Add some UI to shader nodes in the NodeEditor to represent the available plugs

[bentoogood]

Will help users be aware of available plugs and could offer a mechanism for creating nodes already connected to those plugs.

[bentoogood]

And when I say plugs I mean plugs that have a nodule and therefore are 'plug-able'

if you know what I mean....

I seem to remember we agreed that this would be done in Graffer in the short term? Can I move it out of the milestone?

[bentoogood]

Hmm - looking at the graffer tickets, we agreed to do it gaffer side :)

But it is low priority.
Something we can come back to later.

[johnhaddon]

I thought in the last skyping we said that since we already had the input creation logic in Graffer (for the right click menu), that we would do it there for now?

[bentoogood]

Let's confirm on thursday. But either way, it's one to ignore for now.

[johnhaddon]

We forgot to discuss this one in the conference call - any update from your side?

[bentoogood]

No update - we can make sure we get David in on next conversation.
Any pressing need, or are you just checking over all tickets?

[johnhaddon]

No pressing need - I was just giving the tickets a once over and realised we forgot to clarify on this one.

[bentoogood]

This just came up with Yuta, so bumping priority

Agreed plan:

• First pass:
  • Add row in NodeEditor to represent eacg available pluggable plug
  • Add gui element to row that shows the name of the input plug ( or 'none' if there is no connection )
  • Add gui element (button) to row that if clicked will select the input node in and make it active in the NodeEditor
  • Should it be active in any Viewers too? Just do what ever a double click does?
• Second pass (on backburner for now):
  • Add gui element to row that if clicked presents list of nodes available for connection (filtered by plug type)
  • If item in list is clicked, create that node and connect the output to the current node.
