Pre-calculate the frustum clip flags and cull backward facing bmodel faces. This takes advantage of the surface bbox info and gives a small speedup on maps having large/complex submodels. Restructured the main loop in R_DrawBEntitiesOnList so that there are a few less levels of code indentation there. Signed-off-by: Kevin Shanahan <kmshanah@disenchant.net>
