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