[QGIS-Developer] Zoom to selected point (if only one point is selected)

[Denis Rouzaud]

Hi,

I guess that in terms of end user experience, the definition of a setting
would perform the best.
But
- it's one more setting
- the chance that it is not set or correctly set is big

Maybe, the approach would be to fetch the canvas content and determines
that ones needs to zoom out so that the symbol is not overlapping others or
that there is sufficient screen width from its neighbours?
