Comment (by tschaub):
A fun exercise while considering dateline wrapping is to draw lines with
Google's "My Maps". If you zoom way out, things start out well as you are
given 360 degrees to play with. When you stray beyond the initial 360,
your point wraps to the other side of the map though your cursor stays
fixed. As you add points and pan, it looks like this 360 degree window
shifts, always giving you a good bit of room to add points. Things
quickly fall apart however if you start adding points at zoom 0 or so,
then zoom to 2 or 3 and keep adding points. Points are orphaned, lines
fall apart, and things get crazy. Similar craziness ensues when modifying
polygons that wrap.
