More compact selection panel when multiple items selected

• Closes Multi-selection selection panel reborn #8336

What

When you have more than one item selected at once, you get a list of all items. Clicking one will select just that.

Implementation

A bit messy, to be honest. I leveraged the existing ItemTitle for some items, and hand-rolled others.

It would be nice with something similar to DataUi, but for titles (with or without breadcrumbs).

But the amount of messy code is low and low-impact, so unless someone has a good suggestion or strongly objects, I suggestion calling this "good enough for now".

I like it otherwise but this is quite the step backwards for interacting with objects in 2d views with images :/

I believe you are referring to the problem outlined in this issue:

• Can't select/click a 2D primitive without also selecting underlying image #6761

Clicking e.g. a point in a 2D view would also select all images below the point:

With this PR, the same click now produces this selection panel:

The old behavior was already really bad, imho. Why would clicking a point select the image behind the point? That's just a bug imho.

Clicking two translucent images is arguably different. But is it really better to get a list of expanded items, forcing you to scroll, or to show a concise list of things under the mouse, prompting you to refine the selection with a second click?

Is it though? Sure you need one more click to inspect that point/box2d thing. But the entire process makes so much more sense now. Click places -> stuff there is shown to me -> can make educated choice on what really is of interest.

That being said, images are generally very easy to select by themselves, so I wouldn't be against filtering them out of any picking multi-selection.

Very nice!
