Yesterday casper said something on IRC, he said that you can't put document-DPI zoom in the zoom manager. I thought a little about it and it struck me that we've been attacking this rasterizing of flake-shapes from the wrong angle.

The viewConverter for this special case is to convert from flake-internal to krita-internal. Meaning that (user)zoom-level is irrelevant. Only the image-wide DPI is relevant.

After that it was a simple task of writing a new implementation of the KoViewConverter interface based on that, and we're set.
