1) Remove dependency on the /sim/rendering/shader-effects 2) Fix http://code.google.com/p/flightgear-bugs/issues/detail?id=494 where toggling the random vegetation on, iff initiall set off, did not generate new random vegetation. Fixed by forcing a tile reload in the same way as used for random objects.

<!-- Effects files for trees, which are placed by a shader. -->

<!-- Trees are drawn in two passes. The first draws the opaque parts
|
|
with z writes enabled. The second draws the the transparent bits
|
|
with z testing enabled and z writes disabled. The transparent
|
|
tree silhouettes will blend correctly against the opaque
|
|
geometry. They may cause artifacts when blending against other
|
|
edges, but the overall "forest" is supposed to be nice and
|
|
fuzzy. There might also be artifacts when blending over other
|
|
transparent objects, but that's mostly unavoidable.
