Correct a bug in DistortedBuffer: we only mark it for creation when we actually have all the data ready, otherwise it can happen that create(0 is called before setData() !
Improve locking in DistortedObject.DistortedMaster: slaves can be NULL !
Small things.
Port all the 'non-controversial' changes from order-independent-transparency branch.
SSBO: now we have a more-or-less correct running average of the count of transparent fragments over the last few frames.
Small API simplification.
Progress with support for Effect classes.
