It would take if I render with area_light and 3D tree model. To make it
faster I use a blank png with a tree silhouette in alpha channel mapped
to a pair of triangles. For soft shadows I blurred the alpha chanel in
Photoshop, much faster and better results than with area_light. It took
about 5 minutes on 1GHz Athlon.
