Comment #3 on issue 450 by alexandre.bergel: Non embedded edges culling in Mondrian http://code.google.com/p/moose-technology/issues/detail?id=450 I did some benchmark, but I am not sure on how close they are to the reality. I generated the blueprint of the AST classes. Doing 100 repaints of take 9214 ms without the improvement. It takes 6045 with. To obtain the canvas, I put a "self haltOnce" in MORoot>>displayOn:
