clutter: Use paint context to get paint target framebuffer

Browse source 
Instead of using the intermediate stage state "active framebuffer" to
find the framebuffer a paint eventually targets, use the "base
framebuffer" of the paint context, as this more correctly corresponds to
the end point of a paint. It also means we can then later remove this
intermediate state from the stage.
