Transforms position from viewport space into world space.
Viewport space is normalized and relative to the camera. The bottom-left of the camera is
(0,0); the top-right is (1,1). The z position is in world units from the camera.
Note that it transforms a x-y screen position, into a x-y-z position in 3D space.
You provide the function with a vector where the x-y components of the vector are the screen coordinates and the z component is the distance of the resulting plane from the camera.
