Several flaws with the Game's Camera

[Rusty-Box]

This issue serves to collect several aspects of our current camera system that really need a touch up or two.

• [ ] Peeking all directinons is rather slow and breaks camera movement
• [ ] Peeking also causes odd camera locking at sector edges
• [x] Zooming in manual mode is just plain broken camera and zooming looks also very jittery on slow speeds (see #2405)

Should there be more things found, they will also be mentioned in here!

The camera jitters a lot because it is synchronized to the "physical fps" (50 Hz) instead of the screen refresh rate (often 60 Hz). In addition to jittering, this synchronisation prevents players to avoid motion blur even on a high-refresh-rate display. If frames were generated synchronous to the display refresh rate, it would be possible to use a high-refresh-rate display with strobing backlights, which strongly reduces motion blur. #910

With d5ca4bf at least the camera zoom in manual mode has been solved. A great improvement. The issues with camera peeking still remain as of now.
