Text.get_window_extents returns pixels, which get_label_width converts
to points, only for all call sites to immediately convert back to
pixels. Just introduce a new internal API which uses pixels throughout.
(We could possibly deprecate get_label_width, but heh.)

Edit: get_label_width is deprecated, per the discussion below.

👍 I consider removing unneeded public API important. I reduces clutter for users as well as devs. And it makes maintenance and changes easier in the future.

Text.get_window_extents returns pixels, which get_label_width converts
to points, only for all call sites to immediately convert back to
pixels.  Just introduce a new internal API which uses pixels throughout,
and deprecate the old one.
