MAXIMGSIZE in mapfile

[Steve Lime]

There is a MAXSIZE parameter in the map object already that serves this purpose if
I am not mistaken. It sets the maximum number of pixels in either image dimension
and defaults to 1024. Both the CGI interface and WMS validate against it. It cannot
be changed via URL. It's in the mapObj reference file...
