Store geometry per IfcShapeRepresentation #501
Is there any particular file/element you have in mind where this is supposed to work?
Benefit: Probably even more abilities to re-use geometry 
Less nice: More fragmented draw operations for separate items reduce performance
 keep in mind that due to openings and placements (and sliced material layers if enabled), some checks are needed to determine what things can be re-used. Layer associations, openings, ... are all determined on the product level.
