Adds a new shader example showing how to sample a texture with screenspace coordinates, similar to the end [portal in minecraft](https://bugs.mojang.com/secure/attachment/163759/portal_frame_112.gif). https://user-images.githubusercontent.com/22177966/156031195-33d14ed8-733f-4d9e-b1da-0fc807c994a5.mp4 I just used the already existent `models/FlightHelmet/FlightHelmet_Materials_LensesMat_OcclusionRoughMetal.png` texture but maybe we should use a dedicated texture for the example. Suggestions welcome. Co-authored-by: Carter Anderson <mcanders1@gmail.com>
