I'm really tempted to commit my broken qpainter canvas code. It offers lots=
 of=20
possibilities for optimization and it is a lot clearer and understandable,=
=20
but there are a few problems still -- that I have a hard time fixing:

* when zooming > 100%, the canvas is larger than the zoomed image. No idea=
=20
why, but it's probably one of those things I just cannot see because I've=20
spent too much time looking at the code.
* optimizations in the resizing and offset moving code are commented out. T=
hey=20
need to be fixed -- it's the case where part of the cached qimage can be=20
re-used and only the other parts need to rescaled and painted in

There are also a few things not done:

* qpixmap mode for those without xrender
* the nearest-neighbour-without-cache-as-big-as-the-kisimage mode

And probably a few others. But I need help here, and I guess the best way t=
o=20
get help is to commit.

Objections? As a carrot, I might add that as soon as I commit I can once mo=
re=20
hook up the gui to the layer system so we can add and remove layers once=20
again...
