In Calculation, keeping the BACK key pressed can lead to iffy
simplifications and uninitialized expressions beign passed to
ShouldDisplayAdditionalOutputs and SetAdditionalExpressions methods.

Additional results are proposed for all units combinations that include
a non-base unit, in addition to units with special results.

When tuning the representative without tuning the prefix, the prefix
would not be reset to its default value, causing a problem for masses,
whose base prefix depend on the representative (k for grams, none for
the rest).
Fixes a crash when typing sqrt(_N) with country set to US.

In metric, sqrt(N) would be simplified to _N_kg^-0.5_m^-0.5_s instead of
_kg^0.5_m^0.5_s^-1.
We solve this issue by preventing simplification using derived units
in presence of rational exponents.

In Trigonometry::shallowReduceInverseFunction, the reduction of
atan(1/x) used the hard value of pi instead of its equivalent in the
selected angle unit.
This fixes a bug causing atan(1/tan(40°)) to be equal to π/2-40 instead
of 50.

Units with the same name in all available languages have been moved to
the new file toolbox.universal.i18n.

After parsing the .i18n files, compare the messages and raise an error
if some of them could be factored into a universal file.

Do not display the regular view when the main view takes up all the

This fixes a bug causing the language menu to be briefly visible before
the logo on start-up.

Cache did not check that the step was the same before panning, causing
old values to remains cached.
e.g. :
- Type f(x) = x, and plot it.
- Go to Axes, and set Xmax = 0.
- Confirm

Temperatures can be converted to and from degree Celsius and Fahrenheit.
When used in non-trivial calculations, they are always reduced to undef,
as the rules for manipulating relative scales are not well defined.

Fix a bug preventing the cursor from moving to other curves using UP and
DOWN when the y value was undef.
To reproduce :
- In Graph, define f(x) = 1 and g(x) = ln(x), then draw the curves
- Press DOWN to select g
- Press LEFT until g is not defined anymore
--> Pressing UP or DOWN won't allow you to select f

Fixed issues due to copy/paste of empty formulas. When pasted, empty
formulas are now recognized by the parser and apear with the
correct layout
Without this process, copying an empty integral then pasting it gives :
int((), x, (), ()) instead of drawing an empty integral

When a formula is pasted in a script or in the shell, some symbols are
replaced by their equivalent in python :
x turns into *
^ turns into **
√ turns into sqrt

The solutions of equations that need numerical approximations to be
solved are now computed base on the undeveloped equation (instead of
fully the expended one used to identify polynomials)
This allow (x-10)^7=0 to yield x=10 as result (9.95 before)

Mixed fractions for negative rational numbers are now computed as the
opposite of their opposite's mixed fraction, as is conventionnal.
ex : -9/5 is now decomposed as -1-4/5 instead of -2+1/5

Sequences can now be defined using specific terms form other sequences :
Un = n
Vn = u(3)
Initial values can also depend on other sequences.
Should there be a circular dependency, the sequences concerned will
display "undef" as value
