Some of the under-the-hood connection values are offset by an arbitrary amount. This could be because of a graphical connection editor allowing a shift in the strip destination pointer, as well as the standard alignment value. There is no visible difference, so it can be confusing when two unique sets of values can produce the same result.
Reversing this invisible offset was a major sticking point back when connections were dumped, but it was straightforward this time around. Much thanks to huderlem for articulating this quirk in pokered's connection macros.
This should make map headers much easier to edit than before.
Rather than occasionally being able to reuse blockdata semantically,
create a label for each map and attach it to some blockdata include.
This improves readability and reduces overhead when adding new maps.
The macro argument length bug doesn't seem to crop up here...
It looks like it only happens when an argument is over 16 characters
long and references a symbol that exists before the macro is invoked.
