The unit tangents at the points t === 1 of the first curve and at t === 0 of the second respectively.
The cross of the unit tangents.
True if the corner is sharp, i.e. > 0 radians as one goes in a positive direction around the shape boundary.
True if the corner is dull, i.e. < 0 radians as one goes in a positive direction around the shape boundary.
True if the corner is quite sharp, i.e. > δ radians as one goes in a positive direction around the shape boundary where δ is some pre-determined parameter.
True if the corner is quite dull, i.e. < δ radians as one goes in a positive direction around the shape boundary where δ is some pre-determined parameter.

Represents a corner on the shape boundary, i.e. a point where two bezier curves meet. This class is typically used internally only.
