Enabling standard Godot 3d viewport navigation

[jcarlosrc]

Feature/enhancement description: It seems like mesh preview only accepts rotation values. This makes material preview hard on some meshes. I cannot see any reason not to have full godot navigation enabled to visualize the mesh as desired.

The 3D editor's navigation code isn't exposed to projects, so it would have to be reimplemented from scratch.

In current dev version, you can right-click on the object and select the "center on clicked surface" menu to center the view on a specific part of the mesh (which is generally what you want to do when creating a material).

Well, as I understood this issue is all about panning the view, right? Or do you mean a full adaptation of Godot's viewport navigation?
