+** The routines for moving the physical cursor and scrolling:
+**
+** void _nc_mvcur_init(void)
+**
+** void _nc_mvcur_resume(void)
+**
+** int mvcur(int old_y, int old_x, int new_y, int new_x)
+**
+** void _nc_mvcur_wrap(void)
+**
+** Comparisons with older movement optimizers:
+** SVr3 curses mvcur() can't use cursor_to_ll or auto_left_margin.
+** 4.4BSD curses can't use cuu/cud/cuf/cub/hpa/vpa/tab/cbt for local
+** motions. It doesn't use tactics based on auto_left_margin. Weirdly
+** enough, it doesn't use its own hardware-scrolling routine to scroll up
+** destination lines for out-of-bounds addresses!
+** old ncurses optimizer: less accurate cost computations (in fact,
+** it was broken and had to be commented out!).
+**
+** Compile with -DMAIN to build an interactive tester/timer for the movement
+** optimizer. You can use it to investigate the optimizer's behavior.
+** You can also use it for tuning the formulas used to determine whether
+** or not full optimization is attempted.
+**
+** This code has a nasty tendency to find bugs in terminfo entries, because it
+** exercises the non-cup movement capabilities heavily. If you think you've
+** found a bug, try deleting subsets of the following capabilities (arranged
+** in decreasing order of suspiciousness): it, tab, cbt, hpa, vpa, cuu, cud,
+** cuf, cub, cuu1, cud1, cuf1, cub1. It may be that one or more are wrong.
+**
+** Note: you should expect this code to look like a resource hog in a profile.
+** That's because it does a lot of I/O, through the tputs() calls. The I/O
+** cost swamps the computation overhead (and as machines get faster, this
+** will become even more true). Comments in the test exerciser at the end
+** go into detail about tuning and how you can gauge the optimizer's
+** effectiveness.
