stuckness :-(

[Boudewijn Rempt]

I've been busy before I lost my last laptop and after I got my new one working 
on the qpainter canvas. This canvas is pretty essential, since it's the 
default and there's a lot of variation in what different systems support. 
I've made it extremely configurable:

* it can either get the image pixels from KisImage using nearest neighbour, or 
cache the KisImage projection as a QImage (with a size limit)
* it can smootscale using blitz or qt for scale < 1.0
* it can optionally smooth using Casper's fixed routine between 1.0 and 2.0
* it can create a qpixmap or a qimage (at least, htere's api for that, but no 
implementation yet)
* and there are more settings and options to make sure it works on 32 and 64 
bit systems, xrender and no xrender

But I'm stuck; even with the "normal" path (caching, blitz < 1.0, sample 
1.0-2.0, qpainter scaling > 2.0), I get artefacts and the canvas thinks the 
image is bigger than it really is.

I don't want to commit, since it breaks Krita horribly, but I would appreciate 
any help! So here's the patch, if the mailing list lets it through...
