Bevel path node

[0HyperCube]

Add a node to bevel some vector data.

For each point in a path that is connected to exactly 2 segments:

• If the tangent of the ends of the two segments are scalar multiples, discard.
• Otherwise, offset by the user specified amount into both segments and insert new points.
• Delete the original point.
• Connect the two new points with a straight line segment.

Not in scope:

• Cleaning up paths where bevels overlap.
• Bevelling only particular points (possibly selected in the viewport by the user).
• Dealing with mesh paths (beyond ignoring points with >2 segments).
