- Add support for `wx.adv.OwnerDrawnComboBox` and `wx.ComboCtrl` in the documentation building process. Add the appropriate samples as well (and wonder why the sample in `wx.ComboCtrl` doesn't get properly highlighted...). git-svn-id: https://svn.wxwidgets.org/svn/wx/wxPython/Phoenix/trunk@71669 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
