#2428: Add a "perQuadrant" parameter to ST_LineToCurve

     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.2.0
Component:  postgis      |     Version:  trunk

-------------------------+--------------------------------------------------
 ST_CurveToLine has a parameter to request a number of edges per circle
 quadrant. For symmetricity the same parameter should be accepted by
 ST_LineToCurve to control the minimum number of edges per quadrant
 required to define a curve. See also #2407

 NOTE: this change affects liblwgeom interface which may be changed
 (cleaner) or augmented (only worth to retain backward compatibility).
 The relevant liblwgeom interface is:

 {{{
  lwgeom_desegmentize(LWGEOM *);
  lwgeom_segmentize(LWGEOM *, uint32_t);
 }}}

 My suggestion is to change lwgeom_desegmentize to also take an uint32_t
 (backward incompatible change).

 Wouldn't 2.1 be a perfect moment for this ? :)
