Hello!
OpenLayers.Map has three functions that look like being used for freeing
memory:
destroy(), unloadDestroy(), updateSizeDestroy().
Am I supposed to explicitly call them or not? From the description of
"unloadDestroy"
<http://dev.openlayers.org/docs/files/OpenLayers/Map-js.html#OpenLayers.Map.unloadDestroy>,
for example, it seems that it is already called by something.
I'm looking something similar to Google Maps' GUnload
<http://code.google.com/intl/lv/apis/maps/documentation/javascript/v2/reference.html#GUnload>,
which is supposed to be run upon page unload event - is there something
similar needed for OpenLayers?
Thanks!
