Thanks.

Please avoid using "when" as a conditional; use "if" instead.  "When"
can be interpreted as time-related condition, which is not what you
want.

This uses double negation, which makes the documentation harder to
understand.  Suggest to rephrase:

  By default, clone the pixel-size of the original frame, but if
  `frame-resize-pixelwise' is nil or FRAME is a text-only frame, use
  the FRAME's number of lines and columns for the clone.

Why do you need this condition?
