[crossfire] GTK smoothing code

[Nicolas Weeger]

Hello.


I committed a small change to the GTK client smoothing code with revision 
14690.

The result of the sign change make ssmoothing look "more correct" to me 
(tested with burning hands spell)

I definitely and totally may be wrong, so please feel free to revert the 
change! :)


Regards


Nicolas
