Jaguar text layer

I completed the Jaguar version of the text layer. I tied it into the object/sprite system. One of oddities that I found is that sprites drawn at 8 pixels high repeat the last row of data. If they are 9 pixels high they work perfectly. I think this is documented in the official documents. Outside of the Sega CD and Neo Geo CD, this has been the easist text layer to implement. And, the Sega CD and Neo Geo CD have hardware to support this.
