[ka-Map-users] Resizing map?

viewport based on the browser window size.
Here's another (possibly dumb) question - is there a way to calculate
latitudes and longitudes in the browser? I'd like to put some
elements that get loaded dynamically (from a 3rd party service) via
XMLHTTPRequest over the map, but can't seem to figure out how to
position them correctly. I realize this may be more of a general
trig question, and not something specific to ka-Map, but maybe
someone has done this before and could help me out.
So, given an array of lat/long coordinates, I'd like to (in
1) Convert the lat/long to pixel offsets
2) Test if the current viewport contains the point
3) If so, add an element to the page at the proper offset.
1 and 2 are what I'm having trouble with. #3 is easy enough (i'll
track the dynamically created elements and move them along with the
rest of the tiles)
Anyone have any suggestions?
