Mercator Projection
-------------------
Figure1.13.

The Mercator projection. Shown are the projections of circles of constant
radius 10 degrees across the sky. Note that the area is not preserved by the
Mercator projection: the projection increases the size of finite regions on
the sphere, with a magnitude which increases at high latitudes.
