Re: [webrtc-svc] Do we need an L1T1 scalability mode? (#48)

My thoughts.....

1 - Yes, it should be returned in scalabilityModes. It resolves the ambiguity between [] as "I support everything" and [] as "I support nothing" - in this case, [L1T1] means "I support nothing, but understand what you asked, whereas [] means "I support everything", and <member not present> means "I don't understand scalability". (I'm not sure it is friendly to distinguish between empty list and member-not-present, though....)

2 - Yes, it should be a valid scalability mode in setParameters. When you don't set scalability mode in setParameters, Chrome will currently do L1T2 for VP8, I believe.

3 - Yes, this distinguishes between "I don't understand scalability modes" and "I understand scalability modes, but scalability is off".
