We don't provide any non-dialog way of selecting fonts because no one
has written code to do that.  The dialog we show uses OS APIs, and the
implementation, beyond popping up the dialog and using the value it
returns, is not in Emacs.

So we simply cannot offer the users control of this, since we don't
have code to find the available fonts relevant to Emacs and display
them grouped by family, typeface, size, etc., in a useful way.  We use
the system-provided dialogs instead.

IOW, this is not a bug.
