Display the absolute value of the inclination at the bottom of the screen, as the pitch value and compass direction

[Robert Tuker]

OpenCamera express the inclination using horizontal lines each 10 degrees on the preview.
It would be amazing if this could show the absolute value of the inclination at the bottom of the screen, as this shows the pitch value and compass direction (see the attached image).

This is useful to make height measurements, as it is done using mechanical clinometers:

For now I have to use a proprietary software as a clinometer, but if I could see the degrees in OpenCamera I could use this as my official open source clinometer, and measure the height of rock ourcrops and trees in my work.
