Changes between Initial Version and Version 1 of Ticket #1423, comment 2

initial	v1
12	12
13	13
14		Ready for testing: the jpeg decoder and encoder should now be faster. BUT, we were previously always using YUV420P with the pillow based encoder whereas now we choose the pixel subsampling based on the quality setting. So this may actually be '''slower''' at higher quality settings.

So this may actually be '''slower''' at higher quality settings. (the opengl backend should paint more quickly as it paints using YUV directly, this may also affect the html5 client.. we may want to lower / adjust the jpeg quality settings for it)
