// See bug 630197 - we have some reasons to believe if an earlier call
// returned an error, the upcoming present call may raise an exception.
// This will check if any of the calls done recently has returned an error
// and bails on composition. On the -next- frame we will then abandon
// hardware acceleration from gfxWindowsPlatform::VerifyD2DDevice.
// This might not be the 'optimal' solution but it will help us assert
// whether our thoughts of the causes of the issues are correct.
