Adds projection test for world-to-screen consistency

Browse Source 
Adds a test to verify the consistency of world-to-screen and
screen-to-world projections. This ensures that projecting a point
from world to screen and back results in the same point, thereby
validating the correctness of the camera projection transformations.
