test for GST_VIDEO_FLAG_PREMULTIPLIED_ALPHA to/from caps

It would be nice if GST_VIDEO_FLAG_PREMULTIPLIED_ALPHA is reflected in the caps. Attached is a test case I would expect to work.

Review of attachment 372079 [details] [review]:

This flag has always only been used internally in the converter / scaler. It is really hard to add this now. Adding a new field does not work, since existing element will accept that format even if not supported (because no fields, many any/all). Do you have a plan/idea ?
Comment 2 Stian Selnes (stianse) 2018-05-15 17:19:55 UTC 
No plan, really. It was just surprising behavior so I thought I'd post a bug. I needed to pass this information when writing a test for our converter, but found an easy way around that. Feel free to close this if it's unlikely to be implemented :-)
