wxdcclipper

wxdcclipper is a small helper class for setting a clipping region on a wxdc and unsetting it automatically. an object of wxdcclipper class is typically created on the stack so that it is automatically destroyed when the object goes out of scope. a typical usage example:

    void myfunction(wxdc& dc)
    {
        wxdcclipper clip(rect);
        ... drawing functions here are affected by clipping rect ...
    }

    void otherfunction()
    {
        wxdc dc;
        myfunction(dc);
        ... drawing functions here are not affected by clipping rect ...
    }
