[Bf-committers] New compositor issues

[Antony Riakiotakis]

As expected, merge with trunk is the second best way to test (release
is first :) ).

Testing here as well. I see a few weird things such as possibly
clamping issues with RGB curves or strange things with depth of field
when "fix gamma" is checked. The bug trucker is our friend!

Other than that great work Jeroen, and thanks a lot for this!
