Map Widget Futures

I'm not quite sure what you mean by 'a member of the msg path in "proper
standing"' - the map widget just wraps a native view essentially. The map
'object' is only accessible through foreign handlers in LCB, but if it can
be done natively then it can be done.

In the first instance the widget will support annotations/markers and
polylines, but won't support generic overlays.

Just thinking aloud for a second, one way we could potentially make that
work, and make the map widget a lot more flexible on the objective-c side
is to allow custom implementations of the map delegate in LCB. This would
enable you to write the appropriate callbacks to do custom overlays. I
can't think of a particularly nice way to support overlays as a basic
property, but that might just be because I haven't thought about it enough.
