Speaking from personal experience, ImageMagick does quite a poor job
of rasterising SVG images.

rsvg (from librsvg), which is quite straightforward to compile,
although there might be packages for Solaris.

Bear in mind this is talking about using ImageMagick for thumbnailing
bitmap formats, rather than SVG, and also bear in mind that it's on a
page of stuff for Windows. I've never experienced trouble with it, but
it's possible some contributor has had problems using ImageMagick
under Windows in the past.
