48bf209f48 [apps/curve_view] Fix zero label position
For instance, in Probability app, draw a standard normal law. The zero
was top left of the screen...

5d1ef0f3f0 [apps/sequence] Use first ranks when computing graph range
Put two sequences u(n+1)=u(n) and v(n+1) = v(n), u(100) = 50, v(50) = 8.
Basic settings computed the x range as [0,10] before, now it is
[50,110].

4d1114ef63 [apps/curve_view] Increase numberOfSignificant digits when needed
Labels might be rounded to the same value (for example, in Probability,
draw a normal law with mu = 100000 and sigma = 0.1), in which case we
need to display extremal labels only, with increased number of
significant digits.

c6039423a9 [poincare] When simplifying an expression, also compute the approximation from the reduced
expression to avoid loss of precision.

If an expression is reduced to a ComplexCartesian(a, b), we compute the
approximation from ComplexCartesian(a,b) instead of going through the
potentially complicated expression resulting from beautifying
(sqrt(a^2+b^2)*exp(i*(arctan(b/a) -Pi/2*sign(b)) for example)

8c6ffa6d42 [apps] Fix graph X axis labels that read the same
Scenario: just zoom in in a graph
Fix:
- Do not truncate labels.
- Label size is computed depending on available size and number of
 labels.
- If labels cannot be displayed properly, just display the minimal
and maximal labels!
