Now it seems method 2 that is the fastest by now makes some troubles on patterns like eg brick walls. since it does not scale the image, but uses every Nth pixel, moire interference patterns appear on the gloom texture. A bit like silk in TV. (smoothing cannot fix this)
Unfortunately this wasn't obvious in the test app.
So I need a better way to scale. Message to myself: gotta buy a cell phone, so people don't think I'm a freak when I'm talking to myself :)
