The g_print documentation explicitly says not to do this, since
g_print is meant to be redirected by applications. Instead use
g_message for logging that can be triggered via GTK_DEBUG.
gdk_x11_display_set_window_scale() affects the interpretation of the
Xft/DPI XSETTING - it is substituted inside GDK with the value of
Gdk/UnscaledDPI xsetting. However, this change is not propagated to
GTK+ and from GTK+ back to gdk_screen_set_resolution() until the
main loop is run.
Fix this by handling the screen resolution directly in gdk/x11.
This requires duplication of code between GDK and GTK+ since we still
have to handle DPI in GTK+ in the case that GdkSettings:gtk-xft-dpi
is set by the application.

We have a hack in the XSETTINGS code to substitute gtk-xft-dpi
with gdk-unscaled-dpi unless the screen has a fixed window scale,
in which case we just use gtk-xft-dpi.
But if the screen is changed to have a fixed window scale, then
the substituted value of gdk-unscaled-dpi will stick around until
the next (coincidental) change to XSETTINGS. To fix this, force
an immediate reread of the XSETTINGS property when
gdk_x11_display_set_window_scale() is used.

This lets use use a scaled Xft/DPI for old apps while not
blowing up the size of scaled windows. Only apps supporting
Gdk/WindowScaleFactor should supprt Gdk/UnscaledDPI.

* gdk/x11/xsettings-client.[hc]: Change the XSettingsWatchFunc
to return a Bool to indicate success. Update callers and
implementors. Based on a patch by Owen Taylor.
* gdk/x11/gdkevents-x11.c (gdk_xsettings_watch_cb): Don't
leak a reference to gdkwin.

Try to fix#315732, reported by Luke Hutchinson:
* gdk/x11/xsettings-client.[hc]:
* gdk/x11/gdkdevents-x11.c: Don't assume that ref'ing a GdkWindow
will guarantee that it can be looked up in the xid hash later.
Also, use the nesting server grab function during the xsettings
client initialization. Finally, make xsettings client not
eat DestroyNotifys so that GDK can do its regular cleanup.

Make GDK+ compile with X11R5 (#148032)
* gdk/x11/xsettings-client.c (xsettings_client_new):
* gdk/x11/gdkproperty-x11.c (_gdk_x11_precache_atoms): Only
use XInternAtoms if it is available.
* gdk/x11/gdkasync.c: Include XIproto.h if necessary.
* configure.in: Check for XInternAtoms and X headers needed for
xReply.
