Comment:
I'm not sure why this is happening, but it appears to have been a problem
for quite some time. Checking with 0.2.10, I see that even before any of
the recent map improvements, low zoom levels have wildly distorted
latitude calculations. After a fair bit of study, I can't quite figure
out why this is occurring with latitude and not longitude.
As a workaround, changeset:1425 adds a "fudge factor" value function that
measures the disparity when the zoom level is changed and uses it in
subsequent x,y calculations. This seems to mask the issue sufficiently
until a real solution can be constructed.
I'll mark this as "fixed" even though I'm not considering it completely
so.
