Eukara 9099d2796b Always sample lightgrid a bit higher up, because anything close to the 
ground usually turns pitch-black that's got a smaller bounding box.

//a note about dedicated servers:
//In the server-side gamecode, a couple of q1 extensions require knowing something about models.
//So we load models serverside, if required.
//things we need:
//tag/bone names and indexes so we can have reasonable modding with tags. :)
//tag/bone positions so we can shoot from the actual gun or other funky stuff
//vertex positions so we can trace against the mesh rather than the bbox.
//we use the gl renderer's model code because it supports more sorts of models than the sw renderer. Sad but true.
