angleitem for point symbols

[Francesco Sozzi]

Hi Jeff,

Thanks for answer.

I add only a brief note to mail-list to say that rotating symbol is 
absolutely mandatory for several subjects.

For instance a "T" valve (symbol is a "T") if not rotated along the pipe is 
not readable in many cases.
Or street vertical signal if not rotated makes the map much more difficult 
to read.

For my experience (about 10 years in Italy and Switzerland), many users does 
not want gis engine without rotation capabilities.
Mapserver is a very good product, but without point rotation it is 
unfortunatelly too much limited for many subjects.

Best regards

Francesco Sozzi
