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!

f62249c8ac [poincare] Try to reduce the number of digits in print float 
We did not take into account the zeros ending the mantissa when
computing a smaller required length.

f470a99081 [poincare] Multiplications are collapsed in fractions 
For instance, typing 3*2 the '/' creates the fraction (3*2)/
Before, it would only divide the '2'

f6a5759a16 [poincare] Fix the replacement of unknowns in the storage 
In the Graph app, define f(x) = cos(x) and g(x)=diff(f(x),x,x).
The graph and table are perfectly computed, but in the Calculation apps,
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.
