> I have a PDF file (for which I do not yet have release permission) that uses the "sh" operator, equivalent to PostScript's shfill (per PDF spec 1.7 page 987).
> Adobe provides implementation guidance in a 78-page document at http://www.adobe.com/devnet/postscript/pdfs/TN5600.SmoothShading.pdf#17
> I will be trying to add this functionality this week, but if anyone has hints, suggestions, etc. they are most certainly welcome!
