Review request for kdelibs.


Summary
-------

This is used by KSysGuard to plot network usage etc.  I want to make it available for \
other people to use.

It is really quite feature-full, and uses a sliding window technique to minimize CPU \
usage for drawing.  On my system (dual core 3Ghz), drawing three of these graphs \
updating every 0.5 seconds takes about 1% of the CPU usage.


Diffs
