6.5.1 Tiling
Tiling reads the pixel color from the correlated tiling pattern and maps it onto
the polygon. The tiling pixel is determined by the coordinate of the correlated
pixel irrespective of the primitive position and size. Since the tiling pattern is
stored in the internal texture buffer, this function and texture mapping
cannot be used at the same time. Also, the tiling pattern size is limited to
within 64 x 64 pixels.
