36/** This structure specifies an arbitrary elliptical arc.<p>
37
38    This structure contains all parameters necessary to specify
39    arbitrary elliptical arcs. The parameters are modelled closely
40    after the <a href="www.w3c.org">SVG</a> specification.<p>
41
42    As with the parameters below, there are mostly four different
43    ellipses arcs (two different ellipses, on which four different
44    arcs connect start and end point) which satisfy the given set of
45    constrains. Thus, there are two flags indicating which one of those
46    ellipses should be taken.<p>
