LAYOUT improvements

Rhino 6 is fantastic, but seriously lacking in its layout capabilities.
Laying out technical drawings is fundemental for communicating clearly.

A couple of things I need to be able to do in Layout.

  1. Print PNG’s with transparent background (currently the PNG prints black background)
  2. Trim lines on details in layout without it effecting the real model.
  3. Create a curved break Inbetween details

If Rhino can currently do these things in Layout PLEASE let me know.
