  Log Message:
  webkit-gtk: Update to 2.28.4

  pkgsrc changes:
    - Define non-standard __WORDSIZE if not already defined (at the moment the
      patches directly patch problematic files where __WORDSIZE is used, it would
      be probably nicer to find a common place to define it).

  Changes:
  2.28.4
  ------
    - Fix several crashes and rendering issues.
