Bug Description

Gerber allows optional primitive arguments (e.g. for circles an optional rotation parameter can be given). While the appropriate behaviour to handle them is is properly documented in the code, it is not implemented.

This results in the 'sample_macro.gbr' of the Ucamco test suite (
 getting parsed incorrectly (see attached images).

The fix is simple. I have attached a patch.

Thank you for fixing this so quickly!

Sorry my patch was a bit hacky. After checking back with the spec indeed only circles can have an optional rotation argument, my bad.

Have a nice day :)
