It's not necessary for assigning `__seg` pointers to `far` ones, which
might even remove the <dos.h> dependency in some translation units.

Oh, wait. Due to ridiculously unlucky alignment, we can't actually
approach TH03's OP.EXE from the top of code segment 2… without
covering way too many functions at once, that is.
At least TH02 works out with "just" three functions at once. *If* we
add seg2 back to OP.EXE, where we previously needed to delete it… 😵

Whew, time to look at every `int` variable we ever declared! The best
moment to do this would have been a year ago, but well, better late
than never. No need to communicate that in comments anymore.
These shouldn't be used for widths, heights, or sprite-space
coordinates. Maybe we'll cover that another time, this commit is
already large enough.
