#4 convert "fails" with svg/svgz files (broken images)

Hi uellue,

the converted svg/svgz images of ImageMagick (convert)
are broken (cropped images, no color gradients or
transparent parts, ...).

PyGallue uses rsvg-convert from librsvg2-bin for the
preview images. This looks much better!

Maybe we could use it (if installed) instead of
ImageMagick for svg/svgz images?

That's a good idea! I just updated the roadmap...

To hack the converting process in a way "if SVG then (cool
SVG converter) elseif otherFormat (other cool converter)
elseif ... else (default converter)" is not such a good
idea. We could instead use rsvg-convert, dcraw and other
converters to import images and convert them to a compatible
intermediate format, for example TIFF (or PNG, but that's
inefficient because of compression). This intermediate
format could be converted, e.g. resized and rotated. If we
want to create an instance with a format that isn't
supported by convert, we could again export to a compatible
format and use another filter to create the instance
finally. In the end, this would be a complete redesign of
the converting process (and a big improvement in regard of
flexibility). We could, for example, add a descriptor for
each filter in a form "accepts these fomats, can perform
these operations, can output these formats". For a given job
(input format, filter operations, output format) the
converting process could search a combination of filters
that can do the job with a minimum of effort.

Thank you very much for the inspiration! . I don't know a
quick workaround at the moment, so we'll have to wait until
I implement the above algorithm.
