Docs incorrectly say to include gtkunixprint.h
Lots of API ref pages in both gtk3 and gtk4 incorrectly list the Includes as:
#include <gtk/gtkunixprint.h>
See this one, for example: https://developer.gnome.org/gtk3/stable/GtkLockButton.html
I think it's because of how they're listed in docs/reference/gtk/gtk4-sections.txt
. It looks like new classes just got appended, but that puts them under this line:
<INCLUDE>gtk/gtkunixprint.h</INCLUDE>
They should probably be moved up above line 5575.
