Drop linetos smaller than tile resolution before doing normal simplification
...
Since simplification is rather expensive

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.
