I've been meaning to make the progress bar synchronise with the beat
rather than a continuous countdown, just to give the overlay a bit more
of a rhythmic feel.
Not completely happy with how this feels but I think it's a start?
I had to refactor how the break overlay works in the process. It no
longer creates transforms for all breaks ahead-of-time, which could be
argued as a better way of doing things. It's more dynamically able to
handle breaks now (maybe useful for the future, who knows).
I didn't really want to move the cursor in front of the HUD, but we face
a bit of an impossible scenario otherwise (it should definitely be in
front of the break overlay for visibility).
So I'll deal with it for now.
People were deleting files they shouldn't, causing osu! to lose track of
where the real user files are.
For now let's just keep things simple and not let the users know that
some files got left behind. Usually the files which are left behind are
minimal and it should be fine to leave this up to the user.
