I agree with you, we need this...

Another question, do we need a state plugin?
blur, switcher, ... now use "window matching"  to enable/disable effect. With 
your proposition, we should be able to specify blur type.

So, with window matching, bs plugin should set brightness/saturation, place 
plugin should set window position/stacking, decoration plugin should set 
decorations, ...

So my question is: Should we have a state plugin or should we have a per 
plugin window matching? I know it will increase plugin size, but i think it 
should make compiz configuration much more consistent (instead of having some 
matching in plugins and some matching in state)

Another thing, for now, opacity increase/decrease is in core, i think it 
should go in bs plugin (rename it bso plugin).
