If I had to guess, I'd say that what you're seeing is the performance of
width 1 lines.  The X protocol distinguishes width 0 lines (which can be
rendered in an arbitrary way) from width 1 lines (which must satisfy
certain mathematical properties).  The R4 server handles width 1 lines
by using the general wide-line code.  The XNews server treats width 1
specially.  Some suspicions were raised at the X conference that the
resulting lines don't meet the specification, but I don't know for sure.
