An idea off the top of my head: Instead of a flat billboard, you could make a
simple low-rez height_field for the tree (including the trunk too, possibly).
Perhaps 2 or 3 different ones, for variation. (Pre-#declare each HF so that it
doesn't take up 'extra' memory when used repeatedly.) Then the trees would show
some highlights, using phong or whatever.
Since your current billboard scheme has the trees always facing the camera, the
same scheme would be used for the HF 'shells'-- the 'rear' or underside of the
HFs would never be seen.
