In VapourSynth the red, green, and blue pixels are in individual arrays (R0 R1 R2..., G0 G1 G2 ..., B0 B1 B2 ...), so the equivalent VapourSynth code will be a bit simpler.

I got debugging working, YAY! (built the original Vdub gradation curves filter, to see how the data is supposed to look with the original vdub filter) I built the solution, set debugger to launch virtualdub, and then once virtualdub loaded I went to video add filter, and loaded the debug copy of the filter that I just built.
Now I just need to be able to understand the data, alot of these fields can be expanded, for some reason I expected it to look a lot simpler, showing an R G and B value somewhere between 0 and 255...
