[Bf-interface] Viewport: User Interface proposal

[Dalai Felinto]

Hi there [*],

We haven't discussed UI (user interface) for the viewport yet. Even
during the Sprint we focused on the internal functionalities, as
opposed to how the user would access it.

There is a lot of overlap with the layer-manager work Julian Eisel
(Severian) is leading. So after some back and forth, we (Brecht,
Julian, Mike and I) seemed to have reached an agreement on the final
design (or rather, the principles behind the design) - guys correct me
if I'm wrong.

The idea is to leave which objects to show, and overrides handling
outside the viewport. This will be handled by the layer manager
project.

Options such as having the main object fully shaded with the rest of
the scene with clay render will be provided as built-in shading
options. Not configurable per "layer".

A visual draft of the UI is here [**]:

As always, let us know any thoughts you may have on any of this.

For anyone interested on the thought process, this is an early design
I presented today, on top of which we discussed.
