/*C+ CSDrawArea
*
*    DESCRIPTION:
*
*    The CSDrawArea component provides the ability to draw on
*    a CanvasShellDisplay.
*
*    INHERITED CLASSES:
*
*    CSComponent - A CSDrawArea object is a CSComponent.
*
*    PUBLIC MEMBER FUNCTIONS:
*
*    void setLeftX (double)
*    void setRightX (double)
*    void setUpperY (double)
*    void setLowerY (double) - Sets the dimensions of the CSDrawArea.
*
*    double getLeftX ()
*    double getRightX ()
*    double getUpperY ()
*    double getLowerY () - Gets the dimensions of the CSDrawArea.
*
*    PROTECTED MEMBER FUNCTIONS:
*
*    virtual void createObject (UIObject *) - Creates the XView
*    DrawArea encapsulated by this object.
*
*    void setCSDrawAreaAttributes (UIObject *) - Sets XView attributes.
*
*    PRIVATE MEMBER FUNCTIONS:
*
*    void setCSDrawAreaDefaults () - Initializes data members.
