Rewrite time. Again.

After being unsatisfied with a previous incarnation, I decided to rewrite Figure Studio yet again. This time, I’m switching from DirectX using SlimDX to OpenGL using OpenTK. The current incarnation of the source can be found on its GitHub page. Unless you can find a drop-in replacement for the Microsoft Scripting engine, it probably won’t be possible to do a 100% port to other platforms.
