◆ modify_filter_gaussian_blur_from_item()

SPFilter * modify_filter_gaussian_blur_from_item	(	SPDocument *	document,
		SPItem *	item,
		gdouble	radius
	)

Modifies the gaussian blur applied to the item.

If no filters are applied to given item, creates a new blur filter. If a filter is applied and it contains a blur, modify that blur. If the filter doesn't contain blur, a blur is added to the filter. Should there be more references to modified filter, that filter is duplicated, so that other elements referring that filter are not modified.
