As a side effect, this means that using a location_cck relationship will now do the right thing for a gmap view.

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

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

gmap_set_marker_titles()

    * Simplify and correct the caching logic

gmap_flush_caches()

    * Add an implementation of hook_flush_caches to ensure that clicking on the "Clear cached data" button from the /admin/settings/performance page also rebuilds the marker cache.

Add shape clickability.

Keep track of a per-map storage handler variable. It can be accessed if needed by adding a second parameter to the callback function.

Brown paper bag fix. I broke hyphenated mapids back in September and it took me this long to notice.

Fix #345269, noticed while helping George2 in IRC: Call node_view() instead of theme('node') to make stuff like CCK fields get output correctly in node markers.

#336995, reported by skyredwang: Disable caching for gmap_location blocks, because they do dynamic things.

Commit this while I'm in the middle of it because I'm really happy with it so far and I don't want to lose it. ;)

#330343, reported by fabio84 and also by epimeth in irc: Make script url valid again, I forgot that url() returns raw ampersands.

Let people pass map arrays to theme('gmap') without wrapping them in array('#settings' => ...). In theory.
