Hi all, I've just rolled out an update to fix a few issues and add some requested features.

• Updated OpenGL initialization of render target textures. These now get zeroed out by default, and depth-stencil attachments have been altered to improve framebuffer completeness/validity. This change is intended to address rendering glitches seen on some Mac and Linux configurations. I can't guarantee it'll work for everyone or that it won't break anything else, but it should be an improvement.
• Added toggles for inverted axes and texture distortion.
• Fixed a location in the world where the player could get stuck.
• Added a Mac icon set.
