+* A library of functions for displaying graphics on the screen.
+* The connected LCD physical screen consists of 320 rows (indexed 0..319, top to bottom)

+* the screen is indexed (0,0). Every pixel can be set to a 16 bit color code composed of
+* RGB parts of 5 bit red, 6 bit green and 5 bit blue: rrrrrggggggbbbbb.
