controlling ClutterEffects order

[Max Kolesin <mkolesin gmail com>]

Hi,

I'm currently facing a problem that it's sometimes necessary to control multiple ClutterEffects pre/post-paint order. Wasn't there any interest in adding such api before?

I just can't figure out which would be the best way to do it. Obviously, it has to end up in adding some kind of "priority" value and a sort function either to ClutterEffect or ClutterActorMeta. I could come up with a patch for it, since i don't want to divert my project from clutter main repo. Just need some guideline on how in fact it should be done, in order to correspond to current ClutterEffect API.

Regards,
