  @tindex display-grayscale-p
  This function returns @code{t} if the screen can display shades of gray.
  (All color displays can do this.)
+ @end defun
+ 
+ @anchor{Display Face Attribute Testing}
+ @defun display-supports-face-attributes-p attributes &optional display
+ @tindex display-supports-face-attributes-p
+ This function returns address@hidden if all the face attributes in
+ @var{attributes} are supported (@pxref{Face Attributes}).
+ 
+ The definition of `supported' is somewhat heuristic, but basically
+ means that a face containing all the attributes in @var{attributes},
+ when merged with the default face for display, can be represented in a
+ way that's
+ 
+ @enumerate
+ @item
+ different in appearance than the default face, and
+ 
+ @item
+ `close in spirit' to what the attributes specify, if not exact.
+ @end enumerate
+ 
+ Point (2) implies that a @code{:weight black} attribute will be
+ satisfied by any display that can display bold, as will
+ @code{:foreground "yellow"} as long as some yellowish color can be
+ displayed, but @code{:slant italic} will @emph{not} be satisified by
+ the tty display code's automatic substitution of a `dim' face for
+ italic.
