ecf3f2ea0f [poincare] Create a a flag on Expression that is set when the 
approximation encouters a complex value

All approximation methods take the complex format into account.

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)

drawn, pick the labels 1 and numberOfLabels-2 if the real extrema labels
will be cut.

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!

g(5) fails.

ec08f027c0 [poincare] Revert: Use Simplify instead of Reduce II 
To approximate an expression, it is more precise to
approximate its simplified form than its reduced form. Indeed, we want
to minimize the number of nodes in the expression before approximating.
For instance, a/b has fewer nodes than a*b^-1.
