I noticed that the interpretation of the hpos given to the :align-to
space specification property changed in Emacs 29.1 compared to 28.2,
without it being documented anywhere. In version 28 it counts relative
to the visual start of the line, whereas in version 29 it starts at the
logical start of the line.

That is, the following MWE exhibits different visual behavior in Emacs
28 contra 29:

    (insert
     (concat
      "\n"
      (make-string (round (* 1.25 (window-text-width))) ?x)
      (propertize " " 'display `(space :align-to ,(round (window-text-width) 2)))
      "foo\n\n"))

(In 28 the text "foo" is centered correctly by the space. In 29 the
space has zero-width and no effect.)

The previous behavior makes more sense in the context of section 41.16.3
Pixel Specification for Spaces in the Emacs manual, and it would be
quite the breaking change so I am hoping it was unintentional.


Kind regards
Axel Forsman
