[meta] Issues of binary recordings

[kvark]

Problems I encountered:

1. Wrench player has to be built from exactly the same WR revision as the recorder, otherwise bad things happen
2. When replaying, all of the keyboard input, title frame number, and actually displayed frame - appear to update at different moments (de-synchronized). It's difficult to fast-forward in a predictable manner.
3. Saving frames when running with --play doesn't get some of the last frames saved.
4. Showing individually saved frames doesn't always get the same rendering as the binary replay.

@kvark Do we need to keep this open? Should we just remove the old binary recording code completely now?

I wouldn't rush with removing it yet. The new capturing is not continuous, let's give it some time to mature before considering to remove the recording. I'd keep this open for as long as it's either fixed, or the whole thing is removed :)
