Fixed in CVS. It was not translating the typedef.

******* NOTE
I changed the $typedef semantics to match that of C/C++
%typedef wxPoint2DDouble a2dPoint2D

Should work? See wxPoint2DDouble operators.

There is no support for 2 params to the operators, I can add this.

This would be hard to implement since we'd have to return m_matrix[3]
as an array wrapped in a new userdata type that would allow you to get
to the second [2] dimension. I would provide a safe member function,
with bounds checks so you don't get a segfault with no error message
if you try to access a value out of bounds.

Treat this as a function, the binder doesn't know the difference.
%function double Round(double x)
