      Can anyone tell me why Metal’s generateMipmapsForTexture function seems to output 8bit levels from a 16bit float texture? Bug? User error?

      This is a Bad Thing when the texture contains negative values :D But it must be common for e.g. normal maps.

      Answering my own question: Strange things happen when generating mipmaps with odd-sized 16bit textures. Radar time.
