Sets the size of the column in pixels. This is meaningful only if the sizing
type is GTK_TREE_VIEW_COLUMN_FIXED. The size of the column is clamped to
the min/max width for the column. Please note that the min/max width of the
column doesn't actually affect the "fixed_width" property of the widget, just
the actual size when displayed.
