I'm back, after two weeks pure work and nothing of dolphin, take a look at the code and discover this very small fix, apply color clamping before alpha test, the way is done in the software plugin, have some nice effects, this will fix some things and brake others but the feedback is needed.

if you want to know where to start testing look at SMS :)
HAPPY 2010 for everyone
