Bug 865033 broke mozmill OS X tests on Thunderbird (https://tbpl.mozilla.org/php/getParsedLog.php?id=31749252&tree=Thunderbird-Trunk):
Assertion failure: compositor (Passed invalid backend hint), at ../../../../mozilla/gfx/layers/ipc/CompositorParent.cpp:731
Turns out we pass LAYERS_NONE when we don't have a basic compositor, so we need to handle that case here.

I hit this assertion in Firefox too, if I set:
  user_pref("layers.acceleration.disabled", true);
