TODO
----
+random.c should not know about set_seed.
+
+Probably should get rid of approx.h. The user really needs to be responsible
+for his own precision.
+
+Use AFM files instead of Groff font files, and include AFMs for our default
+fonts with the distribution.
+
The way that data-in.c and data-out.c deal with strings is wrong. Instead of
the way it's done now, we should make it dynamically allocate a buffer and
return a pointer to it. This is a much safer interface.
See if process_active_file() has wider applicability.
-Looks like there's a potential problem with value labels--we use free_val_lab
-from avl_destroy(), but free_val_lab doesn't decrement the reference count, it
-just frees the label. Check into this sometime soon.
-
Eliminate private data in struct variable through use of pointers.
Fix som_columns().
