gtk-text-tag-changed (tag changed)

tag -- a gtk-text-tag object
changed -- a boolean whether the change affects the gtk-text-view layout

Emits the "tag-changed" signal on the gtk-text-tag-table object where the tag is included.

The signal is already emitted when setting a gtk-text-tag property. This function is useful for a gtk-text-tag subclass.
