Description

On Linux, at least, enabling fsaa via the video options menu will result in the engine no longer drawing frames. This issue appears to persist between sessions and requires that `-nofsaa` be passed at startup in order to uncheck the appropriate option.

During the bugs effect, the engine is other perfectly operable, e.g., games can (apparently) be started and audio output can be heard.

There appears to be no complaint on stdout/err when the option is selected, but the effect is immediately apparent as graphics output will be frozen from that point onward.

I tried switching FSAA on OS X, and while it continues to render the view, there's a ton of OpenGL errors being reported in the console. Something needs fixing...

This should now be resolved thanks to the low-level OpenGL changes. FSAA is only used in the FBO where the game view is rendered; the rest of the window contents are always drawn without multisampling.
