Re: [csswg-drafts] [css-fonts] Proposal to extend CSS font-optical-sizing (#4430)

There is opsz, but as we know now it is some value translated into some pixels translated in some size by environments, and not necessarily resulting in type where the input in points represents the output in typographic points.

We should then resurrect POPS, FBs proposed optical size axis that is valued only in typographic points, as determined by standard measure of 72 to the inch, or equivalent devices whose ppi can be measured in actual pixels per inch/72.

And PPMS could stand for an axis that represents pixels per em, which would be useful for variations based on pixels as the target for both typographic glyphs, (the more complex the glyph(s), the more useful such an axis would be), and also for emoji and other small graphics, where pixels are important, and either resolution is not, and/or hinting in not available. Such an axis could require separate x and y values, though today, its target would be primarily be a square grid.

How about a new opsx axis that is specified to pixels not points?
