jo,

just a note. Unfortunately crop & rotate module does not work with downsampling
set to less then 1.0. Because this is very important module I had to go
back to 1.0 and now I do again suffer from slow preview rendering.

It would be great if could be resolved early. I created the redmine issue
#9769 on this.

Thank you,

Suni
