yes, that's what ZoomToSelected normally does, it zooms to the selected
elements ;-). This means that one needs first selections, created with
the select tool. This button functionality was just added for
convenience in some cases, and it was implemented quite simply. In most
applications probably not needed anyway.

this means every click on a zoomto image (the magnifier) is treated as a
selection and modifies the PMap.extentSelectedFeatures variable. And
hence overwrites the extent value of the still selected features. This
is how I would interpret it (correct me if I'm wrong) and that's why I
don't see this as a very consistent behaviour. But one can customize
this function like that if needed and wanted.

But also in the current version there was a bug that caused exactly this
overwriting of extentSelectedFeatures when applying an identify. I
modified the pmjson.js->returnZoomParamsHtml() to avoid this. Committed
to SVN.
