#391: Unify Concept of "Edge"
---------------------+------------------------------------------------------
 Reporter:  pramsey  |       Owner:  pramsey       
     Type:  defect   |      Status:  new           
 Priority:  medium   |   Milestone:  PostGIS Future
Component:  postgis  |     Version:  trunk         
 Keywords:  curve    |  
---------------------+------------------------------------------------------
 Right now, we have curves and lines, the "only" difference between them
 edge interpolation. A good deal of the mechanics of things like
 calculating lengths and perimeters is identical for curved and linear
 things. To the extent that these mechanisms can be unified, things like
 implementing LRS code on top of generic geometry becomes easier.

 Proposal, a single "edge" concept suitable for passing to things like
 distance calculations, interpolation calculations, and so on, such that
 implementations of LRS, length, intersection, etc, calculations can be
 unified.
