Observation of a zoom-engine of PS

[Dmitry Kazakov]

Hi!

Just an observation i got today while using PS7.  =)
It has quite good and fast zooming engine. And the most interesting fact
about that - it uses different zoom-algorithms for different zoom-levels.
More exactly:

For zoom-levels 100,50,25,12.5 - it uses smooth-scale algorithm
For other levels - nearest-neighbor. More than that, it uses nearest
prescaled(?) image for NN-sampling.
