Hello and thanks for the "resolution divider in blender internal" (Differentail #D609)... works great!

However, if you also turn on "Freestyle' render option and then turn on "rendered" preview in View3d, the freestyle renderer is called once for each lower resolution, which make preview unreasonably slow.

It is easy to reproduce with factory settings like this:

start new factory startup file
enable "Freestyle" button
enable "Viewport Shading | Rendered"
remove the default cube
add a Suzanne.
add a 3x subdivision surface modifier
(try) to navigate in Viewport

It does work as "expected" but what it does is call freestyle renderer over and over.

For just the default cube freestyle is quick enough but complex scenes causes a
noticeable delay in navigating as the freestyle renderer is called multiple times.

I suggest that Freestyle is only called once after the highest resolution is complete.

I was going to report this as a bug but didn't know what was causing it! but I can confirm the behavior - each 'blink' and redraw is quite slow for many edge scenes, making the viewport preview a real bottleneck.
