 /* This tests Mozilla's Text Services Framework implementation (bug #88831)
  *
  * The Mozilla implementation interacts with the TSF system through a
  * system-provided COM interface, ITfThreadMgr. This tests works by swapping
  * the system version of the interface with a custom version implemented in
  * here. This way the Mozilla implementation thinks it's interacting with the
  * system but in fact is interacting with this test program. This allows the
  * test program to access and test every aspect of the Mozilla implementation.
