 To fill the screen: X1=0, Y1=0, X2=255, Y2=191
 
 Note that coordinate (0, 0) is the bottom-left corner of the screen, while ht is
 the upper-left corner of the screen in the 2D graphics engine.

 When a polygon is too small or too far away it is reduced to a single pixel on
 the screen. This register will determine the cutoff distance that the 3D engine
 will use to determine whether to render them or not.
