This file needs some serious work still, it will definately need the most work before dynamic bootstrapping works.

Note: This changes how Drupal.gmap.setup works! You now need to call it in the context of the map div if you're making maps dynamically (Which isn't officially supported by me yet.)

Also followup jslint for D5 specific stuff.

Also, I changed some % to %%. Although this wasn't a problem in practice, using a single % means relying on internal behavior of db_query.

Fix variable usage bug. It hasn't caused problems because the backwards compatibility variables are still being used as a fallback.

#349318, reported by jeeves: Fix empty map being displayed for 0.00,0.00 locations. (And add a backwards compatibiliy file so I can use location_has_coordinates().)

* Clarify what the first option for the marker does.
* Fix unsetting a marker deliberately
* Fix several bugs with updating marker associations after changing a term.
* Fix SQL error when setting a marker on existing terms.
* Add function to recompute markers after changing a term.

add a class around map bubble contents. you can now set width and height on .gmap-popup in your css and map bubbles will grow to fit it.

* Allow multiple locations for users and nodes.
* Fix marker titles and give them sane values.
* Add offset to make markers with multiple images work as expected.
* Rewrite gmap_location_author_block_view() to work similar to gmap_location_block_view().
* Remove hardcoded 'gmap_location_authorblock' mapid to match the behavior of the node block. (Reassign it in the macro if you need it.)

#350408 by pillarsdotnet: Selecting "Regenerate marker cache" does not reliably clear and rebuild the marker cache.

gmap_regenerate_markers()

    * Pass TRUE to the gmap_get_icondata() function
    * Pass TRUE to the gmap_set_marker_titles() function

gmap_set_marker_titles()
