		int &	actual_delta_y
	)

Move the eye (and the fovea with it) by the given delta X and Y. Set the output values to that actual delta moved, which can be less if hitting the edge screen, which allows for the full fovea to still be within the screen boundaries.

delta_x	The requested move delta X.
delta_y	The requested move delta Y.
actual_delta_x	Set this to the actual delta X moved.
actual_delta_y	Set this to the actual delta Y moved.
