vector symbol origin not collocated at POINT?

[Charlton Purvis]

Hi, all:

Is there any way to have the starting point of a vector symbol as its origin
rather than the center of the final vector?  I have looked on the symbols
page as well as carto how-to and can't seem to find an answer.

I want to avoid having to compute offsets because I eventually want to
rotate these items.  And that wreaks havoc on those offset #'s.

See the attached image.  The circle is at POINT(x,y).  No problem.  But so
is the *center* of the vector.

The little vector is defined as:

SYMBOL
  NAME 'ln'
  TYPE vector
  POINTS
    0 0
    0 1
  END
END

But I guess (0,0) from the vector definition above doesn't really mean the
same thing as POINT(x,y)?

The circle symbol is the standard:

Symbol
  Name 'circle'
  Type ELLIPSE
  Filled TRUE
  Points
    1 1
  END
END

I want to avoid using a true type symbol if possible (since I only want it
to grow in length -- not width) or saving something like the attached as a
bitmap symbol because that messes up the crispness of the black edge when
transparency arrives on the scene.

I did poke around the listserv but found nothing apropos.

Many thanks,

Charlton
