Until now we've played around with Core Image, Quartz and NSImage
but we're still unsure which approach is the most "efficient" one.
We want the screensaver to have the lowest possible CPU load, while
still offering smooth translations/transitions. Monitoring e.g.
"Beach" shows almost no CPU load... exactly what we want!
I'm pretty sure the built-in screensavers use OpenGL and simply shift
very simple textured rectangles about. The work is offloaded to the
GPU in this case which explains the low CPU load.
