[mapserver-dev] RFC 101: Content Dependant Legend Rendering

Hi Thomas,

Nice addition. I can envision this being very useful with HTML legends 
eventually even if I undertsand that this may be out of scope for you now.

BTW, we may also want to support this with legends embeded in the map, 
or in an HTML template from the traditional CGI or even MapScript. In 
this case since we already call msDrawMap() for the main map, we could 
avoid two passes on the data if msDrawMap() could do the marking of the 
layer/class/style/labels on the fly instead of having to make a separate 
call to msHitTestMap(). Would this be easily feasible?
