Alignment of TrueType label is not beautiful.

[gis@…]

In the label display processing, the position has been
decided based on the rectangle obtained by GD. 

there is no problem when the character string is usually 
displayed. 
but, When the character string is displayed by one character
one point, it is not so good.

I wrote the explanation patch.

      msSetError(MS_TTFERR, "TrueType font support is not 
available.", "msGetLabelSize()");
      return(-1);

I think that this is not so good solution. accuracy is bad. 

IMHO, we would make align method can chosen by the POSITION
parameter of MapFile to make it not influence an existing user.
