*/
+/*
+ * Theory of keyboard operation
+ *
+ * The remote VNC client sends us a series of key press and release
+ * events identified as X keysyms. (Even Windows clients use X
+ * keysyms; that's just how the protocol works.) We then use our
+ * knowledge of the keyboard layout to translate the keysyms into
+ * keycodes, and use XTEST to send events for the appropriate
+ * keycodes.
+ *
+ *
+ * Keyboard layouts
+ *
+ * The XKEYBOARD extension describes the keyboard as having up to 4
+ * "groups" (layouts), and each key on the keyboard has some number of
+ * "levels" corresponding to combinations of modifier keys. Different
+ * keys may have different numbers of levels, with different meanings.
+ * The "Alt-Gr" key on the keyboard is bound to the keysym
+ * ISO_Level3_Shift, which is a modifer that switches to a level
+ * called "Level3" on some keys.
+ *
+ * The core X protocol (on non-XKB servers) has a simpler model, in
+ * which there are normally 2 groups, and each group has 2 levels
+ * (unshifted and shifted). The "Alt-Gr" key is bound to the keysym
+ * Mode_switch, which is a modifier key that switches to the second
+ * group when it is held down.
+ *
+ * Our model is a simplification of the XKB model that also fits in
+ * well with the core model; there are between 1 and 4 groups
+ * (keyboard layouts), and each group has exactly 4 levels (plain,
+ * Shift or NumLock, Alt-Gr, and Shift+Alt-Gr).
+ *
+ *
+ * Details of key event processing
+ *
+ * When a modifier keypress is received, vino sends a KeyPress to the
+ * server, and when the corresponding keyrelease event is received, it
+ * sends a KeyRelease to the server. But for non-modifier keys, it
+ * always sends both a KeyPress and a KeyRelease together when it
+ * receives just the keypress event. (This is because we assume that
+ * the client side will handle "key repeat", and if we left the key
+ * pressed down on the server as well, we'd get double repeating.)
+ *
+ * Shift and Alt-Gr are treated slightly different from the other
+ * modifier keys; they are considered to be just implementation
+ * details of how you type a particular keysym. Eg, if you type
+ * Control+Shift+? (on a US keyboard), you're typing Control because
+ * you want the Control key to be pressed, but you're only typing
+ * Shift because it's required to get a "?" rather than a "/".
+ * Different keyboard layouts require Shift and Alt-Gr to be used for
+ * different keysyms, so if the client and server keyboards are not of
+ * the same type, vino will sometimes need to send fake press and
+ * release events for Shift and Alt-Gr in order to be able to type the
+ * keys the client intended to type. (On keys that have no shifted
+ * state, like the arrow and function keys, Shift and Alt-Gr behave
+ * as ordinary modifiers, the same way Control and Alt do.)
+ *
+ * Two further bits of special behavior are needed for NumLock; first,
+ * the second key level, which is normally "Shift", actually
+ * corresponds to "NumLock" on keypad keys. Second, since the server's
+ * NumLock key could plausibly be locked in either state, we need to
+ * take its state into account when typing keypad keys. If the server
+ * supports XKB, we use the XkbStateNotify event to track NumLock
+ * state changes. If the server doesn't support XKB, we have to
+ * explicitly query the modifier state any time the client types a
+ * keypad key.
+ *
+ * On servers that support XKB, we also have to worry about multiple
+ * keyboard layouts. We need to keep track of what keysyms are
+ * available in what layouts, and what layout (or "group") the server
+ * is currently using. When a keysym arrives, we look for a way to
+ * type that keysym in the current group, but if it's only available
+ * in a different group, we have to change groups temporarily to type
+ * it (in the same way we have to temporarily change modifiers
+ * sometimes). Doing this programmatically is a little bit tricky; XKB
+ * provides XkbLatchGroup(), but if the layout doesn't use
+ * "XkbWrapIntoRange" semantics, then that can only switch to
+ * higher-numbered groups. Alternatively, we could find the
+ * group-switching keys on the keyboard and use them the way we use
+ * the Shift and Alt-Gr keys, but there are several different ways
+ * that group switching could be set up, and we'd need to support all
+ * of them. Anyway, all of the layouts in the xkeyboard-config package
+ * use XkbWrapIntoRange, so XkbLatchGroup() works for us in that case,
+ * so we just require that, and don't support multiple groups if the
+ * layout uses XkbRedirectIntoRange or XkbClampIntoRange.
+ *
+ * Two additional problems show up with Windows-based clients; first,
+ * Windows considers Alt-Gr to be equivalent to Control_L + Alt_R, so
+ * we have to translate that. Second, Windows clients never send
+ * events for dead keys. Instead, if you type a dead acute accent key
+ * followed by "e", it sends a single keypress event for XK_eacute.
+ * This works fine when the current keyboard layout has a key for that
+ * precomposed keysym, but if it doesn't, we need to decompose it back
+ * into multiple keypresses. There is no guarantee that the
+ * decompositions we use will actually work, but since compositions
+ * happen in the library, not the server, there is no way to find out
+ * 100% reliably what compositions are available to the window
+ * currently being typed into, so this is the best we can do.
