New Tarkin performance tweaks

I revisited some of Ruida’s undocumented controller fields again and found some cause/effects that seem to really help. This new combination seems to eliminate “bounce” artifacts on certain types of corners, improve the burn power consistency in sharp corners, AND is generally faster on all detail work.

This looks notably better all the way around.

In my tests, I couldn’t find any downside to the tuning improvements, but I don’t have every possibly test case. So, please report any problems and, if at all possible, please provide the problematic project file so I can reproduce it
