Yup, works nicely here, there's definitely an improvement. I've also
modified the predicates for techniques 4 and 9 take that into account
I've also fixed the black hat by increasing the bleed margins in treebin.cxx
a tad:
t->push_back(Vec2(variety + 1.0f, 0.234f));
t->push_back(Vec2(variety, 0.234f));
I'm using the old square texture - that would need adjusting because those
margins clip the top of the higher trees.
All looking really good here now.
