Hi PaQ, cool smoke test!

re: Transformation speed instead of display speed - that is an area that I can more easily improve.

Currently it creates a complete copied object for every transformation result, and especially mirror does a bunch of work that tends to make it slow on larger objects.

It should be possible for me to improve this quite a bit to kind of redraw the existing object during the dynamic part of transformations instead of making actual duplicates until you are finished.
