 On tabbing we are currently auto-toggling the frame.  Are we sure that
 this is necessary?  Could we include a configuration option to change
 this?

 Drawing the frame animation during tabbing robs us of processor right when
 we need it, slowing the perceived transition time between windows.
 Furthermore, as the XO only has one processor the frame animation (which
 requires available processor to run smoothly) will skip a lot of frames if
 the processor is loaded.  As we're auto-saving and re-rendering the
 windows of every window we pass during tabbing, the processor is
 invariably quite loaded, and the frame draw consequently is quite clunky.
