Add

   -debug coder

prior to out.png to see what settings are used for the PNG.

Note that ImageMagick may be using librsvg or the rsvg utility to 
render the SVG and this will lead to different results than if the 
built-in SVG renderer is used.  The built-in SVG renderer is not very 
good according to today's standards.

It should be fairly easy to add use of rsvg via an entry 
in delegates.mgk but the existing SVG coder would need to be disabled 
somehow.
