[OpenLayers-Dev] Understanding the restrictedExtent code.

[Andreas Hocevar]

You're talking about the Map's moveByPx method? The side effect would
be that people could drag past the restricted extent, and then the map
would jump back to the restricted extent. So a bit more effort would
be required to make dragging work on restricted extents that cross the
dateline.
