[css-shapes-2] `curve to` keyword `using` seems a bit off

[fantasai]

We adopted #9797 which allowed reordering and switched via to using but we typically use prepositions, not verbs, for these types of keywords and also using is a bit vague in any case. Opening this issue to look for alternatives.

My opening bid is around. :)

per, with

See #10644 (comment)
Perhaps we can avoid this keyword at all and use ordering, this would also allow us to specify positions for curve control points without breaking relative positions.

[fantasai]

towards?

[noamr]

towards?

per / with are more accurate for describing "control points"... though as (per) my previous comment we might be able to get rid of this keyword altogether.

@noamr Ordering alone with a long sequence of length values is hard to understand (this is one of the problems with the existing SVG paths syntax), so I think having a keyword here is helpful to signal the start of the control points.

Also the control points should have some kind of separator themselves, as a sequence of 4 values that are actually two pairs is confusing to parse (as a human).

Yea, using / as a separator in the example

[noamr]

@fantasai the thing with any of these words is that they collide with the by/to that represents absolute vs relative. So using order with a separator like / instead and still allowing by/to seemed the least verbose.

Seems like in the other discussion with kept being what both myself and @smfr defaulted to. Perhaps this is the right word?

Proposing the following to finish up the bezier curve saga:

• with is the word
• We use / to separate between the two control points in a cubic bezier, no need for it in quadratic/smooth curves.

@smfr @tabatkins @fantasai what say you?

Could you type out some examples of the various absolute/relative versions? I think this matches what I suggested at #10644 (comment)
