-<para>
-Low Bandwidth X (LBX) is a network-transparent protocol for running X Window
-System applications over transport channels whose bandwidth and latency are
-significantly worse than that used in local area networks. It combines a
-variety of caching and reencoding techniques to reduce the volume of data that
-must be sent over the wire. It can be used with existing clients by placing a
-proxy between the clients and server, so that the low bandwidth/high latency
-communication occurs between the proxy and server.

-This extension was designed and implemented by Jim Fulton, David Lemke, Keith
-Packard, and Dale Tonogai, all of Network Computing Devices (NCD). Chris Kent
-Kantarjiev (Xerox PARC) participated in early design discussions. Ralph Mor (X
-Consortium) designed and implemented additional sections. Donna Converse (X
-Consortium) authored the protocol description and encoding from design notes
-and the implementation. Ray Tice (X Consortium) resolved the open issues in the
-design and specification. Bob Scheifler (X Consortium) helped out in many areas.

-<title>Description</title>
-
-<para>
-The design center for LBX is to use a proxy as an intermediary between the
-client and server. The proxy reencodes and compresses requests, events, replies
-and errors, as well as the resulting data stream. Additionally, the proxy can
-cache information from the server to provide low-latency replies to clients.
-This reply generation by the proxy is known as short-circuiting. A proxy can
-handle multiple clients for a given server, but does not prevent clients from
-connecting directly to the server. The design allows the proxy to multiplex
-multiple clients into a single data stream to the server.
-</para>
-
-
-<para>
-Much of LBX is implemented as an extension. The compression and reencoding
-changes can be isolated to the transport and dispatch portions of the server,
-while short-circuiting requires minor changes to the server’s colormap and
-property code.
-</para>
-
-
-<para>
-LBX employs several different compression and short-circuiting methods. Use of
-these methods is negotiable, and in some cases, the algorithm used by a given
-method is negotiable as well. LBX also provides for negotiation of extensions
-to LBX.

-<title>Tags</title>
-
-<para>
-Tags are used to support caching of large data items that are expected to be
-queried multiple times. Such things as the keyboard map and font metrics are
-often requested by multiple clients. Rather than send the data each time, the
-first time the data is sent it includes a tag. The proxy saves this data, so
-that subsequent requests can send only the tag to refer to that same data. The
-different types of tags are used for connection information, keyboard maps,
-modifier maps, fonts information and properties.
-</para>
-
-
-<para>
-Tag usage is negotiated as a boolean in the <emphasis>
-LbxStartProxy</emphasis>
- message. The proxy controls how many tags are stored in the proxy. The server
-may wish to observe the proxy’s InvalidateTag behavior to limit how many tags
-are cached at any one time. Tagged data is not shared across types of tags, but
-the number space used for the tag ids is. The tag ids are generated by the
-server.
-</para>
-
-
-<para>
-The X server keeps track of what tags are known to the proxy. The proxy can
-invalidate a tag if no tag bearing replies of that type are pending. The proxy
-sends an <emphasis>
-LbxInvalidateTag</emphasis>
- message to release the tagged data. The proxy must not invalidate connection
-tags unless instructed to do so by the server.
-</para>
-
-
-<para>
-If the server wishes to discard tagged data, it must either have received an
-<emphasis>
-LbxInvalidateTag</emphasis>
- request from the proxy or send an <emphasis>
-LbxInvalidateTag</emphasis>
- event to the proxy for that tag.
-</para>
-
-
-<sect3 id='tag_substitution_in_requests'>
-<title>Tag Substitution in Requests</title>
-
-<para>
-Many substitution requests have a tag field, followed by fields marked
-optional. For these requests, if the optional fields are present, the
-data in them is stored in the indicated tag, unless the tag is 0. If
-the optional fields are absent, the tag field indicates the tag that
-contains the data for the &quot;optional&quot; fields.
-</para>
-
-
-</sect3>
-<sect3 id='property_tags'>
-<title>Property Tags</title>
-
-<para>
-Property data makes special use of tags. A common use of properties is for
-inter-client communication. If both clients use the proxy, it is wasteful to
-send the data to the server and then back, when the server may never need it.
-<emphasis>
-LbxChangeProperty</emphasis>
- request does the same work as the core <emphasis>
-ChangeProperty</emphasis>
- request, but it does not send the data. The reply to this request contains a
-tag id corresponding to the data. If the property information is used locally,
-the server responds to <emphasis>
-LbxGetProperty</emphasis>
- with the tag, and the property data need never be sent to the server. If the
-server does require the data, it can issue an <emphasis>
-LbxQueryTag</emphasis>
- message. The proxy can also send the data on at any time if it judges it
-appropriate (i.e., when the wire goes idle). Since the proxy owns the property
-data, it must not invalidate the tag before sending the data back to the server
-via an <emphasis>
-LbxTagData</emphasis>
- request.

