With deepReduce(), when a simplifiaction was interrupted, expression could
contain Undefined children, which would trigger the assert in
removeUnit(). With reduce(), if a simplification is interrupted, the
entire expression becomes Undefined, which is handled by removeUnits().
Zooming in and out on a graph usually preserves orthonormality. However,
if the window has its bounds close to the limits for the values on the
axes, zooming can change the ratio.
Units derived from kelvin (mK, cK, ...) were handled like Celsius and
Fahrenheit, causing a bug where multiplications such as 2*pi*_cK to
simplify as undef.
Because of the limitations of the floating-point representation, e^x is
null for x <= 710, causing the nextRoot functions to find roots for it.
To prevent this, we looking for places where a function changes sign, we
actually require the function to take two non-null values of different
signs.
This method is used to remove extraneous empty sapce in the middle of
the window for functions that are discontinuous between their points of
interest.
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.
A test in equation_solve relies on the angle unit being set to Degree,
but doesn't actually set it. Changing the angle unit to another one in a
test prior would break this test.

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.

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
function.
