[mapguide-users] MGOS 2.1: Failure with dynamic coordination transformation

Transforming between XY-M and a real CS is not technically possible; the
previous version must have been "guessing" that the XY-M dataset was in the
same projection as the other datasets.

My bet is the change from PROJ.4 to Mentor as the underlying CS library
makes this a bit stricter, requiring you to manually specify the CS for the
arbitrary data before attempting to transform it (or not).
