* Shows whether recalculation is necessary.
* If this cell must be recalculated for some reason, for example the user
* entered a new formula, then this flag is set. If @ref #bFormula is false
* nothing will happen at all.
*
* Progress
* Tells whether this cell it currently under calculation.
* If a cell thats 'progressFlag' is set is told to calculate we
* have detected a circular reference and we must stop calulating.
*
* UpdatingDeps
* Tells whether we've already calculated the reverse dependancies for this
* cell. Similar to the Progress flag but it's for when we are calculating
* in the reverse direction.
* @see updateDependancies()
*
* DisplayDirty - TODO - is this unused now??
* If this flag is set, then it is known that this cell has to be updated
* on the display. This means that somewhere in the calling stack there is a
* function which will call @ref Sheet::updateCell once it retains
* the control. If a function changes the contents/layout of this cell and this
* flag is not set, then the function must set it at once. After the changes
* are done the function must call <tt>m_pSheet->updateCell(...).
* The flag is cleared by the function format()->sheet()->updateCell.
*
* Merged
* Tells whether the cell is merged with other cells. Cells may
* occupy other cells space on demand. You may force a cell to
* do so by setting this flag. Merging the cell with 0 in both
* directions, will disable this flag!
*
* CellTooShortX
* When it's True displays ** and/or the red triangle and when the
* mouse is over it, the tooltip displays the full value
* it's true when text size is bigger that cell size
* and when Align is center or left
*
* CellTooShortY
* When it's True when mouseover it, the tooltip displays the full value
* it's true when text size is bigger that cell height
