-        e.g. x==3.5, round(x) == 4. However, our state is working with the
-        inverse matrix, and so to match the result of "normal" rounding, we
-        subtract 1 so that we in effect behave the same at the half-way point.
-        To compare, try drawing a bitmap with y == exact-half using the sprite
-        blitters and with us. Without the -1, we will draw the colors a whole
-        pixel shifted up (yikes).
