/**
* This shape offers star-like shapes with a lot of parameters :
*
* Types :
*
* Star - fully connected star shape.
* Star outline - like star but without the cross connections.
* Framed star - like star outline but with an enclosing path.
* Spoke - basically a star outline with inner radius of zero.
* Wheel - like spoke but with enclosing path.
* Polygon - like VPolygon.
* Gear - variant on star outline, resembling the KDE gear.
*
* Parameters :
*
* Edges - number of edges, which must be greater or equal to 3.
* Outer radius - radius amount of circumcircle of the star.
* Inner radius - inner radius where star has to connect to. This value
* doesn't apply to polygon, spoke and wheel.
* Inner angle - extra radius amount for inner radius.
* Roundness - uses curves instead of lines for the star shape.
