*Fixed OpenGL's handling of cv_translucency effects (should not remove shadows if off, but perhaps make them use default alpha?), someone was a bit hasty! *De-stupified the MD2 status checks regarding drawing of sprites - if they're already checked before calling HWR_DrawSprite, there's no point doing them WITHIN the function as well *Split off sprite shadow code into HWR_DrawSpriteShadow for convenience
