    RegisterSyncCallback

    A replacement for RegisterCallback for use with APIs that will call
    the callback on the wrong thread.  Synchronizes with the script's main
    thread via a window message.

    This version tries to emulate RegisterCallback as much as possible
    without using RegisterCallback, so shares most of its limitations,
    and some enhancements that could be made are not.

    Other differences from v1 RegisterCallback:
      - Variadic mode can't be emulated exactly, so is not supported.
      - A_EventInfo can't be set in v1, so is not supported.
      - Fast mode is not supported (the option is ignored).
      - ByRef parameters are allowed (but ByRef is ignored).
      - Throws instead of returning "" on failure.

    RegisterSyncCallback

    A replacement for RegisterCallback for use with APIs that will call
    the callback on the wrong thread.  Synchronizes with the script's main
    thread via a window message.

    This version tries to emulate RegisterCallback as much as possible
    without using RegisterCallback, so shares most of its limitations,
    and some enhancements that could be made are not.

    Other differences from v1 RegisterCallback:
      - Variadic mode can't be emulated exactly, so is not supported.
      - A_EventInfo can't be set in v1, so is not supported.
      - Fast mode is not supported (the option is ignored).
      - ByRef parameters are allowed (but ByRef is ignored).
      - Throws instead of returning "" on failure.

    RegisterSyncCallback

    A replacement for RegisterCallback for use with APIs that will call
    the callback on the wrong thread.  Synchronizes with the script's main
    thread via a window message.

    This version tries to emulate RegisterCallback as much as possible
    without using RegisterCallback, so shares most of its limitations,
    and some enhancements that could be made are not.

    Other differences from v1 RegisterCallback:
      - Variadic mode can't be emulated exactly, so is not supported.
      - A_EventInfo can't be set in v1, so is not supported.
      - Fast mode is not supported (the option is ignored).
      - ByRef parameters are allowed (but ByRef is ignored).
      - Throws instead of returning "" on failure.
