Reassign position and scale of the navigation gizmo in the will to build a -limited Blender edition- easy to use for 3D model visualization, I want to move and scale the navigation gizmo. It seems that is not declared in a python file.
I'm answering myself in case this helps anyone in the future. The file to edit is \blender\source\blender\editors\space_view3d\view3d_gizmo_navigate.
