Bit unfortunate that this is code that can be written and do stupid
things. Unsure if additional API protections against this are desired
framework-side.
I need the actual overlay to be doing way more things (receiving the
actual websocket events, queueing the medals for display, handling
activation mode), so the pre-existing API design of the overlay just
will not fly.
Until now, many online textures were retrieved via the default texture store, which causes them to never be removed from GPU memory. It also has a performance overhead due to mipmap generation (which will be avoided via ppy/osu-framework#1885.