-<sect2 id='short_circuiting'>
-<title>Short-circuiting</title>
-
-<para>
-Short-circuiting is used to handle constant data. This includes atoms, color
-name/RGB mappings, and <emphasis>
-AllocColor</emphasis>
- calls. Atoms and color name/RGB mappings stay constant for the life of the
-server. <emphasis>
-AllocColor</emphasis>
-<emphasis>
- </emphasis>
-replies are constant for each colormap. Short-circuiting replaces round-trip
-requests with one-way requests, and can sometimes use one in place of many.
-</para>
-
-
-<para>
-Atoms are used heavily for ICCCM communication. Once the proxy knows the string
-to atom mapping, it has no need to send subsequent requests for this atom to
-the server.
-</para>
-
-
-<para>
-Colorname/RGB mappings are constant, so once the proxy sees the response from
-<emphasis>
-LookupColor</emphasis>
-, it need not forward any subsequent requests.
-</para>
-
-
-<para>
-Clients often use the same color cells, so once a read-only color allocation
-has occurred, the proxy knows what RGB values should be returned to the client.
-The proxy doesn't need to forward any <emphasis>
-AllocColor</emphasis>
- requests it can resolve, but it must tell the server to modify the color
-cell's reference count. <emphasis>
-LbxIncrementPixel</emphasis>
- is used to support this.
-</para>
-
-
-<para>
-For all three classes of short-circuiting, the proxy must still tell the server
-a request has occurred, so that the request sequence numbers stay in sync. This
-is done with <emphasis>
-LbxModifySequence</emphasis>
-.
-</para>
-
-
-<para>
-Sequence numbers cause the major complication with short-circuiting. X
-guarantees that any replies, events or errors generated by a previous request
-will be sent before those of a later request. This means that any requests that
-can be handled by the proxy must have their reply sent after any previous
-events or errors.
-</para>
-
-
-<para>
-If a proxy’s applications do not require strict adherence to the X protocol
-ordering of errors or events, a proxy might provide further optimization by
-avoiding the overhead of maintaining this ordering, however, the resulting
-protocol is not strictly X11 compliant.

-and <emphasis>ImageText16</emphasis> requests. If the request can be
-reencoded, it may be replaced by an equivalent LBX form of the request.
-The requests are reencoded by attempting to reduce 2-byte coordinate,
-length, width and angle fields to 1 byte. Where applicable, the
-coordinate mode is also converted to <emphasis>Previous</emphasis>
- to improve the compressibility of the resulting data. In image requests,
-the image data may also be compressed.

-
-</sect2>
-<sect2 id='motion_events'>
-<title>Motion events</title>
-
-<para>
-To prevent clogging the wire with <emphasis>MotionNotify</emphasis>
- events, the server and proxy work together to control the number
-of events on the wire. This is done with the
-<emphasis>LbxAllowMotion</emphasis>
- request. The request adds an amount to an allowed motion count in
-the server, which is kept on a per-proxy basis. Every motion notify
-event sent to the proxy decrements the allowed motion counter. If
-the allowed motion count is less than or equal to zero, motion
-events not required by the X protocol definition are not sent to the
-proxy. The allowed motion counter has a minimum value of -2^31.

-
-</sect2>
-<sect2 id='event_squishing'>
-<title>Event Squishing</title>
-
-<para>
-In the core protocol, all events are padded as needed to be 32 bytes long. The
-LBX extension reduces traffic by removing padding at the end of events, and
-implying the event length from its type. This is known as squishing.

-<sect2 id='master_client_'>
-<title>Master Client </title>
-
-<para>
-When the initial X connection between the proxy and the server is converted to

