With this simple patch loading of thumbnails is much, much faster. Of course it
comes with price - slightly lower quality of thumbs (but only on display,
generated thumbnails are of good quality).

It is done by simple change from SmoothTranformation to FastTransformation.

I understand that this trade off isn't good for everyone but digiKam experience
becomes much smoother after removing of Smooth transformation ;)

Several possible solutions:
- use that patch as is and accept slightly lower quality (really visible only
with smallest thumbnails of 80px - and really, who could expect super quality
from those thumbs ;)
- make option in config dialog a) lower quality of thumbs, faster loading b)
high quality of thumbs, slower browsing of albums
- load thumbnails in two passes: first time with FastTransformation, second,
after eg. 2-3 seconds of inactivity with Smooth transformation
