Improve look down angle to support OG behaviour

[Richard-L]

In light of #1338 there was:

20250112-2300-10.2117706.mp4

If there should be a way to restore the OG look angle, whilst also taking care of the camera flipping on the way back, it would be ideal.

Just for reference, the new angle was chosen from TR4. That seemed to be more OG than choosing an arbitrary value.
