skydarc 2:2946f9eefcae 2 This is the core graphics library for all our displays, providing a common
skydarc 2:2946f9eefcae 3 set of graphics primitives (points, lines, circles, etc.). It needs to be
skydarc 2:2946f9eefcae 4 paired with a hardware-specific library for each display device we carry
skydarc 2:2946f9eefcae 5 (to handle the lower-level functions).
