Thanks, I'll give it a shot and post the results. IIRC though when I tried  
a variation of this a couple of weeks back I kept getting the mapserver  
message: "Cartoline drawing is deprecated with AGG", so I figured that  
wasn't the correct way to do it. :-)

And I had not realised that *COLOR directives accepted a hexadecimal value  
as an alternative to R G B values!  That will make things easier.

As to the other implied question in my OP - since I've discovered that  
rendering with transparency on fixes a number of artifacts - so does  
anyone know of a solution for setting background when rendering RGBA tiles  
since IMAGECOLOR no longer seems to work?
