/**
* gsk_path_builder_svg_arc_to:
* @self: a `GskPathBuilder`
* @rx: X radius
* @ry: Y radius
* @x_axis_rotation: the rotation of the ellipsis
* @large_arc: whether to add the large arc
* @positive_sweep: whether to sweep in the positive direction
* @x: the X coordinate of the endpoint
* @y: the Y coordinate of the endpoint
*
* Implements arc-to according to the SVG spec.
*
* A convenience function that implements the
* [SVG arc_to](https://www.w3.org/TR/SVG11/paths.html#PathDataEllipticalArcCommands)
* functionality.
