it's not a typical APS-C sensor, proper size gives more accurate
calculations.

The 22mm as stated on the lens is actual, not 35mm equvalent as on smaller
cameras.  - So it was wrong to reverse calculate for crop factor.

(the name was already the longes one)

Also change Plan Element selection ui

- GeoFence support comes from plugin
- Circle fence support
- Better param support

rearrange layout

camera model and sensor size closer together
