getLabelPoint() does not work for polyline and point layers.

Using the feature method getLabelPoint(), this works for polygon layers but not for polyline layers, it always return nulls. While looking at the source code, in mapscript_i.c, we see the check being done for if it’s a shape of type polygon; otherwise a null value is returned. pointObj *shapeObj_getLabelPoint(shapeObj *self) {

pointObj *point = (pointObj *)calloc(1, sizeof(pointObj)); if (point == NULL) {

msSetError(MS_MEMERR, "Failed to allocate memory for point", "getLabelPoint()"); return NULL;

}

if(self->type == MS_SHAPE_POLYGON && msPolygonLabelPoint(self, point, -1) == MS_SUCCESS)

return point;

free(point); return NULL;

}

Why polyline, or point also, does not return a point object. Since there is a msPolylineLabelPoint(…) in mapprimitive.c, shouldn’t polyline object be also supported when trying to get the point of the label? Shouldn’t the point object should be also supported?
