Painter: transform coordinates but not pen width settings

[tzioboro]

Hi I had the same problem ...
Anybody that get here - you might use QPen::setCosmetic - that will obey all transformations and draw line with given width of pixels.
If you are going to use it with different devices (ex. printer and screen) you might recalculate thickness regardles to device ppi or other metrics.

This thread was very helpfull about this:

QPen::setCosmetic(true) works fine on all platforms except Mac. There are some issues on Mac and even after making the pen cosmetic, it's getting scaled. Check out this bug log too:
