97/* SCALE() mimics code from commit 399b00a99b2bbc1c56a05974c936aa69a08021f5
* concerning a potential division by 0, but instead of doing a * (1/b), it
* does a/b, thus improving the accuracy. With a * (1/b), for a bitmap font
* of size 13, the computed -y_bearing was 0x1.6000000000001p+3 instead of
* 0x1.6p+3 (= 11). This triggered a bug in GNU Emacs (when built against
* cairo), which rounded the value to an integer with ceil().
* Details:
*   https://gitlab.freedesktop.org/cairo/cairo/-/issues/503
*   https://debbugs.gnu.org/cgi/bugreport.cgi?bug=44284
*
* Note that rounding errors are not necessarily expected by applications
* in simple cases like the GNU Emacs one (an identity transformation,
* which should normally leave the inputs unchanged). However, with the
* current cairo code, due to the scaling, there is no guarantee that
* rounding errors will always be avoided at the end. For instance,
* (a/b)*b may be different from a, but this is still better than doing
* (a*(1/b))*b.
*
* According to the commit mentioned above, avoiding a division by zero
* was an attempt to fix
*   https://bugzilla.gnome.org/show_bug.cgi?id=311299
* but this did not actually solve the problem. So it might be possible
* to change SCALE() to just do (a) / (b).

* _cairo_ft_unscaled_font_init:
*
* Initialize a #cairo_ft_unscaled_font_t.
*
* There are two basic flavors of #cairo_ft_unscaled_font_t, one
* created from an FT_Face and the other created from a filename/id
* pair. These two flavors are identified as from_face and !from_face.
*
* To initialize a from_face font, pass filename==%NULL, id=0 and the
* desired face.
*
* To initialize a !from_face font, pass the filename/id as desired
* and face==%NULL.
*
* Note that the code handles these two flavors in very distinct
* ways. For example there is a hash_table mapping
* filename/id->#cairo_unscaled_font_t in the !from_face case, but no
* parallel in the from_face case, (where the calling code would have
* to do its own mapping to ensure similar sharing).

* if it needs to.  You are free to modify or free @pattern after this call.
*
* Creates a new font face for the FreeType font backend based on a
* fontconfig pattern. This font can then be used with
* cairo_set_font_face() or cairo_scaled_font_create(). The
* #cairo_scaled_font_t returned from cairo_scaled_font_create() is
* also for the FreeType backend and can be used with functions such
* as cairo_ft_scaled_font_lock_face().
*
* Font rendering options are represented both here and when you
* call cairo_scaled_font_create(). Font options that have a representation
* in a #FcPattern must be passed in here; to modify #FcPattern
* appropriately to reflect the options in a #cairo_font_options_t, call
* cairo_ft_font_options_substitute().
*
* The pattern's FC_FT_FACE element is inspected first and if that is set,
* that will be the FreeType font face associated with the returned cairo
* font face.  Otherwise the FC_FILE element is checked.  If it's set,
* that and the value of the FC_INDEX element (defaults to zero) of @pattern
* are used to load a font face from file.
*
* If both steps from the previous paragraph fails, @pattern will be passed
* to FcConfigSubstitute, FcDefaultSubstitute, and finally FcFontMatch,
* and the resulting font pattern is used.
*
* If the FC_FT_FACE element of @pattern is set, the user is responsible
* for making sure that the referenced FT_Face remains valid for the life
* time of the returned #cairo_font_face_t.  See
* cairo_ft_font_face_create_for_ft_face() for an example of how to couple
* the life time of the FT_Face to that of the cairo font-face.
*
* Return value: a newly created #cairo_font_face_t. Free with
*  cairo_font_face_destroy() when you are done using it.

* cairo_ft_font_face_create_for_ft_face:
* @face: A FreeType face object, already opened. This must
*   be kept around until the face's ref_count drops to
*   zero and it is freed. Since the face may be referenced
*   internally to Cairo, the best way to determine when it
*   is safe to free the face is to pass a
*   #cairo_destroy_func_t to cairo_font_face_set_user_data()
* @load_flags: flags to pass to FT_Load_Glyph when loading
*   glyphs from the font. These flags are OR'ed together with
*   the flags derived from the #cairo_font_options_t passed
*   to cairo_scaled_font_create(), so only a few values such
*   as %FT_LOAD_VERTICAL_LAYOUT, and %FT_LOAD_FORCE_AUTOHINT
*   are useful. You should not pass any of the flags affecting
*   the load target, such as %FT_LOAD_TARGET_LIGHT.
*
* Creates a new font face for the FreeType font backend from a
* pre-opened FreeType face. This font can then be used with

* also for the FreeType backend and can be used with functions such
* as cairo_ft_scaled_font_lock_face(). Note that Cairo may keep a reference
* to the FT_Face alive in a font-cache and the exact lifetime of the reference
* depends highly upon the exact usage pattern and is subject to external
* factors. You must not call FT_Done_Face() before the last reference to the
* #cairo_font_face_t has been dropped.
*
* As an example, below is how one might correctly couple the lifetime of
* the FreeType face object to the #cairo_font_face_t.
