* Tweak six a little, adding its license text since we'll only be distributing the module, fix the name of the dummy moves module, and add a PY33 constant since the change in memoryview affects our code. * Update all modules already using the old wx2to3 * Tweak lots of unit tests and other modules to work with Python 3.3 (still a few more that will need some work.) * Try to deal with memoryview changes in Py3.3, without much luck... git-svn-id: https://svn.wxwidgets.org/svn/wx/wxPython/Phoenix/trunk@73195 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
