```
    High-level function that tessellates a series of curves into triangles, where each spine is a series of chained cubic Bézier curves.
    The first curve of each spine is defined by an endpoint, followed by two control points, followed by an endpoint. Every subsequent curve in the spine is defined by a single control point followed by an endpoint. Only one control point is required because the first control point is computed via reflection over the endpoint.
    
    The number of vertices in each spine should be 4+(n-1)*2 where n is the number of piecewise curves.
    
    Each spine is equivalent to an SVG path that looks like M C S S S.
