Runtime effects: Support input color as a parameter to main()

For now, just bolt this onto the existing runtime effects. The next step
is to add dedicated modes to the compiler for shader vs. color filter.
Once we get there, we will be much more strict about main signature in
each mode (and start adding other per-mode error checking).
