* lisp/org-macs.el (org-string-width): Do not handle dedicated
selected window specially. The bug fixed by 946abeb49
is no
longer reproducible using the release version of Emacs 29 and other
Emacs versions. Apparently, it was caused by now-fixed Emacs bug
specific to Emacs 29.
Also, use `buffer-text-pixel-size' as in `string-pixel-width' from
Emacs master. Using `window-text-pixel-size' requires setting buffer
to window, which is tricky when selected window is dedicated (see
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=64986).

(warn "Org version mismatch. Org loading aborted.
|
||
This warning usually appears when a built-in Org version is loaded
|
||
prior to the more recent Org version.
|
||
|
||
Version mismatch is commonly encountered in the following situations:
|
||
|
||
1. Emacs is loaded using literate Org config and more recent Org
|
||
version is loaded inside the file loaded by `org-babel-load-file'.
|
||
`org-babel-load-file' triggers the built-in Org version clashing
|
||
the newer Org version attempt to be loaded later.
|
||
|
||
It is recommended to move the Org loading code before the
|
||
`org-babel-load-file' call.
|
||
|
||
2. New Org version is loaded manually by setting `load-path', but some
|
||
other package depending on Org is loaded before the `load-path' is
|
||
configured.
|
||
This \"other package\" is triggering built-in Org version, again
|
||
causing the version mismatch.
|
||
|
||
It is recommended to set `load-path' as early in the config as
|
||
possible.
|
||
|
||
3. New Org version is loaded using straight.el package manager and
|
||
other package depending on Org is loaded before straight triggers
|
||
loading of the newer Org version.
|
||
|
||
It is recommended to put
|
||
|
||
%s
|
||
|
||
early in the config. Ideally, right after the straight.el
|
||
bootstrap. Moving `use-package' :straight declaration may not be
|
||
sufficient if the corresponding `use-package' statement is
|
||
deferring the loading."
