[OGDev] Could maps be centred and scaled

[Andrew Black - lists]

I have a suggestion concerning maps (eg map of all points in a 
category).  I would like to get the maps to be centred and scaled.
For example, in the following, all the points are off the displayed map.
http://london.randomness.org.uk/wiki.cgi?action=index;format=map;index_type=locale;index_value=Carshalton

The following is a quick demo to play with 
http://www2.black1.org.uk/~andrew/map/exp_bounds.html
Click on a few points, hit "Reposition map" then repeat.

In practice
  - you might want to make it configurable for the user
  - apply a minimum zoom (eg my demo produces a very large scale map
    if you give a single point)

What do people think.
