The typename wxPoint2DDouble should be known if you have this line in
your rules since the file wxcore_datatypes.lua defines them.
datatype_cache_input_fileTable = {
wxlua_dir.."bindings/wxwidgets/wxcore_datatypes.lua" }
The typedefs have not been thoroughly tested as they're not used too
much in the bindings. You're saying that if you have something like
this in your interface files you get a crash. For both uses of the
typedef or only for the return value... ? This should be fixable if I
can get a simple example of what makes the binder crash.
%typedef a2dPoint2D wxPoint2DDouble
%function a2dPoint2D GetPoint()
%function void SetPoint(const a2dPoint2D& pt)

There is no support for templates, therefore you have to define each
templated class. However, if you can, wrap the base class and then for
each templated class only override the functions whose input or output
data types are different.
