[def __this_function__ comparable_distance]

[heading_conformance_no_ogc __this_function__]

[heading Behaviour]
It depends on the coordinate system of the geometry's point type if there is
a strategy available which can determine (more efficient than the standard
strategy) a measure of comparable distance.

[include reference/status/distance_status.qbk]

[heading Complexity]
For point to geometry: linear

For multi-point to ring/polygon/multi-polygon: currently quadratic

For all other geometry combinations: linearithmic
