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

-------------------------+--------------------------------------------------
 Right now, functions in liblwgeom duplicate a lot of code handling empty
 inputs. When people add new types, the lack of support across all
 functions can cause unpredicable failures. The handling of higher
 dimensions is not consistent or declared.

 Idea form code sprint:
 - MACRO magic to test for
   o TYPE support
   o SRID support
   o dimensionality support
   o check EMPTY
   in liblwgeom functions and return useful error
