    Low word style bits is class-specific meaning that the same bit can have
    different meanings for different controls (e.g. 0x10 is wxCB_READONLY
    meaning that the control can't be modified for wxComboBox but wxLB_SORT
    meaning that the control should be kept sorted for wxListBox, while
    wxLB_SORT has a different value -- and this is just fine).
