Detailed Description

A thread to control the psycho display from an external controller.

This class is to be used by a StimController to to control the SDL display. Display commands are read through a shared buffer. Calling programs should no longer try to handle display themselves, but merely call the setBackground() to 'inject' the calling programs image into the DisplayController thread. The image will be rendered on the next display cycle in the background of the DisplayControllers current drawing instructions.
