Why is the default for GTK being changed here?

[Xianzhu, 2012/06/26 12:46:45]

Though GTK had a different value here, the value was not used as it is not sent
to WebKit or Skia. In WebKit, autohint is set to true. To keep the original
behavior unchanged, I changed the value here to true as the value is now sent to
WebFontRendering::setAutoHint().

Was WebKit always turning autohinting on automatically?  If so, sorry for
missing it.  My intent was to disable autohinting on GTK, as I think that that
matches Ubuntu's default settings.
