[mapguide-internals] MapGuide RFC 55 - Switch from PROJ4 to CS-Map coordinate system library

[Kenneth Skovhede, GEOGRAF A/S]

Given the previous detailed information on compiling MapGuide with 
PROJ.4 support, would
it be possible to provide a compiled MgGeometry.dll with PROJ.4 for 
download and use with 2.1?

Or possibly the other way around, provide the compiled CS-Map MgGeometry 
dll as an add-on?

If suggestion 1 is chosen, it is possible to make a low-impact upgrade, 
with limited dedication from OSGeo.
Most user will just upgrade, and hapilly use CS-Map without observing 
the difference.
The unlucky users, can either deal with the problems, or postpone them 
for the 3.0 (or 2.2 relase),
but be aware that the problems are there.
