I have no idea why the PLplot core drawing clipping is acting in that peculiar way (visible offsets to clipping at the left and right borders of the overall X window) for -ori 0.5. Even if you try ./x01 -dev xwin -ori 0.5 -a 1 -geometry 800x800 there is a small (but incorrect, IMO) visible clipping offset at the right and left borders. And I wouldn't be surprised if there is also a similar incorrect clipping offset at the top and bottom as well which goes the other way so you don't see it because it is completely outside the X window. So I think your current cairo text clipping is correct, and the core drawing clipping wrong for non-integer -ori values. I guess we can ascribe this to yet another strange core effect for non-integer -ori values. Anyhow, the core and xcairo now agree about clipping for integer ori values which is the important thing.
