known issues:
- negotiation is shite. I don't want to know about any failed
negotiations or failed prerolls.
- teardown sometimes fails.
- sharing a GL context among a bunch of elements that stomp all
over it is potential fail.
intel driver:
- rendering to texture ignores the color matrix. This causes any
YUV->RGB conversion to fail.
- YUY2 and UYVY conversions in the driver use the wrong matrix.
