	* app/tools/gimpperspectivetool.c
	* app/tools/gimprotatetool.c
	* app/tools/gimpscaletool.c
	* app/tools/gimpsheartool.c: removed calls to
	gimp_transform_tool_expose_preview() from all
	GimpTransformTool::motion() implementations...

	* app/tools/gimptransformtool.c: ...and call it after calling
	tr_tool_class->preview().
