[OSM-dev] slippymap doesnt wrap around +-180deg

[Luka Frelih]

hello!

i just noticed that our slippymap resists crossing the 180 degree 
meridian (intl date line).
try zooming in on new zealand at this link: 
http://www.openstreetmap.org/?lat=-41.47&lon=-179.23&zoom=6

i guess this is unintended. not sure whether we inherited this bug from 
openlayers or introduced it ourselves. either way i guess someone here 
will know what's going on.

best,
LF
