+<p>Sets the horizontal and vertical scale of a font.</p>
+<p>The font scale is a number related to, but not the same as,
+font size. Typically the client establishes a scale factor
+to be used between the two. For example, 64, or 256, which
+would be the fractional-precision part of the font scale.
+This is necessary because <a class="link" href="harfbuzz-hb-common.html#hb-position-t" title="hb_position_t"><span class="type">hb_position_t</span></a> values are integer
+types and you need to leave room for fractional values
+in there.</p>
+<p>For example, to set the font size to 20, with 64
+levels of fractional precision you would call
+<code class="literal">hb_font_set_scale(font, 20 * 64, 20 * 64)</code>.</p>
+<p>In the example above, even what font size 20 means is up to
+you. It might be 20 pixels, or 20 points, or 20 millimeters.
+HarfBuzz does not care about that.  You can set the point
+size of the font using <a class="link" href="harfbuzz-hb-font.html#hb-font-set-ptem" title="hb_font_set_ptem ()"><code class="function">hb_font_set_ptem()</code></a>, and the pixel
+size using <a class="link" href="harfbuzz-hb-font.html#hb-font-set-ppem" title="hb_font_set_ppem ()"><code class="function">hb_font_set_ppem()</code></a>.</p>
+<p>The choice of scale is yours but needs to be consistent between
+what you set here, and what you expect out of <a class="link" href="harfbuzz-hb-common.html#hb-position-t" title="hb_position_t"><span class="type">hb_position_t</span></a>
+as well has draw / paint API output values.</p>
+<p>Fonts default to a scale equal to the UPEM value of their face.
+A font with this setting is sometimes called an "unscaled" font.</p>
