Trolltech did the separation in Qt4.  Their major libraries are 
libQtCore, libQtGui, libQtMultimedia.so, and libQtNetwork.so.  The other 
libraries essentially add on additional functionality.

The same sort of thing could be done with Qt3, but I question the value. 
  If someone is building a new application, they would probably just 
build it with Qt4.
