// Steve Tchuinte:
// this is a somewhat cleaned up version of the original GLCD.c file
// that comes inside the Example/GLCD.rar archive on the DVD shipped
// with the LandTiger 2.0 board;
// cleaning consists mainly in commenting out portions that turned
// out to be unecessary for my particular board instance; initial version
// would not be linked by the MDK lite edition...
//
// for my own reference, here is what the header of the original file contained:
