Presumably the point where the hairs cross would follow the mouse.Yes, that's correct; like a draftsman's crosshair.
I'm not sure if there's a size limit on mouse cursors, but if not,
just making a crosshairs cursor more than twice the height/width of your
screen should do the job.
If I understand you, yes, that should work. But how is that done? I tried changing Xcursor.size in .Xresources but it didn't take?
