[wxMac] Updates for latest CVS

Hi folks,

I'm building wxPython with CVS HEAD on Mac as that's a good way to test the new changes (now that the C++ samples are starting to stabilize), and I thought I'd note any areas where I ran into troubles. However, when trying to run SWIG I'm getting a "Syntax error" on the following line:

%fragment("SWIG_AsUnsignedLong","header", fragment="SWIG_AsLong") %{

I'm trying with SWIG 1.3.21, which as far as I can tell seems to have all of the patches in the wxPython/SWIG folder already applied. Any suggestions? =)

(BTW, I'm rebuilding because I'm getting errors that wxWINDOW_VARIANT_* are not declared in global scope.)

Also, I found one place in the helper code that needs updated to accomodate the latest changes:

- wxPython/src/mac/helpers.cpp: MacGetRootWindow (line 1813) needs to be changed to MacGetTopLevelWindowRef().

Thanks,

Kevin
