Returns the bounding rectangle of this section. A normalised coordinate is needed for tapering sections - use 0 for non-tapering sections. For multi-varying sections that are set to 'follow path', a line ID must also be passed in, so that the path coordinates (chainage) can be calculated. For all other sections, the line ID is optional. For any kind section, if a line ID is passed in, the eccentricity of the section at the given location will also be calculated and returned. If the line is given as 'nothing', the eccentricity cannot be calculated, and will be returned as 0

| yMax | double | top coord relative to centroid |
| yMin | double | bottom coord relative to centroid |
| zMin | double | left coord relative to centroid |
| zMax | double | right coord relative to centroid |
| ey | double | eccentricity of section |
| ez | double | eccentricity of section |
| Return value | none |
