+/*
+ Policy:
+
+ The XIM is of the device, by the device, for the device.
+ The XIC is of each frame, by each frame, for each frame.
+ The exceptions are:
+ 1. Activate XICs on poor frames when the XIM is back.
+ 2. Deactivate all the XICs when the XIM go down.
+
+ Methods:
+
+ - Register a callback for an XIM when the X device is being initialized.
+ XIM_init_device (d) { XRegisterIMInstantiateCallback (); }
+ The "XRegisterIMInstantiateCallback" is called when an XIM become
+ available on the X display.
+
+ - Catch the XIC when the frame is being initialized if XIM was available.
+ XIM_init_frame (f) { ... XCreateIC (); ... }
+
+ - Release the XIC when the frame is being closed.
+ XIM_delete_frame (f) { ... FRAME_X_XIC (f) = NULL; ... }
+ "XIM_delete_frame" is a "DestroyCallback" function declared in
+ XIM_init_frame ();
+
+ - Release all the XICs when the XIM was down accidentally.
+ In IMDestroyCallback:
+ DEVICE_FRAME_LOOP (...) { FRAME_X_XIC (f) = NULL; }
+
+ - Re-enable XIC for all the frames which doesn't have XIC when the XIM
+ is back.
+ In IMInstantiateCallback:
+ DEVICE_FRAME_LOOP (...) { XIM_init_frame (f); }
+
+
+ Note:
+
+ - Currently, we don't use XDestroyIC because of _XimProtoCloseIM
+ (internally registered as im->methods->close) does "Xfree (ic)".
