+<p><a class="link" href="cairo-cairo-font-face-t.html#cairo-font-type-t" title="enum cairo_font_type_t"><span class="type">cairo_font_type_t</span></a> is used to describe the type of a given font
+face or scaled font. The font types are also known as "font
+backends" within cairo.</p>
+<p>The type of a font face is determined by the function used to
+create it, which will generally be of the form
+<code class="function">cairo_<span class="emphasis"><em>type</em></span>_font_face_create()</code>.
+The font face type can be queried with <a class="link" href="cairo-cairo-font-face-t.html#cairo-font-face-get-type" title="cairo_font_face_get_type ()"><code class="function">cairo_font_face_get_type()</code></a></p>
+<p>The various <a class="link" href="cairo-cairo-font-face-t.html#cairo-font-face-t" title="cairo_font_face_t"><span class="type">cairo_font_face_t</span></a> functions can be used with a font face
+of any type.</p>
+<p>The type of a scaled font is determined by the type of the font
+face passed to <a class="link" href="cairo-cairo-scaled-font-t.html#cairo-scaled-font-create" title="cairo_scaled_font_create ()"><code class="function">cairo_scaled_font_create()</code></a>. The scaled font type can
+be queried with <a class="link" href="cairo-cairo-scaled-font-t.html#cairo-scaled-font-get-type" title="cairo_scaled_font_get_type ()"><code class="function">cairo_scaled_font_get_type()</code></a></p>
+<p>The various <a class="link" href="cairo-cairo-scaled-font-t.html#cairo-scaled-font-t" title="cairo_scaled_font_t"><span class="type">cairo_scaled_font_t</span></a> functions can be used with scaled
+fonts of any type, but some font backends also provide
+type-specific functions that must only be called with a scaled font
+of the appropriate type. These functions have names that begin with
+<code class="function">cairo_<span class="emphasis"><em>type</em></span>_scaled_font()</code>
+such as <a class="link" href="cairo-FreeType-Fonts.html#cairo-ft-scaled-font-lock-face" title="cairo_ft_scaled_font_lock_face ()"><code class="function">cairo_ft_scaled_font_lock_face()</code></a>.</p>
+<p>The behavior of calling a type-specific function with a scaled font
+of the wrong type is undefined.</p>
+<p>New entries may be added in future versions.</p>
