	* app/display/Makefile.am
	* app/display/gimpdisplayshell-appearance.[ch]: new files
	implementing canvas padding, fullscreen toggling and utility
	functions to show/hide GimpDisplayShell components (menubar,
	statusbar, ...) Added the possibility to show/hide the scrollbars.

	* app/display/gimpdisplayshell.[ch]: added struct
	GimpDisplayShellVisibility which stores the GUI components'
	visibility. Added two such structs to the GimpDisplayShell struct:
	one for normal mode and one for fullscreen mode. Default to
	"everything invisible" for fullscreen.  Fixes bug #74383.

	* app/display/gimpdisplayshell-callbacks.c: fiddle with the
	two visibility structs when toggling fullscreen.

	* app/display/gimpdisplayshell-handlers.c: #include
	"gimpdisplayshell-appearance.h"

	* app/gui/image-menu.c
	* app/gui/view-commands.[ch]: added a "Show Scrollbars" menu entry,
	use the new widget show/hide utility functions.
