The part runs before write_glyphs does not need to change.
In the extreme case, it could be sufficient to just replace low-level
drawing API calls such as XFillRectangle with some other API calls to
add dirty rectangle. But this is so low-level and inefficient, and
more high-level drawing function can take care of the addition of the
dirty area in an earlier stage.
