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.

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.

Do not display the regular view when the main view takes up all the
frame.
This fixes a bug causing the language menu to be briefly visible before
the logo on start-up.

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

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
etc

When selecting a country, the table would be cropped by the text, with

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)

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

The Equal sign now triggers a syntax error in all apps but Solver. This

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

In UnitConvert::shallowBeautify, an orphan expression would be reduced
without reaffecting the reduction's result. The reduction not being
taken into account would cause problem when handling undef values.

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).
