[comp.windows.x] X11 PolyLine

Can someone tell me why, "if wide lines intersect, the intersecting pixels are
drawn only once, as though the entire PolyLine were a single filled shape"?  In
this respect, PolyLine differs from all the other graphics requests.  I realize
that the specified effect is desirable, but this requirement associates a unique
performance burden with the old graphics workhorse. Why wouldn't it be better to
charge it to those few who truly need it?
