[HarfBuzz] HarfBuzz Memory Consumption

[Behdad Esfahbod]

Hi everyone,

I put this document together today:

Excerpt:

"The numbers do not need any explanation.  For many common OpenType fonts as
shipped on Windows, ChromeOS, and Android, new HarfBuzz saves over 99% in font
loading memory overhead compared to old HarfBuzz currently used in ChromeOS
and Android."

I hope anyone using old HarfBuzz is convinced to switch over now.

Cheers,
behdad
