When using the Navigate menu on graphs, the grid units are computed
using the normal graph's range, so that the units won't change.

When entering the Navigate menu, a portion of the Y axis is memoized to

However, this portion was not modified when zooming, causing some

Empty columns are automatically removed ; the same is now done to empty
rows.

Empty columns and rows are only removed automatically when they are the
last row/column. This way, the user can edit a median row/column without
the matrix collapsing.

Allow removing empty columns with backspace, the same way one can remove

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!).

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

Now, an orthonormal window is built around the point of interest, giving

Remove the "sto" from the x^y/sto->/F key, and add the % symbol to the
Backspace key.

As a consequence, log(x,0) = ln(x)/ln(0) = undef

When three functions or more, the third function and later don't use
caching. But it is still possible for them to have been linked to a
cache (for instance if previous functions had been deactivated earlier).
To avoid a function tapping into another function's cache, we reset the
cache.

e.g. Define 3 functions f(x)=1, g(x)=2, h(x)=3, and deactivate f.
     Draw the graph, come back, reactivate f, then draw again.
---> The space between y=2 and y=3 will be filled with the color of h,
as h "remembers" using cache n°2, wich currently contains the values of
function g.

When a function that had previously been cached is deactivated, its
cache can be used by another function. When the function is reactivated,
if it tries to reuse its previous cache, it will be filled with values
from another function, and will not be cleared. By detaching the cache
of a function that becomes inactive, we ensure that the next time this
function is cached, the chache will be cleared.

e.g. Define to functions f(x)=x, g(x)=-x, draw them both.
     Deactivate f, the redraw the graph
     Reactivate f, the draw again

The logarithm function is undefined for negative numbers, but its
derivative, the inverse function, is defined everywhere. We thus need to
virtually limit the domain of definition of the derivative.

a variable in radians. A multiplicative constant must be added when
another unit is used.

The general formula for deriving a power makes use of the logarithm,
which often disappears at simplification. However, replacing the symbol
before simplifying can lead to applying an invalid argument to the
logarithm, making the whole expression invalid.

e.g. diff(1/x,x,-2)
     If x is replaced by -2 before reducing the power derivative, ln(-2)
will reduce to Unreal, as will the rest of the expression.

Derivate the numbers Undefined, Unreal, Infinity symbolically :
  Undefined -> Undefined
  Unreal    -> Unreal
  Infinity  -> Undefined

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.

When computing the automatic zoom, if the X axis has integer bounds
(most likely because the range has been built to be orthonormal), do not
add margins to the X axis, so that it keeps user friendly values.

When building an orthonormal range for the automatic zoom, we provide a
ratio for the screen without the margins. This way, adding the margins
will make the graph orthonormal, and the banner cannot cover the

Evaluating a function containing a sequence, an integral or a
derivative, is time consuming. Computing a range requires a plethora of
evaluations, as such ranges for these functions cannot be evaluated in a
timely fashion.

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.
