 * This is a service providing generic implementations of graphic primitives
 * - Horizontal line
 * - Vertical line
 * - Line
 * - Circle (filled/not filled)
 * - Rectangle (filled/not filled)
 *
 * it also provides functionality to draw a bitmap to the graphic memory.
 *
 * These functions are made available if the graphic hardware being used do
 * not implement the functionality in hardware. This is true in most cases.
 *
 * This service is included as a requirement for a
 * hardware specific component that uses these functions, and provides a
