Review request for kdelibs.


Changes
-------

* ran astyle to fix all remaining code style issues
* check for invalid sequences in KPixmapSequenceWidget::setSequence
* do not return valid frames for index bigger than the frame count.
* implemented loading of multi-row pixmaps. Would it be preferable to have a method \
setFrameSize and do lazy extracting of the frames as done in KAnimatedButton?


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.
