Apply arbitrary coordinate transformation to geometry.<p>
This method will transform the coordinates of a geometry from their current spatial reference system to a new target spatial reference system. Normally this means reprojecting the vectors, but it could include datum shifts, and changes of units.<p>
Note that this method does not require that the geometry already have a spatial reference system. It will be assumed that they can be treated as having the source spatial reference system of the <a class="el" href="classOGRCoordinateTransformation.html">OGRCoordinateTransformation</a> object, and the actual SRS of the geometry will be ignored. On successful completion the output <a class="el" href="classOGRSpatialReference.html">OGRSpatialReference</a> of the <a class="el" href="classOGRCoordinateTransformation.html">OGRCoordinateTransformation</a> will be assigned to the geometry.<p>
