This method of InteractiveCurveViewRangeDelegate was only used to
compute the Y range when Yauto was on.

The new zoom implemented for ContinuousFunction is now factorized inside
Function to benefit the Sequence class. The same things is done to code
added to Graph::GraphController, which is moved into
FunctionGraphController.
This removes the reimplementation of several methods, most notably
computeYRange, as the implementation for function is general enough to
work on sequences.

Additional checks have been added to ensure that the first move of the
cursor from the center of the graph would not cause the window to pan up
or down.

Initial zoom for displaying curves is computed according to the
following rules :
- For polar and parametric curves, the algorithm has not changed.
Vertical and horizontal ranges are chosen in order to display the
full curve with orthonormal graduations.
- For cartesian curves, the horizontal range is chosen in order to
display all points of interest (roots, extrema, asymptotes...).
The vertical range is fitted to be able to display those points, but
also cuts out points outside of the function's order of magnitude.
