Cast ray from any given point on screen, not just from the pointer position

[CabeDigicorp]

Description 📝

Currently, the SimpleRaycaster.castRay() method casts a ray from the camera to the mouse or touch event point. There is no way to override the mouse/touch position and cast to a point defined by its (x,y) on-screen coordinates.

Suggested solution 💡

In the Core module, modify the SimpleRaycaster.castRay() method so that it accepts an optional parameter of type Vector2. If that parameter has a value, use it as the raycasting point; otherwise, use the mouse/touch position as in the current implementation.
