amouroug 0:1cac1d87cd89 2 This is the core graphics library for all our displays, providing a common
amouroug 0:1cac1d87cd89 3 set of graphics primitives (points, lines, circles, etc.). It needs to be
amouroug 0:1cac1d87cd89 4 paired with a hardware-specific library for each display device we carry
amouroug 0:1cac1d87cd89 5 (to handle the lower-level functions).
