/**
    @class wxAuiDockArt

    wxAuiDockArt is part of the wxAUI class framework.
    See also @ref overview_aui.

    wxAuiDockArt is the art provider: provides all drawing functionality to the
    wxAui dock manager. This allows the dock manager to have a plugable look-and-feel.

    By default, a wxAuiManager uses an instance of this class called
    wxAuiDefaultDockArt which provides bitmap art and a colour scheme that is
    adapted to the major platforms' look. You can either derive from that class
    to alter its behaviour or write a completely new dock art class.
    Call wxAuiManager::SetArtProvider to force wxAUI to use your new dock art provider.
