// -- wxAuiDefaultDockArt class implementation --

// wxAuiDefaultDockArt is an art provider class which does all of the drawing for
// wxAuiManager.  This allows the library caller to customize the dock art
// (probably by deriving from this class), or to completely replace all drawing
// with custom dock art (probably by writing a new stand-alone class derived
// from the wxAuiDockArt base class). The active dock art class can be set via
// wxAuiManager::SetDockArt()
