e3cb742626 Fix tile rendering 
This is not quite correct yet.  IT appears that two rows or columns are
drawn on the edges when only a single solumn or row is necessary.  Also,
this code is based on the old GTE codebase, so the initial rectangle for
rendering tiles is width+1, height+1. This can be improved.
