Filled vector symbols don't respect the -99 convention

[v@…]

From what I understood from the docs, specifying -99 (or a negative number) 
cuts a vector and starts another one. This only works for non filled vector 
symbols. If I set filled to true, the symbol draws the -XX point.

Compare:

SYMBOL
        NAME "carretera1"
        TYPE VECTOR
        POINTS 1 1 3 3 3 2 1 0 1 1 -99 -99 4 2 6 4 6 3 4 1 4 2 END
        FILLED FALSE
END

With:

SYMBOL
        NAME "carretera1"
        TYPE VECTOR
        POINTS 1 1 3 3 3 2 1 0 1 1 -99 -99 4 2 6 4 6 3 4 1 4 2 END
        FILLED TRUE
END

I'm currently using 4.4 beta1

Changed the maker, line and shade symbol routines to handle multi-part symbols.

reopening as the fix only looks for negative values in the symbol points, not -99 -99 (which is the penup value as referenced in the howto docs and mapsymbol.c .
