Rather use a proper alpha channel if we need transparency. This is another small step towards merged alpha in our vcl layer. I suspect the intent in a lot of this code was to save memory. Which have been a thing way back then, but these days our backends mostly end up doing a copy-and-convert to a real alpha channel anyway, so the existing code is actually now a pessimisation.
