Realtime Compositor: Add stub unsupported nodes

This patch adds a stub implementation for all unsupported nodes. The
inputs are passed through to the outputs where it make sense, while
other outputs will be allocated a single zero value.

This seems to be preferred by users as opposed to stopping execution and
displaying an error message.
