Summary: wxPdfDoc - Path filling rules

Initial Comment:
The PDF format allows the specification of the rule for determining which parts of a polygon to fill. This is used when the path intersects itself or has one subpath that encloses another. 

Currently only the non-zero winding rule is supported, and is fine for most cases. The other fill method is the 'even-odd' rule (section 4.4.2 of the Adobe PDF reference sixth edition).

The attached patch is a quick hack to support the even-odd rule for the shape object. It should probably be  made an option in pdfproperties.h under style options and all the cases where these options used in the code updated.

This is probably a low priority feature, the standard rule will be good for nearly every case.



Thanks

Ben
