Fixed an editor bug where, if you placed an enemy gate, then placed some enemies, then deleted the enemies, the gate would open and would never close again.
Fixed a bug where, if the last diamond in the level disappeared by being overwritten by a copier, the diamond gates would show zero but not open.
Fixed a design bug in level 6/4 that let you skip a puzzle.
Graphical Changes:
Reduced the prominence of dark spots in the soil texture that could look like holes even though it's just normal ground you can drive over.
Added an option to turn on Triple Buffering.
Added an option to use multi-threaded rendering.
New Editor Stuff:
Added the item from one of the very secret levels that turns you into a bullet. It's unlocked if you've beaten that level.
If you've beaten the other very secret level, this now unlocks another item in the editor. It's not something that appears in the level, or in the game at all, it's just something I thought might be fun.
Mac-Specific Changes:
Removed OpenGL support.
Blackshift now declares itself a game, so MacOS will run it in Game Mode.
