[wxVTK] Little bug when using not wxGTK

[<rei...@gm...>]

Hello Mathieu,

In the 1.0 release of wxVTK seems to be a little bug. In the following
method I had to add the preprocessor directives for MSW. The reason is
that for MSW the wxVTKRenderWindowInteractor inherits from wxWindow
instead of wxGLCanvas...

Regards,
	Reinhold


void wxVTKRenderWindowInteractor::Enable()
{
  // if already enabled then done
  if (Enabled)
    return;

  // that's it
  Enabled = 1;
#ifdef __WXGTK__
  this->SetCurrent();
#endif
  Modified();
}
