* gdk/gdkdisplay.[ch] gdk/gdkscreen.[ch] gdkinternals.h:
Start implementing display/screen closing scheme; keep a
flag for whether displays and screens are closed,
call g_object_run_dispose(). Remove public gdk_screen_close().
* gdk/x11/gdkdisplay-x11.c gdk/x11/gdkscreen-x11.c: Add
dispose() methods; move appropriate parts of the finalize
there.
* gdk/x11/gdkcolor-x11.c gdk/x11/gdkimage-x11.c
gdk/x11/gdkmain-x11.c gdk/x11/gdkpango-x11.c
gdk/x11/gdkpixmap-x11.c gdk/x11/gdkproperty-x11.c
gdk/x11/gdkselection-x11.c gdk/x11/gdkwindow-x11.c:
Start of making everything correctly ignore operations
when a display has been closed.
* gdk/x11/gdkwindow-x11.c (gdk_window_get_decorations):
Handle decorations == NULL.
* gdk/x11/gdkcolor-x11.c (gdk_colormap_remove):
Remove unnecessary hash table creation.
* gdk/x11/gdkinput.c gdk/x11/gdkinput-x11.c gdk/win32/gdkinput.c
Fix up gdk_device_get_history - handle events, n_events == NULL,
etc.
* gdk/x11/gdkproperty-x11.c (gdk_property_get):
Handle failure better.
* gdk/x11/gdkselection-x11.c (gdk_selection_property_get):
Handle failure better, handle data == NULL, move docs
here, remove an excess round trip by asking for
all selection data at once.
* gdk/gdkselection.c gdk/win32/{x11,win32}/gdkselection-{x11,win32}.c
gdk/{x11,win32}/gdkmain-{x11,win32}.c gdk/gdkdisplay.c: Move
gdk_text_property_to_text_list(), gdk_string_to_compound_text(),
gdk_display_set_sm_client_id() to display-independent part of GDK.
* gdk/Makefile.am (gdk_c_sources): Sort gdkdisplay/screen.[ch]
into the right place.
