See e.g. http://searchfox.org/mozilla-central/rev/02a56df6474a97cf84d94bbcfaa126979970905d/gfx/layers/client/ClientLayerManager.cpp#524 - there's a stack of code stretching from nsGlobalWindow to the compositor to do with compositor overfill ratios that looks unused. I think at least some of it was added for b2g back in bug 979949, so should be safe to remove.

I don't think this qualifies as a feature, it's just dead code removal.
