Gets the current run. When iterating by run, at the end of each
line, there's a position with a %NULL run, so this function can return
%NULL. The %NULL run at the end of each line ensures that all lines have
at least one run, even lines consisting of only a newline.
Use the faster pango_layout_iter_get_run_readonly() if you do not plan
to modify the contents of the run (glyphs, glyph widths, etc.).
