The ::insert-pixbuf signal is emitted to insert a #GdkPixbuf
in a #GtkTextBuffer. Insertion actually occurs in the default handler.
Note that if your handler runs before the default handler it must not
invalidate the @location iter (or has to revalidate it).
The default signal handler revalidates it to be placed after the
inserted @pixbuf.
