Comment 10 for bug 707290

Thank you for the detailed descriptions of the problems. I will try to find time soon to fix them.

What would be preferred behaviour in the case of incompatible parameters given by the user (e.g. a center hole larger than the gear itself)?
- Render the faulty gear (including too large 'center' hole) anyway?
- Render the gear without center hole?
- Render the gear with an as-large-as-possible center hole?
- Render an error message as text?
- Render nothing and use inkex.errormsg() for feedback? (as far as I understood, this feedback is hard to find for end users...)
- Anything else?
