This patch makes a distinction between passes accessed through nodes
like the Render Layers node, and inputs accessed through nodes like the
Group Input node. Previously, the Group Input node returned the passes
of the active scene and view layer accordingly to the name, while now,
it only returns the Image (Combined) pass and the result will be zeros.
