Oh btw, no matter what I have to pass the target dpi into the renderer to make sure the scale factor does not change, for printouts you want the image and symbols to be larger but the scale must be the same as on the screen, otherwise you end up seeing different symbology if you have scale dependent rules. So it's a matter of deciding wheter a second parameter is needed or not. WMS wise I'd say not, it would get quite confusing, so if I can't call it DPI I guess I'll have to compute the renderer DPI internally based on the OGC default DPI and the correction factor.
