Remove unnecessary variable in Outline
Half-working adjustable outline font size

Font size and item height are adjusted fine, but all items initially appear as top-level ones (i.e. class members don't appear as such), and some items are displayed incorrectly (e.g. just the class name appears, but no members; moving input cursor into a member in the code inserts that member into the outline; moving to a different one replaces the just inserted previous item; etc.).
