+ // Curve converter class. Any path storage can have Bezier curves defined
+ // by their control points. There're two types of curves supported: curve3
// and curve4. Curve3 is a conic Bezier curve with 2 endpoints and 1 control
// point. Curve4 has 2 control points (4 points in total) and can be used
- // to interpolate more complicated curves. Curve4, unlike curve3 can be used
- // to approximate arcs, both circular and elliptical. Curves are approximated

- // sequence of vertices that approximate our curve. It takes additional

// Initially, path storages are not suppose to keep all the vertices of the

- // are marked with special commands. So, if the path_storage contains curves
- // (which are not real curves yet), and we render this storage directly,
- // all we will see is only 2 or 3 straight line segments (for curve3 and
- // curve4 respectively). If we need to see real curves drawn we need to
- // include this class into the conversion pipeline.
