/*C+ CSDrawLine
*
*    DESCRIPTION:
*
*    The CSDrawLine component provides the ability to draw a line
*    on a CanvasShellDisplay.
*
*    INHERITED CLASSES:
*
*    CSComponent - A CSDrawLine object is a CSComponent.
*
*    PUBLIC MEMBER FUNCTIONS:
*
*    void setArrowAngle0 (int new_angle)
*    void setArrowAngle1 (int new_angle) 
*		- Set the angle of the tip arrow, new_angle is 
*		  measured in 64ths of a degree for end points 0 and 1.
*
*    void setArrowInsetLength0 (int length) 
*    void setArrowInsetLength1 (int length) 
*		- Set the length of the line that makes up the arrow
*		  for end points 0 and 1.
*
*    void setArrowHeadLength0 (int length) 
*    void setArrowHeadLength1 (int length) 
*		- Set the length of the arrowhead along the cutting edge.
*		  for end points 0 and 1.
*
*    void setArrowStyle0 (Arrow_style style)
*    void setArrowStyle1 (Arrow_style style)
*         - The style of the arrowhead for end points 0 and 1:
*
*        	ARROW_FILLED
*        	ARROW_HOLLOW
*       	ARROW_SIMPLE
*       	ARROW_NONE
*
*    void setX0 (int x) - Set the X coordinate of endpoint 0.
*
*    void setX1 (int x) - Set the X coordinate of endpoint 1.
*
*    void setY0 (int y) - Set the Y coordinate of endpoint 0.
*
*    void setY1 (int y) - Set the Y coordinate of endpoint 1.
*
*    int getX0 () - Get the X coordinate of endpoint 0.
*
*    int getX1 () - Get the X coordinate of endpoint 1.
*
*    int getY0 () - Get the Y coordinate of endpoint 0.
*
*    int getY1 () - Get the Y coordinate of endpoint 1.
*
*    PROTECTED MEMBER FUNCTIONS:
*
*    virtual void createObject (UIObject *) - Creates the XView
*    DrawLine encapsulated by this object.
*
*    PRIVATE MEMBER FUNCTIONS:
*
*    void setCSDrawLineDefaults () - Initializes data members.
