This looks like a big step forward.  We need to figure out the right
interface for using the new method, though.

    (defun x-select-font-for-face (face frame)
     "Select the font to be used for FACE on FRAME.
    `x-select-font-command' will be used to make the selection."

That seems like a rather strange way to do things.

    (defun set-font-for-face-at-point ()
      "Set the font to use for the face currently under point."

That also seems strange.  When the user wants to specify a font for
the text, he would want it to work either directly (not using a
particular face) or by creating a new face, not by changing an old one.
