Snaps a LinearRing based on a set of LineString.
| rtree | The R-tree contains the candidates envelopes as reference to snap. |
| referenceSegments | A vector of LineString that is used as reference to snap. |
| setIndexesIgnored | A set of indexes of candidates that had must be ignored in the processing. This set is used for optimization purposes |
| wasChanged | This is an output value to inform if the geometry has been changed or not during the prepare |
| linearRingToSnap | A LinearRing that will be snapped. |

It encodes the line to WKB.
This is a special helper function that writes just the number of points in the line and its coordinates. No byte order or geometry type is written to the buffer.
| l | The line to be serialized to a wkb. |
| nPts | The number of points in the line to be encoded in the WKB.. |
| wkb | The buffer to serialize the line number of points and coordinates. |
| byteOrder | The byte order used to encode the wkb. |