-some tag messages are sent in the context of the master client.
-</para>
-
-
-</sect2>
-<sect2 id='multiplexing_of_clients'>
-<title>Multiplexing of Clients</title>
-
-<para>
-The LBX proxy multiplexes the data streams of all its clients into one stream,
-and then splits them apart again when they are received. The <emphasis>
-LbxSwitch</emphasis>
- message is used to tell each end which client is using the wire at the time.
-</para>
-
-
-<para>
-The server should process delta requests in the order that they appear on the
-LBX connection. If the server does not maintain the interclient request order
-for requests sent by the proxy, it must still obey the semantics implied by the
-interclient request order so that the delta cache functions correctly.
-</para>
-
-
-<para>
-The server can affect the multiplexing of clients by the proxy using the
-<emphasis>
-LbxListenToOne</emphasis>
- and <emphasis>
-LbxListenToAll</emphasis>
- messages. This is useful during grabs, since the master connection can not be
-blocked during grabs like other clients. The proxy is responsible for tracking
-server grabs issued by its clients so that the proxy can multiplex the client
-streams in an order executable by the server.
-</para>
-
-
-<para>
-Replies must be ordered in the multiplexed data stream from the server to the
-proxy such that the reply carrying tagged data precedes replies that refer to
-that tagged data.
-</para>
-
-
-</sect2>
-<sect2 id='swapping'>
-<title>Swapping</title>
-
-<para>
-Swapping is handled as with any X extension, with one caveat. Since a proxy can
-be supporting clients with different byte orders, and they all share the same
-wire, the length fields of all messages between the server and proxy are
-expressed in the proxy byte order. This prevents any problems with length
-computation that may occur when clients are switched.
-</para>
-
-
-</sect2>
-<sect2 id='delta_cache'>
-<title>Delta cache</title>
-
-<para>
-LBX takes advantage of the fact that an X message may be very similar to one
-that has been previously sent. For example, a <emphasis>
-KeyPress</emphasis>
- event may differ from a previous <emphasis>
-KeyPress</emphasis>
- event in just a few bytes. By sending just the bytes that differ (or
-"deltas"), the number of bytes sent over the wire can be substantially reduced.
-Delta compaction is used on requests being sent by the proxy as well as on
-replies and events being sent by the server.
-</para>
-
-
-<para>
-The server and the proxy each keep per-proxy request and response caches. The
-response cache contains events, errors and replies. All messages are saved in
-the appropriate delta cache if they are of an appropriate type and more than 8
-bytes long but fit within the delta cache. The number of entries in the delta
-cache and the maximum saved message size are negotiated in the <emphasis>
-LbxStartProxy</emphasis>
- request.

-. The message carried by a <emphasis>

-message is also cached, if it meets the other requirements. Messages after the

-extension. If the extension involves additional event types, the base event
-type code is returned. Otherwise, zero is returned. The format of events is
-specific to the extension. If the extension involves additional error codes,
-the base error code is returned. Otherwise, zero is returned. The format of

-In addition, the number of requests defined by the named extension is returned.
-If the number of requests is nonzero, and if the information is available,
-reply-mask and event-mask will be included in the reply. The reply-mask
-represents a bit-wise one-to-one correspondence with the extension requests.
-The least significant bit corresponds to the first request, and the next bit
-corresponds to the next request, and so on. Each element in the list contains
-eight meaningful bits, except for the last element, which contains eight or
-fewer meaningful bits. Unused bits are not guaranteed to be zero. The bit
-corresponding to a request is set if the request could generate a reply,
-otherwise it is zero. In the same way, the event-mask represents a bit-wise
-one-to-one correspondence with the extension requests. A bit is set if the
-corresponding request could result in the generation of one or more extension
-or X11 events. If reply-mask is present in the reply, event-mask will also be
-present.

-occur multiple times in the start proxy message, since multiple extensions can
-be negotiated. The reply to an extension option contains the zero-based index

-The proxy assigns each virtual connection a unique identifier using the
-<emphasis>

-). client-id 0 is reserved for the proxy control connection. An <emphasis>

-This request asks the server for control of allocating new colormap cells in
-the specified colormap. The server grants control by replying to this request.
-If no changes have occurred since the last time this proxy grabbed this
-colormap, then the <emphasis>

- field of the reply is set to true, and the optional fields are not sent.
-Otherwise, the current contents of the colormap are placed in the reply, as

-</para>
-

-<para>
-Once the proxy has received the reply, it can use the <emphasis>
-LbxAllocColor</emphasis>
- request to allocate new colormap cells without the performance penalty of
-round trips. The proxy is still permitted to use the normal colormap and
-<emphasis>
-LbxIncrementPixel</emphasis>
- requests while the colormap is grabbed. The grab is valid across all virtual
-connections of the proxy.
-</para>
-
-
-<para>
-The <emphasis>

-<para>
-The server and other proxies may not allocate new colormap cells in the

-the visual.
-</para>
-
-
-<para>
-The <emphasis>
-bits-per-rgb</emphasis>
- value is one less than the bits-per-rgb-value field of the visual that the

-This request is sent to the server when the client sends an X <emphasis>

-request through the proxy. The size of the data is sent with this request, but
-not the property data itself. The server reply contains a tag identifier for
-the data, which is stored in the proxy. The proxy must not discard this data
-before it is sent to the server, or invalidated by the server. This means that
-before issuing an <emphasis>
-LbxStopProxy</emphasis>
- request, or exiting, the proxy must send Lbx<emphasis>
-TagData</emphasis>

-The syntax and types used in the encoding are taken from the X protocol

-</para>
-
-
-<para>
-As in the X protocol, in various cases, the number of bytes occupied by a
-component will be specified by a lowercase single-letter variable name instead
-of a specific numeric value, and often some other component will have its value
-specified as a simple numeric expression involving these variables. Components
-specified with such expressions are always interpreted as unsigned integers.
-The scope of such variables is always just the enclosing request, reply, error,
-event, or compound type structure.

-For unused bytes, the encode-form is:
-</para>
-
-<literallayout>

-If the number of unused bytes is variable, the encode-form typically is:

-p            unused, p=pad(E)

-In many of the encodings, the length depends on many variable length fields.
