XDRIVER passes the line width directly to XChangeGC. X specifies the
precise behaviour for non-zero line width, but drivers have some
freedom as to how zero-width lines are handled, so they can use the
hardware's "thin line" drawing primitive, if it has one. A width of
zero can potentially result in significantly faster operation.
