Hrm, -dirty seems to have a heavy influence on bounces :o.
I tweaked the -bouncescale with a -dirty compile,
thus the non-dirty compiles are overblown a bit – probably raising the number
of bounces quite a lot. I will try to get a nice -bouncescale
value for non-dirty compiles when I find time.

Difference between the two –-dirty– images
Ignore the white lines at the edges of polygons, they're caused by the merge of non-pixel-perfect images. The noise is caused by JPEG artifacts in both the source and these images.
