// This is the Cicero UIF Library, used to support the IME UI interface.
// The Cicero UIF Library implements some GUI parts for IMEs and Language Bar.
// The GUI parts of the UIF Library requires special handling because:
//
// 1. To avoid interfering with IME input, the GUI part should not receive focus.
// 2. The IME popup window has WS_DISABLED style, so it cannot receive mouse messages
//    directly.
