surface: Made some sources EOL style to LF.
surface: Improved debug drawing of aerodynamic tensors for F15.

Now the debug graphics show cuboid with each area corresponding to
the drag.  It's sort of pretty good visualization which tells us
the current aerodynamic tensor settings are a bit too ideal.

This commit also includes experimental TeX formula embedded into
the codes.  Currently there's no way to compile them to mathematical
form other than to copy and paste to a TeX document source.
surface: Tweaked initialization codes to use loops.
surface: Further optimized debug drawing with loops.
surface: Added rudder to controllable surfaces of Aerial.

As always, F15 demonstrates this feature.
