+ An arbitrary long scroll.
+
+ One can modify the scroll only by adding either cells

+
+ The model is that of an arbitrary wide typewriter scroll
+ in that the scroll is a serie of lines and each line is
+ a serie of cells with no overwriting permitted.
+
+ The implementation provides arbitrary length and numbers
+ of cells and line/column indexed read access to the scroll
+ at constant costs.
+
+FIXME: some complain about the history buffer comsuming the
+ memory of their machines. This problem is critical
+ since the history does not behave gracefully in cases
+ where the memory is used up completely.
+
+ I put in a workaround that should handle it problem
+ now gracefully. I'm not satisfied with the solution.
+
+FIXME: Terminating the history is not properly indicated
+ in the menu. We should throw a signal.
+
+FIXME: There is noticable decrease in speed, also. Perhaps,
+ there whole feature needs to be revisited therefore.

+ It is a complete passive device, driven by the emulation decoder
+ (TEmuVT102). By this it forms in fact an ADT, that defines operations
+ on a rectangular image.
+
+ It does neither know how to display its image nor about escape sequences.
+ It is further independent of the underlying toolkit. By this, one can even
+ use this module for an ordinary text surface.
+
+ Since the operations are called by a specific emulation decoder, one may
+ collect their different operations here.
+
+ The state manipulated by the operations is mainly kept in `image', though
+ it is a little more complex bejond this. See the header file of the class.

+/*! \class TEWidget
+
+ \brief Visible screen contents
+
+ This class is responsible to map the `image' of a terminal emulation to the
+ display. All the dependency of the emulation to a specific GUI or toolkit is
+ localized here. Further, this widget has no knowledge about being part of an
+ emulation, it simply work within the terminal emulation framework by exposing
+ size and key events and by being ordered to show a new image.
+
+ <ul>
+ <li> The internal image has the size of the widget (evtl. rounded up)
+ <li> The external image used in setImage can have any size.
+ <li> (internally) the external image is simply copied to the internal
+ when a setImage happens. During a resizeEvent no painting is done
+ a paintEvent is expected to follow anyway.
+ </ul>
+
+ \sa TEScreen \sa Emulation
+*/
+
+/* FIXME:
+ - 'image' may also be used uninitialized (it isn't in fact) in resizeEvent
+ - 'font_a' not used in mouse events
+ - add destructor
+*/
+
+/* TODO
+ - evtl. be sensitive to `paletteChange' while using default colors.
+ - set different 'rounding' styles? I.e. have a mode to show clipped chars?

+/*!
+ Three different operations can be performed using the mouse, and the
+ routines in this section serve all of them:
+
+ 1) The press/release events are exposed to the application
+ 2) Marking (press and move left button) and Pasting (press middle button)
+ 3) The right mouse button is used from the configuration menu
+
+ NOTE: During the marking process we attempt to keep the cursor within
+ the bounds of the text as being displayed by setting the mouse position
+ whenever the mouse has left the text area.
+
+ Two reasons to do so:
+ 1) QT does not allow the `grabMouse' to confine-to the TEWidget.
+ Thus a `XGrapPointer' would have to be used instead.
+ 2) Even if so, this would not help too much, since the text area
+ of the TEWidget is normally not identical with it's bounds.
+
+ The disadvantage of the current handling is, that the mouse can visibly
+ leave the bounds of the widget and is then moved back. Because of the
+ current construction, and the reasons mentioned above, we cannot do better
+ without changing the overall construction.

+/* Incoming Bytes Event pipeline
+
+ This section deals with decoding the incoming character stream.
+ Decoding means here, that the stream is first seperated into `tokens'
+ which are then mapped to a `meaning' provided as operations by the
+ `TEScreen' class or by the emulation class itself.
+
+ The pipeline proceeds as follows:
+
+ - Tokenizing the ESC codes (onRcvChar)
+ - VT100 code page translation of plain characters (applyCharset)
+ - Interpretation of ESC codes (tau)
+
+ The escape codes and their meaning are described in the
+ technical reference of this program.
+*/
+
+// Tokens ------------------------------------------------------------------ --
+
+/*
+ Since the tokens are the central notion if this section, we've put them
+ in front. They provide the syntactical elements used to represent the
+ terminals operations as byte sequences.
+
+ They are encodes here into a single machine word, so that we can later
+ switch over them easily. Depending on the token itself, additional
+ argument variables are filled with parameter values.
+
+ The tokens are defined below:
+
+ - CHR - Printable characters (32..255 but DEL (=127))
+ - CTL - Control characters (0..31 but ESC (= 27), DEL)
+ - ESC - Escape codes of the form <ESC><CHR but `[]()+*#'>
+ - ESC_DE - Escape codes of the form <ESC><any of `()+*#%'> C
+ - CSI_PN - Escape codes of the form <ESC>'[' {Pn} ';' {Pn} C
+ - CSI_PS - Escape codes of the form <ESC>'[' {Pn} ';' ... C
+ - CSI_PR - Escape codes of the form <ESC>'[' '?' {Pn} ';' ... C
+ - VT52 - VT52 escape codes
+ - <ESC><Chr>
+ - <ESC>'Y'{Pc}{Pc}
+ - XTE_HA - Xterm hacks <ESC>`]' {Pn} `;' {Text} <BEL>
+ note that this is handled differently
+
+ The last two forms allow list of arguments. Since the elements of
+ the lists are treated individually the same way, they are passed
+ as individual tokens to the interpretation. Further, because the
+ meaning of the parameters are names (althought represented as numbers),
+ they are includes within the token ('N').

+/*! \class TEmulation
+
+ \brief Mediator between TEWidget and TEScreen.
+
+ This class is responsible to scan the escapes sequences of the terminal
+ emulation and to map it to their corresponding semantic complements.
+ Thus this module knows mainly about decoding escapes sequences and
+ is a stateless device w.r.t. the semantics.
+
+ It is also responsible to refresh the TEWidget by certain rules.
+
+ \sa TEWidget \sa TEScreen
+
+ \par A note on refreshing
+
+ Although the modifications to the current screen image could immediately
+ be propagated via `TEWidget' to the graphical surface, we have chosen
+ another way here.
+
+ The reason for doing so is twofold.
+
+ First, experiments show that directly displaying the operation results
+ in slowing down the overall performance of emulations. Displaying
+ individual characters using X11 creates a lot of overhead.
+
+ Second, by using the following refreshing method, the screen operations
+ can be completely separated from the displaying. This greatly simplifies
+ the programmer's task of coding and maintaining the screen operations,
+ since one need not worry about differential modifications on the
+ display affecting the operation of concern.
+
+ We use a refreshing algorithm here that has been adoped from rxvt/kvt.
+
+ By this, refreshing is driven by a timer, which is (re)started whenever
+ a new bunch of data to be interpreted by the emulation arives at `onRcvBlock'.
+ As soon as no more data arrive for `BULK_TIMEOUT' milliseconds, we trigger
+ refresh. This rule suits both bulk display operation as done by curses as
+ well as individual characters typed.
+ (BULK_TIMEOUT < 1000 / max characters received from keyboard per second).
+
+ Additionally, we trigger refreshing by newlines comming in to make visual
+ snapshots of lists as produced by `cat', `ls' and likely programs, thereby
+ producing the illusion of a permanent and immediate display operation.
+
+ As a sort of catch-all needed for cases where none of the above
+ conditions catch, the screen refresh is also triggered by a count
+ of incoming bulks (`bulk_incnt').
+*/
+
+/* FIXME
+ - evtl. the bulk operations could be made more transparent.
