It would be possible, but I don't think it would look nicely. For instance,
EPS vector graphics
use floating point coordinates instead of the integer coordinates of
QPainter, so would be a loss
of quality. This applies especially for small images like thumbnails. You
can give small numbers like e.g. 0.002
for linewidth, and can make your Postscript interpreter use this
information. It is not possible with teh current
QPainter.
My idea would be a special Painter which uses a Postscript like rendering
model, but I am afraid there are some
opponents to this :)

I.e. VPainter (Karbons paint device) using libart for rendering on demand.
