CairoContext::closePath -- cairo_close_path — Closes the current path
Adds a line segment to the path from the current point to the beginning of the current sub-path, (the most recent point passed to CairoContext::moveTo()), and closes this sub-path. After this call the current point will be at the joined endpoint of the sub-path.
The behavior of close_path() is distinct from simply calling CairoContext::lineTo() with the equivalent coordinate in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead, there is a line join connecting the final and initial segments of the sub-path.
If there is no current point before the call to CairoContext::closePath(), this function will have no effect.
