This will allow us to export and parse a variable that contains directories and
subdirectories.

Two representations for fractions, one for small value of numerator and
denominator, one when both values are larger.

Having a sized type for bignum is more efficient both at runtime and in terms of
memory usage:
- At runtime, we don't need all the 7-bit masking and modulo-7 arithmetic
- In terms of memory, there is a cross-over at 63 bits, which is almost exactly
where it becomes uninteresting to do in-CPU arithmetic

Reset the vertical font positions in the table to what they were initially,
add -y option to ttf2font to perform the adjustment in code.
This preserves the relative positions of lowercase 'a' and 'g' much better,
and allows the guides in the font editor to show at the right position.

Get rid of the AutoComplete pseudo-command, so that we display the name of

When using the command line and the variables menu, have the function keys
insert `Store` and `Recall` statements for a given variable depending on what is
being typed.

The superscript `-` is used for things like `cos⁻¹`.
It showed in menus, but not on the command-line.
The triangle will be used for directories.

The VariablesMenu lists the variables in the current directory.
Clicking on a function directly executes the associated variable
With shift, the variable contents is recalled
With xshift, a new value is stored in the variable

It is unclear if ID_eval and ID_EVAL should be any different.
For now, assume that ID_eval will enforce additional checks.

Connect functions like sin, cos, tan, log, etc.
The bad news is that the bid128 functions take _a lot_ of space.
I thought that all of the Intel decimal floating point library was put in the
QSPI, but apparently, only some tables are. The total of the Intel
floating-point code is roughly 1.49M, the code in the calculator roughly 423K.
The code is rather on the large-ish side, with some large chunks of code that
are really hard to explain, like bid128_pow taking a whopping 42K, which is over
5% of my total memory budget (unless I want to take over the QSPI).
