elisp: Precalculated Fontification

 
 22.6.6 Precalculated Fontification
 ----------------------------------
 
 Some major modes such as ‘list-buffers’ and ‘occur’ construct the buffer
 text programmatically.  The easiest way for them to support Font Lock
 mode is to specify the faces of text when they insert the text in the
 buffer.
 
    The way to do this is to specify the faces in the text with the
 special text property ‘font-lock-face’ (Special Properties).
 When Font Lock mode is enabled, this property controls the display, just
 like the ‘face’ property.  When Font Lock mode is disabled,
 ‘font-lock-face’ has no effect on the display.
 
    It is ok for a mode to use ‘font-lock-face’ for some text and also
 use the normal Font Lock machinery.  But if the mode does not use the
 normal Font Lock machinery, it should not set the variable
 ‘font-lock-defaults’.
