Visibility seems more buggy than intended

The engine seems to occasionally show and hide items that are still partially in view, which I assume is an intended retro effect of imperfect occlusion like many old games had it.

However, in some cases, this seems to go wrong to perhaps an unintended extent, when e.g. an entire house disappears that I am still inside of, or sometimes the entire map itself:

Perhaps this would be worth fixing? It can get a little in the way of looking around and exploring when suddenly the entire environment disappears. I'm guessing one way to fix it was to simply never hide something where some approximation of the box volume contains the player shape mostly or fully.

(The footage was captured on a Raspberry Pi 5, by the way. Amazing how well this runs even while screen capture is active, on such a limited device.)

That is a bug in the frustum culling code.

I did add a separate check to see if the camera is inside a model's AABB box to then skip culling, but that check is also bugged.

I'll fix it eventually.
