Extracts of the portions of protovis that we actually use in CODAP, enabling us to get rid of the rest of protovis.
We have extracted the portions of protovis that we need having to do with formatting, color, and svgScene. So we can delete the file as a whole.
Replace calls to protovis with calls to the extracted portions of CODAP. E.g. pv.color gets replaced with DG.color.

Also, sc_requires that referred to protovis now need to refer to the relevant utility extracted from protovis.
