Map extent in MapScript

[Stephen Lime]

Here's the symbol (can be in mapfile or symbol file)

 SYMBOL
    NAME 'circle'
    TYPE ELLIPSE
    FILLED
    POINTS 1 1 END
  END 

and here's a class definition (note the use of overlaysymbols)

  LAYER
    NAME majrdln3_interstate
    GROUP roads
    MAXSCALE 600000
    SYMBOLSCALE 200000
    STATUS OFF
    DATA shapefiles/majrdln3_interstate
    TYPE LINE
    CLASS      
      COLOR 121 0 0
      SYMBOL 'circle'
      SIZE 5
      MINSIZE 3
      MAXSIZE 7
      OVERLAYCOLOR 181 51 51
      OVERLAYSYMBOL 'circle'
      OVERLAYSIZE 3
      OVERLAYMINSIZE 1 
      OVERLAYMAXSIZE 5
    END
  END # interstates

This is from the LandView interface (maps.dnr.state.mn.us/landview/).

Maybe I should shout a 'RTFM!' at myself. I was staring on my printouts for
about half an hour because I could not believe that such a method did not
exist. Now I found it. After you pointed it out. I am getting old.

But here is another one I could not figure out. I tried to use the 'STYLED'
symbol type, which is documented but does not seem to exist anymore, neither
does it appear in the source code. I would like to use lines with a width of
more than one pixel, and really love to create things like a highway with two
solid side lines and a dashed center line.
