[Bf-committers] Proposal: 2D handler for Compositor

[Sam Vila]

I think a radial dial wont be as good as having a handler node or similar,
this way you can have a node adjusting many other elements into other
nodes. For example you can create a node handler that has an absolute
position and many other nodes are reading this position to add their
effects.

After effects is doing this in a very good way, you can have a null object
that affects layers, transformations, effects and so on so instead of
tweaking each individual effect you have a master object that tells the
position to be used in several effects at once.
