Eric Fischer 028fef470e Fix the major bug: forgetting to offset back to world coordinates 2014-12-04 14:08:36 -08:00
Eric Fischer 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.

Eric Fischer cc58588724 More sensible error message when there are no valid geometries 2014-11-24 22:50:12 -08:00
Eric Fischer 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.

Eric Fischer 241d96e57c Save a few more bytes per geometry in the temporary file 
by using bytes instead of ints for the drawing operations

Eric Fischer c24cfada61 Move feature type to index so point skipping can avoid looking up geometry 
Which should avoid having to page the geometry in if there is
more data than will fit in memory

Eric Fischer 4b171c74b7 Constrain calculated center point to be within the bounding box 
It could come out bigger because it is calculated from the center
of the densest tile, not actually the centroid.
