Add a combiner test for the case where the final combiner not used #56

Open abaire opened 2 years ago

If all of the final combiner values are set to 0, the R0 output of the last combiner stage should be used as the fragment color. Add a test to verify this behavior (set all registers to distinct colors and validate that only R0 contributes to the output)
