Postscript filling patterns
GMT for now can use only 2-color bitmap patterns for area filling. This is artifical restriction because PostScript allow using any code as filling pattern with any number of colors. I propose to add the ability to use custom PostScript patterns, as has been done for custom symbols. I think this is rather simple task, because all you need is to replace /PaintProc entry in the pattern dictionary. I attach the example of psxy output there GMT-generated /PaintProc replaced on my variant.

It is worth looking into but not a high priority yet. Some years ago I did test out a new PostScript pattern scheme by following the Abobe PS Red book and it worked fine. But Adobe Illustrator was unable to parse their own damned PostScript examples [improving freeform PS import in AI is an extremely low priority for Adobe]. And then we get the blame for "Bad" GMT PostScript. So I am a bit leery of jumping in the second time. Once bitten, twice pissed off.
