I'd be happy to contribute to such an effort and have more experience than most with regard to graph-building in VB6. In particular, I am very interested in a robust SampleGrabber. Geraint Davies capstill.dll is fine up to a point, but will only accept 24bit RGB inputs and some upstream filters are not always willing to provide this! An overlay filter would be great too as would (getting greedy now!) a filter that one could use to adjust RGB, HSL on-the-fly.
