Hm. The reason I decided on blobs is that that is what the other
tree-generators I found use. I figured they'd go with a mesh or an
isosurface, but they went with blobs.
The leaves are not part of the blob, btw... separate triangle-based objects.

Thank you for the suggestion, I may end up doing that if I can't get
something satisfactory out of this.
