For example, QPixmap does not allow direct manipulations with its pixel buffer which might be used to speed up some operations. I'm just wondering if such trick was an initial motivation for QPixmap -> QImage conversion.

QPixmap::toImage and fromImage allow you to do almost everything you could do with a QImage directly. QPixmap stores an implicitely shared copy of the QImage internally.
