The cairo driver plots look the same across different types of  
output. I don't think this will be easy to change since this  
consistency is one of the goals of the cairo project.

I'm pretty sure that none of the drivers I've nominally been  
responsible for (aqt, svg and cairo) implement text clipping. I'll  
see what I can do...

The driver itself ignores both flags.

Should I continue to address these issues rather than the next release?
