Can you rev the version number since you changed this interface?

[Josh Horwich, 2012/07/25 22:00:43]

Based on offline conversation, I'll leave the version number the same as we are
appending a method and leaving the rest of the struct alone - this isn't ideal
since consumers of this API (PDF viewer) won't be able to disambiguate
older/newer, however this lets us avoid adding multiple versions for things like
pepper_flash_component_installer.cc  .
