Once you've increased the width of these interword spaces to
their maximum, all the characters (and these increased spaces)
should be justified using interletter spacing, and this extra
interletter spacing should be applied as well between the dots
of the ellipsis (showing that they are effectively 3 separate
characters and not just one with a fixed distance between dots).
You are right that tracking and glyph scaling exist,
This is not glyph scaling
Because it's called tracking.
if the dots are circular, they remain circular.
When /glyph scaling/ is performed, it's by up to 2% (recommends
Bringhurst). That'll make circles ovals (different meaning of
"ellipsis"). And noone's gonna notice.
you may argue that the problem is similiar with the dots or diaresis
or Hebrew and arabic points, but these dots are less essential for
correct understanding of text on low resolution medias, or prints on
basic paper quality and with low cost inks.
Well, I'm not sure about Arabic i‘jām not being so important for visual
letter discrimination :-)
Btw, different aspect of the topic: math and Chinese are different; for
those separate ellipsis glyphs make sense.
