I just skimmed these articles. Looks like good stuff; but there are a few comments about how zooming in SP1 is broken (zooming happens after the controls are rendered from vector to bitmap instead of before)...

Greg explained that in his comment: http://blogs.msdn.com/greg_schechter/archive/2008/05/12/gpu-accelerated-custom-effects-for-wpf.aspx#8501940

"Note that the above is *only* about out-of-process magnification. When you do zooming (via scaling) within your own WPF application, the rendering continues to be re-rasterized at the higher scale, so everything remains smooth in that most common scenario. This change is strictly about using the external magnifier."
