baker

// Release Beta 1.0
//
// Revision 1.5 1995/04/06 20:52:54 hr
// ~AvApp was unrefing the palette, but it was only being ref'd during
// palette creation.
//
// Revision 1.4 1995/03/30 22:20:01 hr
// Removed tear off menu support since it caused crashes on
// Solaris (at least) systems.
//
// Revision 1.3 1995/03/29 18:22:05 pixton
// Inserted mini-event loop to allow the file selection box to
// disappear as soon as OK is pressed.
//
// Added filter to prevent continueProc_ from being called when
