Yes.

We currently have:

 - poppler_page_get_selected_text, that takes a rectangle
 - poppler_page_get_text, that doesn't take a rectangle

We have already broken the API with poppler_page_get_text so we can
just add a new parameter to specify the tetx order, or we can add
another method poppler_page_get_raw_text(). I prefer to add a new
method because poppler_page_get_text is used in combination to
poppler_page_get_text_layout()
