Detect the single-monitor case, which we assume to be a mirrored display with a Rift. This case is indistinguishable from the "no Rift attached" case, but it will allow most users to more easily use the program.
Minimize the tweakbar on launch in the single monitor case.
On a backtick(`) press, shrink the full-screen window at [0] in g_outStreams to 1000x800, single eye view and pop the TweakBar back up.
