Subject: [PATCH 1/3] main: Reload theme on loss of graphics context

The theme machinery uses FBOs in some cases (mainly for shadows) which
need to be reloaded if we get a GL context lost error.

Subject: [PATCH 2/3] screenShield: Stop using an offscreen buffer for the

extra hoops to handle here which isn't worth it.
