cairoClosePath: cairoClosePath
Description
Adds a line segment to the path from the current point to the
beginning of the current subpath, (the most recent point passed to
cairoMoveTo), and closes this subpath.Details
The behavior of cairoClosePath is distinct from simply calling
cairoLineTo with the equivalent coordinate in the case of
stroking. When a closed subpath is stroked, there are no caps on
the ends of the subpath. Instead, their is a line join connecting
the final and initial segments of the subpath.
