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.

It was a pure virtual method implemented in derived classes
Shared::FunctionGraphController,
Regression::GraphController.
InteractiveCurveViewRange does not need anymore to hold CurveViewCursor
* m_cursor.
