[Routing] video of pyroutelib2 routing, showing which areas of map data it downloads

[OJ W]

Hi. The resolution is terrible, but I did an animation of pyroutelib2 at work:

The original video file will be here for a while: (better resolution
etc., about 11MB)

http://dev.openstreetmap.org/~ojw/files/Video/pyroutelib2/

that's Godalming to Ashford (>90 miles), just for a sense of scale.
The blue rectangles show areas where it decided to download map data.
The yellow dots are the routes that it's considering.  So it seems
reasonably efficient in terms of what data is being loaded (the less
blue the better..)

p.s. the weightings file in SVN still loves trunk roads and considers
them as good as motorways (in case you're wondering why it didn't pick
the M25 that time)

p.p.s. aspect ratio is totally out -- the blue rectangles should look
square if you viewed them on a slippy-map.  I'll put a widescreen
version on dev later.
