Swig and contructor overloading...

[Tamas Szekeres]

Steve,

This change breaks the compatibility with the existing interface that
causes compilation error with c# (the samples like shpdump uses the
original constructor).

However the compatibility could be maintained by keeping the original
constructor in addition to the new.

SWIG 1.3.27 can handle multiple constructors accordingly (C#)

Does anyone know if this is still true in the newest version of Swig? I
know they did some work to standardize things across all languages
recently. If this will be problem, then we have to address it. We could
just tackle it with documentation since those bindings are not yet as
popular. We could move creation from WKT into a seperate method. Or?
