52 // wxAuiManager. This allows the library caller to customize the dock art
53 // (probably by deriving from this class), or to completely replace all drawing
54 // with custom dock art (probably by writing a new stand-alone class derived
55 // from the wxAuiDockArt base class). The active dock art class can be set via
