Returns the text in the range [@start,@end). Excludes undisplayed
text (text marked with tags that set the invisibility attribute) if
@include_hidden_chars is %FALSE. Does not include characters
representing embedded images, so byte and character indexes into
the returned string do not correspond to byte
and character indexes into the buffer. Contrast with
gtk_text_buffer_get_slice().
