\section{\class{wxGraphicsPath}}\label{wxgraphicspath}

A wxGraphicsPath is a native representation of an geometric path. The contents are specific an private to the respective renderer. Instances are ref counted and can 
therefore be assigned as usual. The only way to get a valid instance is via a CreatePath call on the graphics context or the renderer instance.

GetNativePath is newly allocated each time).
