This greatly speeds up running all the conformance tests by no longer delaying many of the tests for a number of dummy frames to be painted. We used to skip frames because we thought there was a problem with the driver's glReadPixels implementation. Although we have seen driver issues at times the real reason the delay was needed was because resizing the stage usually happens asynchronously (because a non synchronous X request is used by clutter_stage_set_size()). We now force all X requests to be synchronized for the conformance tests so this is no longer a problem and we can avoid these hacks.
