So, according to what I can read of the X protocol specification,
neither the vesa nor intel drivers have a bug here. They are allowed
to differ in these details of which pixels get lit. (And if anything,
vesa is the odd one for not matching the algorithm of line_width=1.)

So, to fix the bug, wine is going to have to change its code to not
rely on the pixelization of zero-width lines, (which can differ from
one driver to the next), and should instead use lines with
width=1. Making this change will require making some adjustments to
how the segment endpoint coordinates are computed to still achieve the
desired result.
