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

[Jeffrey H]

When I read the first mail, I interpreted it as a radial dial, much like
After Effects does its orientation controls (this one:
https://blogs.adobe.com/bobddv/files/bobddv/images/fractalnoise_2.jpg);
this would be easier to plug into other nodes for directional information
as it could be a node of its own and give visual feedback of what angle is
being output. I'd have to draw up my input for the manipulator handles when
I get home, though (I also need to try out the patch from Lukas to see
what's on the table).
