[OSM-dev] Automated tracing (expanding scanaerial)

Scanaerial (a fork of Fuzzer) can't work with detailed data sources - it
analyzes changes in color, and it changes too fast on highly detailed data
sources. (Think 'Fuzzy select' from Photoshop-like apps).

You can change data URL in scanaerial config to any other WMS service, and
there are ways to make it work with Bing. Results are worse than with
landsat that was prepared for automated deciphering.

It's impossible to make it all better without major rewrite, and that has
to be done by someone with expertize in computer vision.
