re-enabled the cache as designed.

for that, pixcache has now a method setting the size of cache (parameter count
of pix) and it will switched between the different views.
setPixmap is overloaded that way, that we don't store the pix inside the
item but calling calcRect which is accessing the cached pixmap. voila.
Zecke: Should we make a configure item where users can setup how much
pix-previews should cache? Should we setup a thumbnail cache like .xvpics?
