A bug existed before where certain events would not update Engine's lastTick. If the sim was lagging hard, then this could cause "script is not responding" errors to appear in unintentional situations.
The starting execution time is tracked in LuaScriptInterface instead now, and set in tpt_lua_pcall
Request ownership is no longer flaky. Requests are now owned by the code that makes requests, and Requests and the RequestManager co-own RequestHandles. RequestManager disowns a RequestHandle if it's done with it or if Request code reports that it's no longer needed.
All libcurl code has been moved to RequestManager. This is nice because once NOHTTP is removed, we can add any number of RequestManager implementations, for example one for Android.
Client outliving RequestManager is still a problem, this will have to be addressed later.
It wouldn't actually open them, it'd just exit back to the currently open save. It's better to tell the user the reason why the save is broken instead.
I've seen the nullptr deref, but I don't see how it's possible at all. A condition for file->LazyUnload to be called is for SaveButton::wantsDraw to be false, but for that to happen, SaveButton::Tick has to be called after a call to SaveButton::Draw to reset it to false, and then *again* for it to see it being false on entry.
Whatever, the bug is genuinely there and is bad, and easy to fix, no need to figure out in what way it is bad exactly.
So instead of loading every save in sight and rendering the thumbnails for them too, SaveButtons will only do this when they are actually visible, and unload saves and thumbnails when they are not.
Also remove the "Rendering thumbnails" progress bar, which did absolutely nothing.
Also restore concurrent connection / stream counts, and fix a bug that would cause AvatarButtons to try to fetch avatars before they knew what name they belonged to. I apparently broke this in the first PNG commit.
Also write PNGs with libpng, and BMPs with SDL, and have the renderer only generate a large PNG thumbnail, and disable HTTP/2 multiplexing for now so we don't get banned when loading avatars.
simon pls reply to the stupid emails already.
