//	Button Functions
//
//	These functions create buttons from graphics that can change as the mouse moves over
//	them.  The name of the button is used as the name of the file with 1.gif,2.gif, or 3.gif
//	added.
//
//	The buttons can be organized into radio groups using the Button_DoSet() function
//
//	1 - normal image
//	2 - mouse over image
//	3 - tool selected image
//
//***************************************************************************************
