Fix: fix for lighting equations , that must improve lighting in a lot of games (  test smg :) )
experimental speedup: implemented alpha pass using stencil buffer instead of a duplicate shader. i recommend to test this well as i dono if will work the same way in all the systems. i my system it gives a nice 2-5 fps improvement. if it brings problems in any system or game will revert asap.
enjoy
