-/*! \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.

-/*!
- 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.
