removed gimp_enum_combo_box_set_visible(). 

2005-03-01  Sven Neumann  <sven@gimp.org>

	* libgimpwidgets/gimpenumcombobox.[ch]: removed
	gimp_enum_combo_box_set_visible().

	* libgimpwidgets/gimpintcombobox.[ch]: added
	gimp_int_combo_box_set_sensitivity() instead.

	* app/tools/gimpcurvestool.c
	* app/tools/gimplevelstool.c
	* app/widgets/gimphistogrameditor.c: changed accordingly.

	* libgimpwidgets/gimpenumstore.h: added padding for future expansion.

	* libgimpwidgets/gimpwidgets.def: updated.
