#3974: ST_AsX3D revise to use stringbuffer
-------------------------+---------------------------
 Reporter:  robe         |      Owner:  pramsey
     Type:  enhancement  |     Status:  new
 Priority:  blocker      |  Milestone:  PostGIS 2.5.0
Component:  postgis      |    Version:  trunk
 Keywords:               |
-------------------------+---------------------------
 Right now the lwout_x3d.c file is a mangled mess of sprintfs.  By moving
 much of this logic to stringbuffer, the code will be significantly shorter
 and probably better able to generate large X3D documents which as I
 recall, someone complained about a while ago.

 Once I have this in place I'll move on to the other tasks of supporting
 Curves, #1416 and #3705
