Creates a new gtk.TextView widget displaying the buffer
buffer. One buffer can be shared among many widgets.
buffer may be NULL to create a default buffer, in which case
this function is equivalent to TextView.new. The
text view adds its own reference count to the buffer; it does not
take over an existing reference.
