In theory this seemed like a good idea (and an optimisation in some cases, due to lower fill rate), but in practice this leads to weird edge cases. This aims to do away with the operations on external drawables by applying a dim to the area behind the `LoadingLayer` when required. I went over each usage and ensured they look as good or better than previously. The specific bad usage here was the restoration of the colour on dispose (if the `LoadingLayer` was disposed in a still-visible state). I'm aware that the `BeatmapListingOverlay` will now dim completely during load. I think this is fine for the time being.
