Do argument surgery for times when you don't really know what you are intersecting

circle

• Vec2-like and a scalar
• Circle2 - obj.position and obj.radius (which may be a function)

segment

• 2 Vec2 like objects
• 2 arrays
• x1, y1, x2, y2

line

• 2 scalars (slope + yintercept)
• Line2 signature

polygon

• obj.points
• array of
  • Vec2-like objects
  • [x,y]

It would be really cool if there was a parameterized function exposed by each of these primitives that didn't care what they were. Then intersections and potentially other things become circle.solve(line.equation.bind(line)) where .equation is a function to be called by the circle "solver".

Sounds complicated.
