[Algorithms] ProgMesh LOD function.

[Timur D. <ti...@3d...>]

I`m trying to come up with good lod function for progressive mesh reduction,
i have all progressive mesh collapses precalculated so can`t use per vertex
screen error function,
i need something more general for complete mesh, function which says how
many percents of mesh should be cut down
currently i just taking screen space area of mesh bounding box, dividing by
some kludge const, but it works badly for different mesh scales.
any ideas?

  regards.
