d3d: remove the depth texture path it will not work so for now only lockable textures were available. i thing the only way will be a use a secondary render target and do a depth pass to mimic depth textures.
opengl: minor cleanup here and there and a possible fix to issue 1509, but not tested because in my system the errors remarked in the issue don't show.
commond: code reorganization an optimization in the pixel shader generator, trying to understand the tev stages, make some changes to make the generator faster (not much only started for the alpha test and fog).
this changes try start solving the diferences bethen the hardware plugins and the soft plugin.
i hope with i don't brake nothing but please test this a lot.
