changeset 6119:0b9f0d37fe6e
We have a much faster interactive image map!
* Image for highlighting rivers in link list instead of CSS manipulation.
* Better event handling.
* No more hover delay.
Some problems still exist:
* Sometime when switching the module to 'MINFO' the highlighted river on the
image map is not unhighlighted.
* The loop to unhighlight rivers when switching modules is called for every
river.
