* Function: WinMain()
*
* Description:
* This is the main window function and we use it to initialize data
* and then call our loop function. This is a std. Win32 function.
*
* Args:
* HINSTANCE hInstance // handle to current instance
* HINSTANCE hPrevInstance // handle to previous instance
* LPSTR lpszCmdLine // pointer to command line
* int nCmdShow // show state of window
*
* Return Value:
* int Returns the return value of DispatchLoopNT
