Marker onClick or onHover event? #49

Hi, is there any way to know when a marker was clicked or hovered over? I want to display a custom tooltip when a marker is clicked, wondering if this is possible with cobe

Sorry, but I don't think that will be possible without significant changes to the project design.

One thought about a work around: Use .getImageData() to detect a color similar to the marker, assuming they're a different color than the rest of the globe. Note that using this isn't very performant so it's probably best not to do every pointermove event or something like that.
