Graphical display system

This service provides an interface to drawing graphics on a graphical display.

The graphics service consists of the following:

The display driver interface provides an general interface to be used by the application or by libraries.

The generic drawing primitives is a library of functions for drawing graphics primitives such as lines, rectangles and circles. It uses other functions implemented by the display driver for drawing the primitives. The implementation of these functions can optionally be used by a display driver, but if the hardware of the display allows faster handling of any of the primitives, the display driver can implement it directly.

The display specific drivers provides an interface to the graphical display via the display controller. It implements the low level communication with the display hardware, putting pixels on the display and drawing primitives such as lines, circles and rectangles. Depending on the display driver implementation, drawing the graphics primitives might be handled by the generic graphics drawing primitives rather than the display driver itself.
