#2756: ST_Extrude of M geometries looses M
--------------------+-------------------------------------------------------
 Reporter:  robe    |       Owner:  colivier     
     Type:  defect  |      Status:  new          
 Priority:  low     |   Milestone:  PostGIS 2.2.0
Component:  sfcgal  |     Version:  2.1.x        
 Keywords:          |  
--------------------+-------------------------------------------------------
 I'm not sure if this is a bug or anything that can be done about it.  At
 very least we should probably document the behavior that M coordinates are
 lost during extrude process.


 {{{
 SELECT ST_AsText(ST_Extrude('LINESTRING M (-10 50 1,50 -10 1)'::geometry,
 20.1,20.1,20.1) );
 }}}


 This is one of the garden monkey tests which yields:

 {{{
 POLYHEDRALSURFACE Z (((-10 50 0,50 -10 0,70.1 10.1 20.1,10.1 70.1 20.1,-10
 50 0)))
 }}}
