Thanks!
Several nitpicks:

https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-29&id=86f2d6d62fce90d19815503e3e99ac9c4d4585af
+    . decide which windows on which frames need their windows
                   ^buffers?
+      considered for redisplay

+   For buffer parts that have been changed since the last redisplay,
+   `redisplay_window' __constructs__ a second glyph matrix ___is constructed___,

+   part of the display by scrolling lines.  The actual update of the
+   display of each window ___by comparing the desired and the current
+   matrix___ is done by `update_window', which calls functions which draw

maybe put that clause after by `update_window'.

+   to the glass (those functions are specific to the type of the
+   window's frame: X, w32, NS, etc.).
