b068635acf Elevation in geometry is a warning, not an error.

08ff40e42f 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.

ffe4c95376 Calculate point dropping during encoding instead of tiling 
so it is consistent across tile boundaries, and so every point
that exists at zoom x always also exists at zoom x+1.
