#16 : I'm agree with Marcel. We must take a care to not make a bad impression
about thumbs.

#14 : agree with Mik, but speed-up improvements can be see on Single CPU
computer. On Double core, nothing (tested on 8 differents computers)

What do you think about this way :

1/ Always compute cache with SmoothScale to 256x256.
2/ In second pass,

- If size is 256, do nothing.
- If 256 > size >= 128 : use cheatscale
- If size < 128 : use FastScale (we cannot see details indeep here).

Or perhaps alwyas use cheatscale if size < 256. In all case, no need to to
touch thumb if size = 256.
