TransformableTileLayer

Implements a modified TileLayer with transformability with capabilities similar to MODE7. <br/> Transform function: [x',y'] = ([A,B,C,D] * ([x,y] + [sX,sY] - [x_0,y_0])>>>8 + [x_0,y_0] <br/> All basic transform values are integer based, 256 equals with 1.0 <br/> Restrictions compared to standard TileLayer: <ul> <li>Only a single type of bitmap can be used and 4 bit ones are excluded.</li> <li>8 bit tiles will share the same palette.</li> <li>Tiles must have any of the following sizes: 8, 16, 32, 64.</li> <li>Maximum layer size in pixels are restricted to 65536*65536</li> </ul> HDMA emulation supported through delegate hBlankInterrupt.
