no double-caching of the pixmap (QPixmap::load() inserts into
QPixmapCache) and one less global static factory for plugins, no
functional change

now QSettings will behave much like opening a file via open() and the like,
see the QFile hijack test case

the code for translating strings in kdelibs (see
kdelibs/kdecore/localization/kcatalog.cpp) has finally made me roll my

this opens up possibilities for writing a new designer tool or
unexporting the designer and designer components classes and making

the whole change is optimization around reference counting (QString,
QImage, etc. are already reference counted), beware QVariant::data()

only Debian seems to enable the dispatcher and it does not
make much difference, probably because it ships 0.8.0 while
the latest (and bundled) 0.8.1 claim to provide +40% better
performance.
