Avoid readback with Web
GL and d3d compositors
We currently do readback to render WebGL on Windows. Since we are using ANGLE, we might be able to avoid that. See discussion in https://bugzilla.mozilla.org/show_bug.cgi?id=874721#c51 and previous comments.
Something like this for MTC: http://mxr.mozilla.org/mozilla-central/source/gfx/layers/d3d10/CanvasLayerD3D10.cpp#27
Need to add d3d versions to http://mxr.mozilla.org/mozilla-central/source/gfx/layers/client/ClientCanvasLayer.cpp#24
