b35a2c1e6e Complete masked tile rendering implementation
The core data tables were reworked to pre-reverse all of the
entries to directly match the right-to-left ordering of the code
fields.  This simplified some code but was required for register
reuse in the masked tile renderer.

Also fixed several offset calculation issues in the masked tile
renderer.

90124b04bc First draft of masked tile support
Need to have the called provide a copy of the base line address to the
masked drawing code and need to verify that the JTable entries are
ordered the same way as the byte offset so the same register can be used
to load the JMP addresses and patch in the LDA (DP),y instructions.

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.
