- * keyEvent() - work out the best keycode corresponding to the keysym sent by
- * the viewer. This is non-trivial because we can't assume much about the
- * local keyboard layout. We must also find out which column of the keyboard
- * mapping the keysym is in, and alter the shift state appropriately. Column 0
- * means both shift and "mode_switch" (AltGr) must be released, column 1 means
- * shift must be pressed and mode_switch released, column 2 means shift must be
- * released and mode_switch pressed, and column 3 means both shift and
- * mode_switch must be pressed.
- *
- * Magic, which dynamically adds keysym<->keycode mapping depends on X.Org
- * version. Quick explanation of that "magic":
- *
- * 1.5
- * - has only one core keyboard so we have to keep core keyboard mapping
- * synchronized with vncKeyboardDevice. Do it via SwitchCoreKeyboard()
- *
- * 1.6 (aka MPX - Multi pointer X)
- * - multiple master devices (= core devices) exists, keep vncKeyboardDevice
- * synchronized with proper master device
