[Bf-committers] openmp

[rafa]

Hi Jeroen,
  I understand that the new compositor has big improvements that 
wouldn't be possible without this new redesign, but I would like to know 
the tests that you did to see if there is some room to improve the 
current compositor.
  I don't know if there is time to include a possible improvement in the 
current trunk or if it would be posponed and the new desing will arrive 
by then.

  Anyway, I would like to give a hand trying to improve the current or 
with some work in the new one.


Greetings
Rafael Rios
