I haven't noticed any either, I think I've fixed almost all of them.

There is an occasional lowering of quality in the anti-aliased areas but 
it is subtle.

Your timings seem a bit strange, but I get up to 5-10 times improvement 
in some areas.  The actual improvement will vary by machine and depends 
on your software renderer and cpu speed (for unaccelerated computers).

I may well make some more improvements (dice rolls and speeding up point 
making+bearing off).
