Begin a new sub-path. Note that the existing path is not affected.
After this call there will be no current point.
In many cases, this call is not needed since new sub-paths are
frequently started with cairo_move_to().
A call to newSubPath() is particularly useful when
beginning a new sub-path with one of the arc() calls.
This makes things easier as it is no longer necessary to
manually compute the arc's initial coordinates for a call
to moveTo().
