Clean up the gamma semantics a little.
...
0 (default) means unchanged: maxzoom contains all the dots.
Positive number, even very small, means that it still checks
the gap size and thins out dots if they are close together.
Negative number means no gamma, and the old random instead of
uniform dropping at low zooms.

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.
