[mapserver-dev] WMS Client Layer Development

In an effort to address problems with cascading via a layer type of WMS
to remote WMSes with restricted areas of effective operation, in potentially
very different projections I am going to do some work on mapwmslayer.c.

In particular, it currently always generates a request to the cascaded WMS
with the same width and height in pixels as the original request, essentially
just trying to re-express the BBOX of request in the coordinate system of the
remote WMS.  I intend to remove this assumption.

I am also planning to add optional metadata on WMS layer that can be used
to express it's effective area limits.

This is related to ticket:


This is mostly a warning to those who work on mapwmslayer.c that significant
changes are likely to come through and they can speak up now if they think
my ideas is lame.  Based on svn blame the main past contributors to this
module seem to be Daniel, Assefa, Steve, Tom, Paul, Julien and myself.
