 Hello,

If it could be of interest, here are new speed measurement for -l13 very
high compression setting.

For x265 (HEVC), I use BPG codec, and this time I use -m 0 setting which
uses the fastest encoding setting of x265.I run the .exe 10x times and I
pick the best scores.

So here are the timings at -l13 very high compression:

Encode time: x265 (BPG -m 0): 80ms  NHW: 20ms
Decode time: x265 (BPG): 90ms  NHW: 10ms

So with an equivalent level of optimization (x4-5, multithreading,
SIMD,...), the NHW Project is 80/20x5=20x faster to encode and 90/10x5=45x
faster to decode than x265 (optimized HEVC)!

Yes, 45x faster to decode than x265 at very high compression!, this would
really save on battery life for mobile devices!

Else also, with the new improvements I finally find the NHW Project
competitive with x265 (HEVC) on nearly 90%-95% of the images I have tested
at -l13 very high compression, because it has more neatness.

I will continue to go down to very high compression, but it is not that
easy, anyway you can have a first idea with -l13 very high compression
setting on my demo page ( http://nhwcodec.blogspot.com/ ).

Many thanks!
Cheers,
Raphael
