 *
 * This module provides read/write from and to a framebuffer in RAM. This is
 * needed when using a controller that does not provide a way to read back data
 * from the LCD controller memory. In this case we need to buffer the data in
 * a local framebuffer to allow manipulation on pixel level. It is generally
 * not recommended to access the framebuffer directy; this is handled by the
 * graphic driver when needed.
