Comment 3 for bug 171186

> It is a perfectly valid request,

No one ever said it wasn't.

Inkscape cannot possibly implement all valid requests there
just are not enough developers and users must understand
that things will only happen if there is a developer
interested in doing the work.

raising money to sponsor a developer might help make this
happen.

the lack of any documentation also makes it even harder to
implement a file format but if you can find documentation or
help to reverse engineer the format it would certainly help.
