072fdda6b8 [poincare/zoom] Redraft search of orthonormal range 
To find the optimal range with a specified ratio, we compute the values
of the function on a default range, then center the Y axis to display
the maximum number of points of the function.

bd302bb67b [poincare/unreal] Type in derivate method 
Unreal's derivate method returns true, to signify that it is unchanged
by the derivation operation. This implementation mostly exists for
documentation, as an Unreal derivand will be handled by the
defaultShallowReduce method.

ca9cb63909 [poincare/zoom] Reduce the step for searching points of interest 
The algorithm to search for points of interest will miss some. We reduce
the step to make it more precise, so that tan(x) and tan(x-90) have the
same profile.

5df60e946a [poincare] shallowBeautify can modify the reduction context 
UnitConvert must set UnitConversion to None, otherwise the unit asked
for in the conversion might get changed after being properly set in
UnitConvert::shallowBeautify.

d789e8da97 [poincare] In Multiplication::shallowBeautify, when extracting the unit, 
reduce without changing the unit in order to extract the right unit.

This fixes the following bug: simplify "πππ23*_cK"
