A bit of harmless cleanup, null checking, nan checking. Removed sphericalProjection and cylindricalProjection from llface (broken/dead).
Removed CLEAR_INVISIBLE drawable flag.
Added some missing drawpool determination logic pertaining to face materials.
Fix issue displaying material faces with a shine value applied when performing deferred rendering. Also attempt to fix rigged material faces when performing deferred rendering (Todo: test rigged mesh material+(shiny|alpha|alphamask|fullbright) combinations)
