I don't agree - it is going to break many applications doing graphics and 
PDF export for a micro modification that isn't much better than the 
existing API. Is this really worth the incompatibility ?

Please have in mind that for Qwt I will have the problem that all pens 
are created in application code, while the painter ( and its render hints 
) is usually created inside of the Qwt library. An exception are f.e. 
report generators: here the exported plot is part of a document and the 
application creates the painter passing it together with a target 
rectangle to Qwt.

I have no idea how to hide the incompatibility inside of the Qwt library. 
I'm afraid in the end it will be something every Qwt application has to 
handle manually.
