Added a set of 2.4 compatibility classes for the wxDC classes that

Browse Source 
replaces the normal Draw methods with those that have 2.4 compatible
parameter lists.  These classes are used by default only when
importing from wxPython.wx (the "old" namespace.)

these changes, but it should be easy to fix the code. You can either
change the name of the *Type B* method called to the names shown

Now before you start yelling and screaming at me for breaking all your
code, take note that I said above "...using the new wx namespace..."
That's because if you are still importing from wxPython.wx then there
are some classes defined there with Draw and etc. methods that have
2.4 compatible signatures. However if/when the old wxPython.wx
namespace is removed then these classes will be removed too so you
should plam on migrating to the new namespace and new DC Draw methods
before that time.
