#3186: mixed dimmentionality in ST_AsTWKB gives strange results

 Priority:  medium   |  Milestone:  PostGIS 2.2.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 ST_AsTWKB version that takes input from array of geometries have no check
 for mixed dimensionality.

 In theory when returning a collection type (7) it would be possible to
 handle mixed dimensionality. But since all geoemtries is transportet
 internally as geometry collection it doesn't work.

 And the very first byte in the twkb will then be inconsistent with the
 subgeoemtries
