I believe we need to do some metaclass programming to solve this one. In
the __init__ of dForm, we swap out __bases__ depending on whether the form
is to be modal, and whether the form is to be SDI or MDI.
I didn't realize it at the time, but this changes the {{{__bases__}}} of
running forms as well, but at some point Python resolves the
{{{__bases__}}} again correctly. So, at this time I'm not sure how big a
problem this is, but I've noticed it in a specific case: after I show and
hide a modal form, I can see that my main modeless form's {{{__mro__}}}
contains wx.Dialog instead of wx.Frame.
