- Important note: If you prescale the textures anyway, you might want to
- waste some time on doing it the matemathically correct way.
- Instead of simply adding 4 pixels with equal weigths, you should add *9*
- pixels like this:
- 1/16 1/8 1/16
- 1/4 1/4
- 1/8 1/4 1/8 instead of simply
- 1/4 1/4
- 1/16 1/8 1/16
-
- This corresponds to performing a 'gaussian blur' and then doing a raw
- scale. It looks *MUCH* better.
