671bca785d [glyf] Align glyphs at word boundaries, not long 
Saves two bytes per glyph on average.  Or as Roozbeh reports,
70kb in DroidSansFallbackFull.ttf.

3c89b298c3 Disallow empty glyph name decoded from post table 
But preserve it...

For example, with this font:

https://code.google.com/p/googlefontdirectory/source/browse/ofl/phetsarath/Phetsarath-Regular.ttf

we now get:

    ...
    <GlyphID id="136" name="uni0EDD.am"/>
    <GlyphID id="137" name="uni0EB3.right"/>
    <GlyphID id="138" name="glyph00138"/>
    <GlyphID id="139" name="glyph00139"/>
    <GlyphID id="140" name="glyph00140"/>
    ...
    <GlyphID id="161" name="glyph00161"/>
  </GlyphOrder>

...

  <post>
    <formatType value="2.0"/>
    <italicAngle value="0.0"/>
    <underlinePosition value="-217"/>
    <underlineThickness value="150"/>
    <isFixedPitch value="0"/>
    <minMemType42 value="0"/>
    <maxMemType42 value="0"/>
    <minMemType1 value="0"/>
    <maxMemType1 value="0"/>
    <psNames>
      <!-- This file uses unique glyph names based on the information
           found in the 'post' table. Since these names might not be unique,
           we have to invent artificial names in case of clashes. In order to
           be able to retain the original information, we need a name to
           ps name mapping for those cases where they differ. That's what
           you see below.
            -->
      <psName name="glyph00107" psName=""/>
      <psName name="glyph00138" psName=""/>
      <psName name="glyph00139" psName=""/>
      ...
      <psName name="glyph00161" psName=""/>
    </psNames>

9f23ee4cc8 Change cmap-based duplicate-name resolution from n^2 to linear time 
Similar to 85be2e0a9773acec3c6d14c345b1fd94ab3aa5c3, though much
harder to hit.

4ff0d4b192 Fix post table glyph name dedup logic for edge case 
This is a followup fix to 85be2e0a9773acec3c6d14c345b1fd94ab3aa5c3
Before this change, if some glyph names had a "#-number" suffix in
the post table, we could generate duplicate glyph names.  Fix that,
even though "#" is NOT a valid character in PS glyph names.
