/**
* SECTION:cogl-paths
* @short_description: Functions for constructing and drawing 2D paths.
*
* There are two levels on which drawing with cogl-paths can be used.
* The highest level functions construct various simple primitive
* shapes to be either filled or stroked. Using a lower-level set of
* functions more complex and arbitrary paths can be constructed by
* concatenating straight line, bezier curve and arc segments.
*
* When constructing arbitrary paths, the current pen location is
* initialized using the move_to command. The subsequent path segments
* implicitly use the last pen location as their first vertex and move
* the pen location to the last vertex they produce at the end. Also
* there are special versions of functions that allow specifying the
* vertices of the path segments relative to the last pen location
* rather then in the absolute coordinates.
