19.147 draw:enhanced-path

From Thorsten Zachmann, originally posted to office list: http://lists.oasis-open.org/archives/office/201012/msg00195.html

while working on the 19.147 draw:enhanced-path, the question came up if the arc for the commands U and V is clockwise or counter clockwise. Can anybody shed some light into this.

Here the text for the commands U and V.

U
angle-
ellipse
(x y w h t0 t1) +
The same as the "T" command, except that a
implied moveto to the starting point is done.

V
clockwis
earc
(x1 y1 x2 y2 x3 y3 x y)+ The same as the "A" command, except that a
implied moveto to the starting point is done
and the arc is drawn clockwise.
