Is camera:begin needed

[ObaniGemini]

Camera end is useful to cut camera under the water, but is camera begin a necessity ?
It seems to cause some problems with lookaround feature when tweening entering and exiting of the mode. Is it worth being kept ?

Well, given that we use camera begin and end only for y-axis cutoff, I would be for dropping both, and making use of the acid-level detection in leve_holderl.gd, which is already present.
