4869383263 [poincare/zoom] Better handling of single points of interest 
Functions with a single point of inerest used to be drawn on a tiny
interval around this point.
Now, an orthonormal window is built around the point of interest, giving
a much nicer view.

291b400595 [poincare/zoom] Ignore imprecise float value 
When looking for extrema in a function, we need to discard results where
the function growth rate is smaller than the precision of the float type
itself : these results are likely to be too noisy, and can cause false
positives.
e.g. : The sqrt(x^2+1)-x function

adf28345b1 [poincare/zoom] Reduce zoom artifact 
Do not use the bounds of the interval when computing a refined range.
As the bounds are often integers, the zoom would give strange result on
some non-continuous functions (e.g. f(x) = x!).

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.
