Ballistics approximation

Not for Urho, but might help people working with projectiles in their projects: https://www.patrykgalach.com/2020/03/23/drawing-ballistic-trajectory-in-unity/

Helped me a lot in my game!

Since you’re basically drawing a parabola, it might be useful to have a Plotter struct that generates a vector of Vector3Ds which could then be used to generate the desired geometry through a RibbonTrail subclass. This approach would extend the applicability of your classes while providing more control by separating the shape and resolution of the curve from how it is displayed (if at all).
