Exporting to SVG mirrors the rotation lists of every vertex

[arnegoeteyn]

Exporting a cage-generated image to SVG results into a SVG file where the rotation around every vertex is mirrored.
The 2D-viewer in CaGe shows the correct image.

Below I added a the writegraph2d file that was used for generating this image trough CaGe.

This is not necessarily an issue. The direction of the cyclic order is not determined by the file format. So either choice is actually valid. I do agree that it might be better that the viewer and the export use the same convention. I should have a closer look, but I think the reason is that both actually use the same coordinates, but they use a different coordinate system: origin in the bottom left corner vs origin in the top left corner.

A work-around for now is to simple open the image in any program that can manipulate SVG (like e.g. Inkscape) and just vertically mirror the image.
