	* libgimpwidgets/gimpunitmenu.[ch]:
	* libgimpwidgets/gimpwidgets.c: added an API to allow for
	sub-pixel sizes in spinbuttons connected to a GimpUnitMenu.
	Make GimpUnitMenu emit "unit-changed" when the unit is changed
	programmatically.

	* libgimpwidgets/gimpsizeentry.[ch}: added a similar API here.
	Make GimpSizeEntry emit "unit-changed" when the unit is changed
	programmatically. The other signals will need similar changes.

	* plug-ins/common/gauss_rle.c
	* plug-ins/common/gauss_iir.c
	* app/widgets/gimpstrokeeditor.c: use the new API.
