   Priority:  medium       |   Milestone:  2.1  
  Component:  General      |     Version:  2.0.0

---------------------------+------------------------------------------------
 When stylizing geometries, null check was purposely ommited because it was
 believed to incur additional overhead to check for null before retrieving
 the geometry. Geometry value generally should not be null, but there is no
 guarantee of this. If a null does occur, it is handled by catching the
 exception and ignoring it which actually slows down the reading of the
 data.
