* Add new utility to calculate packed dl end and vertex count Requires changing a bunch of actual references to packed dl lists with raw numbers. Which feels extremely bad but it doesn't match otherwise. Signed-off-by: Taggerung <tyler.taggerung@email.com> * Hard code array lenghts in appropriate headers Use macros to generate the vertex counts and packed dl end points Heavily dependent on the array lengths being accurate. If they aren't stuff will break. Signed-off-by: Taggerung <tyler.taggerung@email.com>
