89c50509d8 [shared] InteractiveCurveViewRange::isOrthonormal 
The old method isOrthonormal has been split into two :
  - shouldBeNormalized tests whether the range is close enough to a
    normal range
  - isOrthonormal tests whether the range is strictly orthonormal, but
    takes into account imprecisions of floating-point arithmetic

7322751453 [regression] Compute Y range for curve 
Regression's automatic Y range used to rely on the Yauto feature. Since
it has been removed, it is now done in Store::setDefault.

84768472bd Explicit std::min/max template usage 
This is unfortunately required in several cases:
 - Sometimes when we use either float and double (this should be changed)
 - Because KDCoordinate is not an int, so any arithmemtic promotes it to
an int
 - Because we mix pointer differences and ints
