[NTG-context] file with too many radial shadings

Hi there, some months ago I discovered that one file generated with LuaTeX + ConTeXt was too slow using mupdf (a PDF viewer). So I filed a bug (http://bugs.ghostscript.com/show_bug.cgi?id=692500) and one of the developers replied that the file contained too many radial shadings, most of which were identical. I wonder whether this bug still affects to current releases from LuaTeX and ConTeXt. Just in case it might help, Pablo -- http://www.oudeis.tk
