Daniel, if you are working on this, could you have a look into backporting 
the paint-to-fbo stuff here 
http://bazaar.launchpad.net/~linaro-graphics-wg/compiz-core/linaro-gles2-update/view/head:/plugins/opengl/src/screen.cpp#L1519

There's very little performance penalty here since there is only one 
pipeline flush and it has the added benefit of reducing complexity in merging
the linaro branch in a few weeks.
