- adjust semantics of gnumeric_run_dialog to set the parent.

2000-01-26  Jody Goldberg <jgoldberg@home.com>

	* src/gnumeric-util.c (gnumeric_dialog_run) : Handle the setting of
	  the parent here rather than scattering it throughout the system.

	* src/item-grid.c (item_grid_event) : Support mouse-wheel scrolling.
