 This still leaves the lower zooms too dark (and too dense for the 500K tile limit,
 in some places), so I need to figure out an equitable way to throw features away.

+any polygons that are smaller than a minimum area (currently 4 square subpixels) will
 have their probability diffused, so that some of them will be drawn as a square of
 this minimum size and others will not be drawn at all, preserving the total area that
 all of them should have had together.
