<2v rx,ry> <float rot> <int flag1> <int flag2> <2v x,y> <int num_verts> [z]

As the syntax above shows，ArcTo has 3 parameters（ float rot, int flag1 and int flag2 ） between the radius vector and the coordinate vecter.
I've found that the third(int flag2) can be used to set the direction of the arc(CW or CCW),but I can't find out what the other 2 parameters( float rot and int flag1 ) stand for and can be used to do.
It will be kind of you to tell me the answer, and thanks in advance.^_^

This node was intended to closely resemble the SVG style of specifying paths, and you should really look at what SVG specs say about ArcTo
