* Rename "FOV Mode" to "Sensor Fit"
* Add sensor height back in presets, default to Horizontal fit for all presets
except Blender, which uses Automatic.
* Some UI tweaks
===========================
Changes into sensor size use case.
There was problem with vertical sensor size which can't actually
affect on things due to we've got fixed image resolution. So
as soon horizontal size gets defined, both of sensor height
and vertical FOV is known and exposing it into UI makes things
difficult to understand.
That's why vertical sensor size was dropped.
Also added pixel aspect to camera settings fo clip editor.
Solver will sue this value rather than value from display
aspect ratio.
This pixel aspect would be copied to render settings after solving
so things should match now between footage, solving anf footage.
===========================
Commiting patch #24427: Editable camera sensor size (meaningful focal length units)
Thanks to:
Matt Ebb (author of original patch)
Ejner Fergo (porting patch through versions)
Brecht Van Lommel, Dalai Felinto, Campbell Barton (patch review)
Cant't commit changes to addons (they aren't branched, so some of them
could be broken now)
