	* app/config/gimpconfig-utils.[ch]: removed
	gimp_config_values_equal().

	* app/config/gimpconfig-serialize.c
	* app/config/gimpconfig.c: use g_param_values_cmp() instead so
	our registered compare methods are used.

	* app/config/gimpdisplayconfig.[ch]: added "canvas_padding_mode"
	and "canvas_padding_color" properties.

	* app/display/display-enums.[ch]: added enum GimpDisplayPaddingMode
	which can be one of { theme, light check, dark check, custom }.

	* app/display/gimpdisplay.h
	* app/display/gimpdisplay-handlers.c: removed cached monitor
	resolution values...

	* app/display/gimpdisplayshell.[ch]: ...and added them here. Added
	padding state as in GimpDisplayConfig. Added utility function
	gimp_display_shell_set_padding() which hides all the details.
	Added the new padding modes to the padding color button's context
	menu.

	* app/display/gimpdisplayshell-callbacks.[ch]: don't fiddle
	with colors manually but use gimp_display_shell_set_padding()
	in realize() and in the color button callbacks.

	* app/display/gimpdisplayshell-handlers.c: connect to
	notify::monitor-[xy]resolution and
	notify::canvas-padding-[mode|color] and update accordingly.

	* app/widgets/gimppropwidgets.[ch]: added
	gimp_prop_color_button_new().

	* app/widgets/gimpdialogfactory.[ch]: added
	gimp_dialog_factories_session_clear() (unimplemented).

	* app/gui/preferences-dialog.c: added widgets for padding mode and
	color. Removed some callbacks by connecting the functions they
	called directly. Cleanup.
