Xpra: Ticket #437: opencl improvements, ie: no float

After testing on both GPU and CPU, it seems that using ints instead of floats can give a 50% performance boost for CPU - and interestingly, absolutely zero for GPU. It might be worth doing anyway sometime, patch attached. There are probably other performance improvements we could make.

done in r4425 - only tested RGB to YUV (not the other way around).

Gains are between 0% (Intel SDK with AMD CPU) to 50% (AMD SDK with AMD GPU at 420P) - the wiki/CSC will need updating...
