Almost forgot this. In case someone is interested in the solid fill
performance, I've uploaded a plot here:
http://www.math.uni-bielefeld.de/~tjakobi/exynos/g2d_clear_perf.pdf

And yes, that should be _nano_seconds on the y-axis. What I find
interesting that despite the performance being linear (well, affine
linear, since we have a setup time) in the number of pixels to process,
you can still see some kind of 'clustering'.
I wonder where this comes from, maybe some small alignment penalty, or
something?

With best wishes,
Tobias
