[motion] direction and starting point of circle/ellipse

Hi,

forwarding on behalf of Eric Willigers, who found some inconsistencies in  
how the starting point and direction works in the motion path draft  
compared to svg2. In the definition of the motion-path[1] property the  
starting point and direction for circle and ellipse are different to the  
ones used for the equivalent paths in svg2, see [2][3]. In svg the  
equivalent path for circle and ellipse starts at 3 o'clock and proceeds  
clockwise.

Is this going to be a possible cause of confusion, and should these  
definitions be aligned?
