See the node "Low-Level Font" in the > ELisp manual, it describes this stuff. Could there be support functions (font-height-list :family family) and=20 (font-weight-list :family family) so they can be used with (buffer-face-mode-invoke=20 `(:family ,face-family :height ,face-height :weight ,face-weight) t) As the height and weight are customarily asked by users wanting to change font. If one can get the specific values available for a specific family, one would not run in the frequent difficulty of supplying non-existent values, resulting in no changes being applied.
