2014-12-03	Enable non-rd mode coding on key frame, for speed 6.	Marco
	For key frame at speed 6: enable the non-rd mode selection in speed setting and use the (non-rd) variance_based partition. Adjust some logic/thresholds in variance partition selection for key frame only (no change to delta frames), mainly to bias to selecting smaller prediction blocks, and also set max tx size of 16x16. Loss in key frame quality (~0.6-0.7dB) compared to rd coding, but speeds up key frame encoding by at least 6x. Average PNSR/SSIM metrics over RTC clips go down by ~1-2% for speed 6.

2014-10-07	experimental : partition using 1/8 x 1/8 image	Jim Bankoski
	The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.
