Review request for kdelibs.


Changes
-------

And one more: my comment on the loading by xdg-icon name was nonesense. It is \
perfectly possible and makes for very nice code. This patch introduces that.


Summary
-------

Showing a spinner to indicate a work in progrss is a typical task. Gwenview does have \
a nice spinner when loading images. Aurelien and I extracted the code from Gwenview \
and molded it into three nice classes that allow to create spinners very easily in \
any situation. At the moment the classes are used in Gwenview and in Nepomuk.

KPixmapSequence: a simple container class that loads a sequence of pixmaps and \
                provides the frames through a simple interface.
KPixmapSequenceOverlayPainter: Installs an event filter to paint a KPixmapSequence \
                onto any widget using Qt::Alignment or a relative placement.
KPixmapSequenceWidget: A simple widget using the overlay painter to draw a spinner \
while the widget is visible.

We propose an addition to kdeui.
