//
//	gint display module: screen
//
//	Interacts with the physical screen. See other display modules for video
//	ram management and drawing.
//
//	The screen basically has two input values, which are a register
//	selector and the selected register's value. What this module does is
//	essentially selecting registers by setting *selector and assigning them
//	values by setting *data.
