- implement horizontal line wrap
If Line Wrap is enabled for the terminal, the traditional behaviour is kept. Otherwise, a horizontal scroll bar is added and 80 columns are assumed. TODO: - handle modes when there's no vertical scroll bar or it's on the left side - initialize correctly (currently, sometimes moving the scrollbar must be done at first)

/*! \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.

/*! \class Widget
\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 Widget.
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 Widget 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.
