Gets a matrix for a hit point on the screen. The hit point is given in relative screen coordinates (X and Y component, 0..1). The screen's aspect ratio is given in the Z component.
The result is a matrix which transforms world coordinates in that way that the hit ray in world coordinates is transformed to x=0 and y=0 and z being the distance to the camera.
