Don't leave the user without progress bar just because the display's

2007-05-28  Michael Natterer  <mitch@gimp.org>

	Don't leave the user without progress bar just because the
	display's statusbar is invisible:

	* app/display/gimpstatusbar.[ch]: if the statusbar is invisible
	when a progress wants to be shown, temporarily show it, recording
	the fact in the new boolean "progress_shown" member. Added new API
	gimp_statusbar_get/set_visible() which is aware of the new
	temporary visibility state.

	* app/display/gimpdisplayshell-appearance.c
	(gimp_display_shell_set_show_statusbar)
	* app/display/gimpdisplayshell-progress.c
	(gimp_display_shell_progress_message): use the new API instead of
	showing/hiding the widget directly.
