+ *
+ * When a #cairo_font_face_t is created from a #hb_face_t using

+ * factor defines how the scale set on such #hb_font_t objects
+ * relates to the font-matrix (as such font size) of the cairo
+ * scaled-font.
+ *
+ * If the scale-factor is zero (default), then the scale of the
+ * #hb_font_t object will be left at default, which is the UPEM
+ * value of the respective #hb_face_t.
+ *
+ * If the scale-factor is set to non-zero, then the X and Y scale
+ * of the #hb_font_t object will be respectively set to the

+ * of the cairo scaled-font being created.
+ *
+ * When using the hb_cairo_glyphs_from_buffer() API to convert the
+ * HarfBuzz glyph buffer that resulted from shaping with such a #hb_font_t,
+ * if the scale-factor was non-zero, you can pass it directly to
+ * that API as both X and Y scale factors.
+ *
+ * If the scale-factor was zero however, or the cairo face was
+ * created using the alternative constructor
+ * hb_cairo_font_face_create_for_font(), you need to calculate the
+ * correct X/Y scale-factors to pass to hb_cairo_glyphs_from_buffer()
+ * by dividing the #hb_font_t X/Y scale-factors by the
+ * cairo scaled-font's scale-matrix XX/YY components respectively
+ * and use those values.  Or if you know that relationship offhand

+ *
+ * The @num_glyphs argument should be preset to the number of glyph entries available

+ * allocated glyph array using cairo_glyph_free().  The caller will also free
+ * the original value of @glyphs, so this function shouldn't do so.
+ *
+ * If @clusters is not `NULL`, then @num_clusters and @cluster_flags
+ * should not be either, and @utf8 must be provided, and cluster
+ * mapping will be computed. The semantics of how
+ * cluster array allocation works is similar to the glyph array.  That is,
+ * if @clusters initially points to a non-`NULL` value, that array may be used
+ * as a cluster buffer, and @num_clusters points to the number of cluster
+ * entries available there.  If the provided cluster array is too short for
+ * the conversion (or for convenience), a new cluster array may be allocated
+ * using cairo_text_cluster_allocate() and placed in @clusters.  In this case,
+ * the original value of @clusters will still be freed by the caller.  Upon
+ * return, @num_clusters will contain the number of generated clusters.
+ * If the value @clusters points at has changed after the call, the caller
+ * will free the allocated cluster array using cairo_text_cluster_free().
+ *
+ * See hb_cairo_font_face_set_scale_factor() for the details of
+ * the @scale_factor argument.
+ *
+ * The returned @glyphs vector actually has `@num_glyphs + 1` entries in
