Segmentation Entropy and tweaks. Some correction for entropy impact of segment signaled (EOB and ref frame) Other slight tweaks. Derf VBR average gain now over 1% (best over 7%) One YT test clip has gains of circa 30% (VBR) There is still an issue with noisy clips where making the background static and coded with 0,0 can have a negative effect, especially at low Q. This is probably because of the loss of smoothing by fractional pixel filters. Change-Id: I7a225613c98067b96f8fc7a7e36f95d465b2b834
