Hi there!
Any thoughts on implementing SVG gradients in MetaPost?

See attached a comparison of the PDF generated using ConTeXt and the
PNG file generated by exporting from Inkscape.
these gradients definitions get crazier by the day ... does inkscape
output a bitmap or vector pdf
given what we do with context i'm not sure we should support everything
that pops up (mapping all onto mp and then pdf ...)
