Re: NavigatePanel setPanFactor

Hi Chris,

I think I remember looking at this a while ago, and there was some
problem with a mismatch in units. The NavigatePanel method wants some
number that is basically a percentage of screen to pan, and the
projection wants decimal degrees. I think getting the NavigatePanel to
figure out how to calculate decimal degrees for a pan amount was
something I didn't have time for.

NavigatePanel needs to become a ProjectionListener so it can use the
latest projection to figure out how many decimal degrees in a certain
direction the map should be moved, based on a current screen width
percentage.
