Make textoverlay negotiate caps more correctly. 1) Check what caps we received in the video-sink 2) If it already has the overlay meta -> use it directly 3) If it doesn't, textoverlay try adding the overlay meta and using it, if downstream doesn't support it, just use what is received in the video-sink 4) Check if the allocation query also supports the meta to enable really using it Before it wasn't really doing renegotiation of any kind, just re-checking if it should use the overlay meta or not Also had to update the caps in the test as memory:SystemMemory seems to be required when you use a caps feature otherwise intersection/subset checks will fail. https://bugzilla.gnome.org/show_bug.cgi?id=733916
