	* app/display/gimpdisplay-foreach.[ch]: added new function
	gimp_displays_invalidate() which queues a redraw on all displays
	by calling gimp_display_shell_expose_full().

	* app/display/gimpdisplayshell-render.c (render_setup_notify):
	invalidate all displays when the transparency type or size changes.

	* app/tools/gimptexttool.c (text_tool_button_press): readded some
	code I accidentally removed in my last commit.

	* app/text/gimptextlayout.c (gimp_text_layout_new): always set the
	font size but make sure it is at least 1.
