debug visualisation for BSP areas #46
Description
Apparently entities inside a misc_bsp only render properly in certain locations in the void on certain maps. Supposedly, this is connected to the area (as used by area portals), only "broadcast" entities are drawn regardless of the current area.
Ideally, the areas of the misc_bsp should be used to decide whether to render its entities, i.e. we should fix the root cause.
However, for backwards compatibility with vanilla, we should also make it easier to find these "safe" areas to build in the void. Visualising the area check algorithm would help.
