 Mask specifies the bits that are to be manipulated, and Offset contains the new
 values for these bits, ie. texture X/Y coordinates are adjusted as so:<br/>

 The area within a texture window is repeated throughout the texture page. The
 data is not actually stored all over the texture page but the GPU reads the
