[Bf-committers] Autorefresh Renderlayers

[Daniel Salazar - 3Developer.com]

In the hopes of bringing the compositor closer to an integrated 3D
environment and tackle the interactivity problem I want to propose
this feature.
RenderLayer Auto Refresh (optional per render layer input node):

Now I know it sounds scary but I believe we can leave to to the user
the task of setting it up in a way that is fast to render (use a
simplified scene/renderlayer with heavy render features turned off
etc)
The above diagram is of course just one example of usage, but I don't
think this will limit to 2D masking. It could be tracking a 3D mask or
a complex object (modifiers etc) with ob ID or who knows.

hope to hear comments from other compo people
cheers
