IDEA: Add incremental steps to camera and view manipulations - grid style

Is your feature request related to a problem? Please describe.

No Problem involved, just a nice to have :)

Add a way to define incremental values to 'snap' the views and camera orientations when manually moving and dragging the POV to align to certain orthogonal set points (and maybe add detail in status bar for angles snaps and viewpoints?)

Describe the solution you'd like
A way to optionally (or default) snap increments for camera and viewpoints (1, 5, 10, 15 degrees) to help with setting the camera to specific angles and rotations for edition etc)

Describe alternatives you've considered

Details:

Two leocad instances - left is top view, right is back view (of transformed model in a different file)

when rotating the view on the left to align to the one on the right, snapping would be good to make sure it is perfectly orthogonal and aligned.
