alignment/margin vfuncs adjust_size_request/allocation Now get_height_for_width() will internally update the for_width before passing it to the real height_for_width() vfunc, allowing margins and extra space for alignments to be stripped, thus requesting sufficient height for greater than natural widths (and also accounting for margins properly). Test case adjusted in testadjustsize to ensure proper behavior.
