original .svg file

cairo script is a wonderful debugging facility. It can also serve to store
cairo drawings. I am using it as a workaround to the lack of .svg decoding
support in cairo. The idea is:

- render the .svg with librsvg while capturing the output into a .cs file,
- replay the .cs file with cairo-interpreter.

By and large the approach works, if only the capture/replay process worked
correctly. I am providing 3 attachments. The first is a .png generated by
librsvg and a corresponding .cs, captured by cairo and a .png, generated by
replaying the .cs. The .cs generates a blue "halo", where a shadow should be.
