>> How can we solve this issue? Here are my ideas:
>> a) QGIS points to a fraction (say 1%) of the overall width of all layers
>> in the project and uses that 1% width and pans to the point
>> b) The user can define a map scale that QGIS should use when zooming to
>> that single point
>> c) a combination of a) and b): if b) is set in the project, use the
>> setting, if not set, use the mechanism of a)
>> What are you thoughts?
