+ * The OpenType specification v1.8.3 says:
+ *
+ * [OS/2's] sTypoAscender, sTypoDescender and sTypoLineGap fields
+ * are intended to allow applications to lay out documents in a
+ * typographically-correct and portable fashion.
+ *
+ * This is somewhat at odds with the decades of backwards
+ * compatibility, operating systems and applications doing whatever
+ * they want, not to mention broken fonts.
+ *
+ * Not all fonts have an OS/2 table; in this case, we take the values
+ * in the horizontal header, although there is nothing stopping the
+ * values from being unreliable. Even with a OS/2 table, certain fonts
+ * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
+ * and instead correctly set usWinAscent and usWinDescent.
+ *
+ * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
+ * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have
+ * the same values in their sTypo* fields, except ARIALNB.ttf which
+ * sets them to 0. All of them have different usWinAscent/Descent
+ * values. The OS/2 table therefore cannot be trusted for computing the
+ * text height reliably.
+ *
+ * As a compromise, do the following:
+ *
+ * 1. If the OS/2 table exists and the fsSelection bit 7 is set
+ * (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
+ * 2. Otherwise, use the `hhea' table's metrics.
+ * 3. If they are zero and the OS/2 table exists,
+ * 1. use the OS/2 table's sTypo* metrics if they are non-zero.
+ * 2. Otherwise, use the OS/2 table's usWin* metrics.

+ * artifacts in many glyphs. So, these rules make some glyphs render
+ * better than they do in the MS rasterizer.

+ * "" string or 0 int/char indicates to apply to all glyphs.
