Notice that the 8 lower bits overlap with wxCENTRE and the button selection
bits (wxYES, wxOK wxNO, wxCANCEL, wxAPPLY, wxCLOSE and wxNO_DEFAULT) which
can be combined with the dialog style for several standard dialogs and
hence shouldn't overlap with any styles which can be used for the dialogs.
Additionally, wxCENTRE can be used with frames also.
