++
++1. this is going to be a pain in the arse. it fixes things like light `beams` from being cel'd but it
++also will ignore any other shader set with no culling. this usually is everything that is translucent.
++but this is a good hack to clean up the screen untill something more selective comes along. or who knows
++group desision might actually be that this is liked. if so i take back calling it a `hack`, lol.
++	= bob.
++
++2. mirrors display correctly because the normals of the displayed are inverted of normal space. so to
++continue to have them display correctly, we must invert them inversely from a normal inversion.
++	= bob.
++	
++3. this turns off a lot of space hogging sprite cel outlines. picture if you will five people in a small
++room all shooting rockets. each smoke puff gets a big black square around it, each explosion gets a big
++black square around it, and now nobody can see eachother because everyones screen is solid black.
++	= bob.
++
++4. ignoring liquids means you will not get black tris lines all over the top of your liquid. i put this in
++after seeing the lava on q3dm7 and water on q3ctf2 that had black lines all over the top, making the
++liquids look solid instead of... liquid.

++
++1. this is going to be a pain in the arse. it fixes things like light `beams` from being cel'd but it
++also will ignore any other shader set with no culling. this usually is everything that is translucent.
++but this is a good hack to clean up the screen untill something more selective comes along. or who knows
++group desision might actually be that this is liked. if so i take back calling it a `hack`, lol.
++	= bob.
++
++2. mirrors display correctly because the normals of the displayed are inverted of normal space. so to
++continue to have them display correctly, we must invert them inversely from a normal inversion.
++	= bob.
++	
++3. this turns off a lot of space hogging sprite cel outlines. picture if you will five people in a small
++room all shooting rockets. each smoke puff gets a big black square around it, each explosion gets a big
++black square around it, and now nobody can see eachother because everyones screen is solid black.
++	= bob.
++
++4. ignoring liquids means you will not get black tris lines all over the top of your liquid. i put this in
++after seeing the lava on q3dm7 and water on q3ctf2 that had black lines all over the top, making the
++liquids look solid instead of... liquid.
