When the line width is set to 0, we were incorrectly taking
`(width-1)/2` for the negative offset, resulting in a huge box being
drawn instead of a thin line.
Arguably, a line width of 0 should maybe not be drawn at all?
But this makes it more likely that someone will run the test, see a
blank screen and think this is buggy.

Compiled local variables is a rather obscure feature with a weird
syntax. It is documented on page 1-10 of the HP50G advanced reference
manual as follows:
Global variables use up memory, and local variables can’t be used
outside of the program they were created in. Compiled local
variables bridge the gap between these two variable types. To
programs, compiled local variables look like global variables, but
to the calculator they act like local variables. This means you can
create a compiled local variable in a local variable structure, use
it in any other program that is called within that structure, and
when the program finishes, the variable is gone.
Compiled local variables have a special naming convention: they must
begin with a `←`. For example,
« → ←y 'IFTE(←y<0,BELOW,ABOVE)' »
The variable `←y` is a compiled local variable that can be used in
the two programs `BELOW` and `ABOVE`.
There does not seem to be any mention of the feature in the HP48 user
manual.

For equations, it's often the case that they render horizontally.
Have `Show` automatically switch between horizontal and vertical mode.
The `MaxW` value has been increased to 1280 to match this new
behaviour, and the `MaxH` value has been decreased to 1280 because a
1280x1280 bitmap is already about 204K, so it is unlikely to work well
in the DM32 memory constraints.

For all commands, put the arity check in the top-level evaluator.
This factors out all that code in a single (source-code) location.
This also makes it possible to use arity reliably during parsing of
expressions, and fixes a number of cases where it wqas set wrong, like
for the `det` command and many others.
Finally, it fixes missing calls to `rt.args` for a number of commands,
while explicitly removing it (`nargs < 0`) for a few cases where it
was harful, like `LastArgs` or `Undo`.

Add "real" n-ary functions for `sum` and `product`.
Note that the HP50G does symbolic pre-computation for sums, with the
interesting side effect that it may give "strange" results for empty
sums. For example, `I 10 1 'I^3' Σ` gives `-2024`, which is a bit
suprising.
The rationale, I believe, is that `I A B 'I^3' Σ` is first simplified
as `'(B^2+2*B^3+B^4-A^2+2*A^3-A^4)/4'`, which gives the negative
result when `A>B`.
This behaviour is not replicated in DB48X, which follows the HP48
model, where a sum between 10 and 1 returns 0, not a negative value.
