[Improvements] Camera

[mrvux]

UI Implementation unclear

• Allow to set either by Interest(LookAt as now), Orientation (for pinhole simulations), Direction
• Fov to be configurable (Also allow focal length instead, which is more widely used).

Unclear how (technically) / or what it means

• Aspect Ratio should be optional (enabled by default), some cases require to disable it.
• Allow to work in reverse depth mode

Things that are already possible

✔ Allow to set a custom view/projection matrix (can always derive back most parameters from it). ✔ Near / Far should be configurable (can drastically improve some post proc, needed to fit shadow maps too) ✔ Lens shift (extremely useful for projector simulation). ✔ Allow to switch between perspective and ortho (ortho is important for shadow maps).

possible through workarounds

[ ] Add Coc factors (Depth of field) -> set in DOF Operator

Some excellent suggestions here.

I'm not sure how to break this up between different operators and context, yet.

I slightly edited and sorted the task.
