/****************************************************************\
* Main client painting routine
*--------------------------------------------------------------
*
* Name: MainPaint(hwnd)
*
* Purpose: Paints the main client window.
*
* Usage: Routine is called whenver the client window
* procedure receives a WM_PAINT message
*
* Method:
* - begins painting by calling WinBeginPaint
* and retrieving the HPS for the window
* - performs any painting desired
* - ends painting by calling WinEndPaint
*
* Returns:
*
