Change some defaults that keep tripping people up:
...
* Default detail with low -z is only 13, so it works with GL
* No coalescing, line-reversing, or reordering by attributes except by request
* Dropping lines like points moves from -d to -a

Trying to follow Vlad's suggestion and work from the top down.
...
Doesn't quite work yet, but seems like the right thing to do.
From the bottom up, indexing is a mess because of the buffering,
and includes unneeded areas in the bounding boxes of big features.
