Is it possible to make this call in drawLayers()?

Specifically, I don't think we are going to know what surfaces have cached textures until we have given them all to the LRC and let it figure out what it can afford for the frame. And I don't think that a call to LRC belongs in here, right now I am planning to include this in LRC::beginDrawingFrame().
