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.

ff77b46276 [poincare] Power::shallowReduce. Fix bug: I complex should always be 
shallowReduced as it turns into ComplexCartesian(0,1) if the reduction
target is the User and stays Constant(I) otherwise.

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)

7d9c49919c [poincare] simplifyForComplexFormat: before extracting 
ComplexCartesian/ComplexPolar, deepReduce instead of simplify to avoid
generating uselessly big trees. To make it work, implement shortcuts for
Power::complexCartesian and Power::complexPolar to return nice cartesian
expression when the power index is -1, 1/2 or -1/2

2f8ede54f2 [poincare] The sign function was used to decide wether an expression was 
of form -x. However, ln(0.3) has a negative sign but is not of form -x.
This commit fixes the misuse of ExpressionNode::Sign::negative.
For example, we do not turn sin(tan(9)) in -sin(-tan(9)) or
arcsin(sin(12)) in -arcsin(-sin(12) because tan(9)<0 and sin(12)<0

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!

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.
