Support for ORTHO_VIEWS has been broken since commit
db514a5ded in December 2004.
`git blame HEAD -L872,+4 -- similar/editor/meddraw.cpp`:
```
db514a5ded main/editor/meddraw.c (Bradley Bell 2004-12-19 13:54:27 +0000 872) }
db514a5ded main/editor/meddraw.c (Bradley Bell 2004-12-19 13:54:27 +0000 873) } else
db514a5ded main/editor/meddraw.c (Bradley Bell 2004-12-19 13:54:27 +0000 874) #if ORTHO_VIEWS
db514a5ded main/editor/meddraw.c (Bradley Bell 2004-12-19 13:54:27 +0000 875) else if ( screen_canvas == TopViewBox->canvas )
```
When ORTHO_VIEWS is true, this code expands to `} else else if (...)`; a
double-else is not legal, so the code cannot have been compiled with
ORTHO_VIEWS enabled. All 4 of the relevant lines date to db514a5ded,
which itself is an import of files from the D1X editor.
When joystick support is not present, `event_joystick_get_button` is not
declared in joy.h.

Define separate enum values for rotation data in both the high bits,
where it is usually kept, and the low bits, where it is sometimes used
for math or comparisons.
Define an enum value to represent the composite of the index and the
rotation, since the composite is not suitable for use as an array
subscript. Add helper functions to extract the component pieces.
tmap1 cannot be rotated, so checking for it inside
convert_to_d1_tmap_num is wrong. tmap2 can be rotated, and checking for
it outside convert_to_d1_tmap_num is cleaner.
segment inherits unique_segment, so unique_segment members can be
referenced from an instance of segment. Eventually, segment will be
removed. Adjust references to go through unique_segment to support this
change.

gcc and clang disagree about how to disambiguate when an identifier is
both a typename and a member. Avoid the disagreement by renaming the
member.

Use an enum class to prevent implicit conversion between trigger
behavior flags and other integers. Fix up various resulting breaks,
which look like bugs:
- Descent 2 editor mode could modify trigger::flags, but used
TRIGGER_FLAG_* values, which specify the actions for a Descent 1
trigger when it executes, not the behavior properties for a trigger.
- Adding a trigger set its flags to 0, then cleared all flags except
TRIGGER_ON. Since the flags were just set to 0, the mask operation is
useless. Remove it.
- trigger_turn_all_ON cleared all flags except TRIGGER_ON. This seems
to be completely wrong. Change it to remove
trigger_behavior_flags::disabled. Descent 1 has no (working) support
for disabling triggers, so make trigger_turn_all_ON exclusive to
Descent 2.
- wall_restore_all would enable TRIGGER_ON in both games. Descent 1
never reads TRIGGER_ON. Descent 2 uses this field for trigger
behavior flags, and TRIGGER_ON is not a behavior flag.
- For Descent 1 builds, remove the modification of the field.
- For Descent 2 builds, change it to clear
trigger_behavior_flags::disabled.
The automap code keeps a mostly-private secondary copy of control_info.
The change to reset control_info before the event loop reset the main
copy of control_info for the automap, not the copy that the automap
actually used. Fix this by passing the desired control_info to relevant
functions instead of always using the global variable Controls.
