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.

When choosing a language and then pressing back from the country menu to
get back to the language menu, the previously selected language remains
selected.

Crashed because the global context was not checking if the sequence was
badly referencing itself

char buffers m_distribution and m_calculation had too weak an alignment,

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

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
etc

When selecting a country, the table would be cropped by the text, with
no separator between the white of the cropped cell and the background
color.

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)

The Equal sign now triggers a syntax error in all apps but Solver. This
make its behaviour symmetrical with that of < and >.

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

The new zoom implemented for ContinuousFunction is now factorized inside
Function to benefit the Sequence class. The same things is done to code
added to Graph::GraphController, which is moved into
FunctionGraphController.
This removes the reimplementation of several methods, most notably
computeYRange, as the implementation for function is general enough to
work on sequences.

The auto zoom did not display the X axis when drawing positive curves
with roots, such as sqrt(x).

Additional checks have been added to ensure that the first move of the
cursor from the center of the graph would not cause the window to pan up
or down.

Initial zoom for displaying curves is computed according to the
following rules :
- For polar and parametric curves, the algorithm has not changed.
Vertical and horizontal ranges are chosen in order to display the
full curve with orthonormal graduations.
- For cartesian curves, the horizontal range is chosen in order to
display all points of interest (roots, extrema, asymptotes...).
The vertical range is fitted to be able to display those points, but
also cuts out points outside of the function's order of magnitude.

Pressing OK or EXE with the brightness setting selected would cause a

poincareCircuitBreaker requires the Back key to be pressed for at least
50 ms before interrupting a computation.
This is effectively invisible for the user, but fixes a bug in
Calculation :
- When leaving the additional results for a result using units by
pressing the Back key, a reduction preceding a call to removeUnits
would be interrupted, causing an undefined behaviour.

After choosing a language at onboarding, the country menu now has a
specific country selected by default (Spain for Spanish, Italy for
Italian...)
Default countries are specified in apps/language_preferences.csv

1. Information about a unit's dimension now uses inheritance.
_m is an instance of DistanceAlias, which is derived from Alias.
A UnitNode now keeps a pointer to an Alias and one to a Prefix.
All aliases are still defined as constexpr.
This cleans up a lot of the code used namely for computing the
additional outputs in Calculation.
2. Instead of being defined with a string, each unit is described by its
ratio with the base SI unit (ex: _L is 0.001 instead of "0.001_m^3").
This greatly speeds up the calculations using units, as the algorithm
to find the best unit used to parse the definition.

Instead of relying on the order in which the apps are passed at compile
time, the look of the Home app is defined in a config file, and depends
on the country chosen.
