glMultiDrawElements

• Figure out the deal with all of the clipping which is happening.
  • May be due to lack of effect shader programs or some issue with texture binding.
  • Review node lookup in the bsp traversal to ensure faces are being added to their surfs properly. For example, when a new surface is created and moved to the vector, does the std::move properly perform the operation?

    Iterative

• Minimize the amount of objects being looked up for a given face which happen per frame. For example, if a shader can be looked up once and passed to multiple functions for further evaluation, that's the way to go. ( some improvements could still be made here, but for the most part this is taken care of)

  Inline

• Once a function grows past 6-8 lines, remove the inline.
