    Using the same
    parameters, XDrawArc draws the appropiate arc, while XFillArc fills something
    different.

You don't say how they are different, so one can only guess.  The semantics
of the two are indeed different, the "edges" will not be coincident (depending
on the line-width and the exact arc) because of this semantic difference.
Try staring real hard at the protocol definitions.
