It looks like gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4) thinks it's a good
idea to complain about every single zero-initialized C structure.
This is widely acknowledged as a (rather annoying)

Add a constructor to silence the warning where possible.
For DMCP C structures where this is not possible, well, add ugly code.
With gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4), there is a message about

There was one case where the fall-through was not intentional.

These are two catalogs that behave much like the constants catalog,
and inherit most of the code.
The equations library is intended to store standard equations.
The library is for standard objects and various useful objects or

Both can be organized by topics.

Make sure that we capture consistent pixmaps, which we can do on the
RPL thread, and only defer the transfer of the pixmap to the main
thread, which is fast.
Additionally, optimize updates by doing a byte-by-byte xor comparison
in order to see which bytes actually changed. This minimizes the cost
on the RPL thread to update the pixmap.
This makes it possible to have a much better screen behaviour for the
`CBench` benchmark, where it updates it regularly on the screen while
not slowing things down too much.

When the argument describing the variable is a text, interpret that as
a file path on the disk. By default, data is stored in in a directory
named `data`, which will be created if necessary. For example, you can
use `3 "foo.48s" STO` to store the value `3` in a file named
`data/foo.48s` on disk.
How the file is stored depends on the extension given to the file:
* For `.txt` files, the object is stored as text
* For `.48s` files, the object is stored as DB48X source code
* For `.48b` files, the object is stored in binary format
* For `.csv` files, the object is stored in comma-separated format.
The binary format used for `.48b` includes a 4-byte magic number
identifying a DB48X format, and a 4-byte checksum used to ensure
binary compatibility between the firmware and the disk format.
At least during early days of development (prior to 1.0), it is quite
unlikely that the binary format for one version of the firmware would
be readable or writable by another version. If you need to recover
data from another version, you need to install that version and save
the object again in `.48s` (text) format.
