It compiles!!! woot The same drawing test, with the compiled version, took 96ms per iteration. About 25% faster than non-compiled. But the REAL enhancement is when you move around... before, a lot of stuff had to be completely redrawn; now, only the newly shown portions are redrawn, and that is for ALL layers, including LVZ's. Still a lot of bugs to squish, and a couple more things to implement, though -There are a few pixels that are not redrawn correctly when moving around -Specific tools have not been tested at all (TileText, PicToMap, things like that) -Selection edges are not drawn yet -!@#$%^&*S regions are not drawn yet I'll attach a test version soon, so you guys can try it out and maybe find some bugs.
