[OpenLayers-Users] VisibilityChanged event handler

[Dmitri Mizerkin]

I'm afraid the "changebaselayer" event won't help me out, because all the
selectable layers I use are overlays.
So there's no way to do it, is there? Well, I'll look for a workaround, but
it would be great if this feature was in the newest release.

Thanks anyway!

Cheers,
Dmitri
