Draw visualizer should have a search textbox

[Noordles]

Currently it's difficult and unintuitive to look for drawables in large containers (e.g. the ruleset's playfield).
Having a text box where you can filter out the name of the drawables would allow developers a quicker way to find a drawable.

You're welcome to give it a try yourself, you can look at SearchContainer for a quick start. Don't hesitate to reach out on discord if you face any problems along the way.

Note that this might not be as simple as just hooking up search container like that. Search in a tree view is a bit more complicated than in a flat list. You'll want to figure out what to do with a node that matches the filter, but none of its parents do.

There's an example of how this can be done in the settings implementation osu!-side. Though whether it will scale in performance is to be seen.

I've wanted a search box for draw vis for a while now, think this thought at least once a week.

I've been working on this for a bit but I've come across the question of what's the expectation when an item is filtered out. My question is: should the item disappear completely or should it hide the name?

E.g.

Disappear	Hidden
osu.Framework.Tests_tlkwJsp49j.mp4	osu.Framework.Tests_kw5C0ZqzmA.mp4

I would definitely prefer hiding filtered items completely from the hierarchy, rather than just fading them away in place, which feels more as if it's bugged.
