To be clear, my proposal is unrelated to the compositor. But I think
you know that and are suggesting that a smarter view-draw system could
be used to improve previewing of operations in the compositor. It did
occur to me that the node editor could be used generate view port
drawing scripts. However, I am imagining a lower level system, more
suitable for programmers than artists.
If you would elaborate on some of the "dozens of actions" this might
enable I think I'd be more clear on what you mean.
I'll change the name my proposal to something like "Blender View Port
Effects (FX)" so there is no confusion. I do not want to second guess
every time somebody says "compositor" :-)
