	* libgimpwidgets/gimpdialog.c: implement GtkWidget::hide() and set
	the the focus widget to NULL, so a focussed entry emits focus_out
	and its callbacks are invoked immediately (before the call to
	gtk_widget_hide() returns). Fixes crashes and warnings in tool
	dialogs when hitting escape while a spinbutton is being edited.

	* app/tools/gimptransformtool.c
	(gimp_transform_tool_force_expose_preview): return silently
	instead of warning when being called while the draw tool is not
	active (same scenario as above).
