Extension methods for Eto.Drawing.Point and Eto.Drawing.PointF

## Methods

- [Angle](https://developer.rhino3d.com/api/gh2/type/grasshopper2.extensions.pointextensionmethods/angle.md): (static) Gets the angle (in degrees, measured anti-clockwise) of a size, assuming it represents a vector.
- [Average](https://developer.rhino3d.com/api/gh2/type/grasshopper2.extensions.pointextensionmethods/average.md): (static) Create a plane halfway this plane and another.
- [DistanceTo](https://developer.rhino3d.com/api/gh2/type/grasshopper2.extensions.pointextensionmethods/distanceto.md): (7 overloads, static) Measure the distance between this point and another.
- [FindTangents](https://developer.rhino3d.com/api/gh2/type/grasshopper2.extensions.pointextensionmethods/findtangents.md): (static) Find the tangent lines from this point to a circle.
- [FindTangentsEx](https://developer.rhino3d.com/api/gh2/type/grasshopper2.extensions.pointextensionmethods/findtangentsex.md): (static)
