That's good. That just tells _WRAP_CTOR() to look at gdl_dock_new_from()
to see what C parameter types it takes, so it can know how to convert the
C++ parameters to the C parameters (by looking at the .m4 conversion
files.). It then uses g_object_new() in the generated .cc file.

You just need to make sure that you don't hard-code a _new function into
the .ccg file. Where you need to hand-write a constructor, look at the
gtkmm .ccg files - there's a macro (_CONSTRUCT, or something like that)
that helps.
