/*
getPathSegAtLength() returns the index into pathSegList which is distance units along the path.
Parameters
in float distance The distance along the path, relative to the start of the path, as a distance in the current user coordinate system.
Return value
unsigned long The index of the path segment, where the first path segment is number 0.
See specification for detail: http://www.w3.org/TR/SVG/paths.html#DistanceAlongAPath
