-- aCurve with respect to the maximal chordial deviation defined
-- by the drawer aDrawer.
-- The aspect is defined by LineAspect in aDrawer.
-- If drawCurve equals Standard_False the curve will not be displayed,

---Purpose: adds to the presentation aPresentation the drawing of the curve
-- aCurve with respect to the maximal chordial deviation defined
-- by the drawer aDrawer.
-- The aspect is defined by LineAspect in aDrawer.
-- The drawing will be limited between the points of parameter U1 and U2.

-- Points give a sequence of curve points.
-- If drawCurve equals Standard_False the curve will not be displayed,
