Per comment from kreator, some Apple systems now ship without a working
print screen key. It makes no sense to provide print screen support
bound to a key which does not exist. Add `screenshot=none` and activate
it on OS X to remove the unreachable screenshot support.
If the player commits suicide in Descent 2, Point_segs[-2] is accessed
because aip->hide_index = -1, aip->path_length = 0. As a spot fix,
check for underflow and skip the access if it would be out of bounds.
Prior versions of Descent had a bug that specifying `briefing=` did not
inhibit a briefing. Instead the directive was completely ignored. The
engine would then use the auto-detected briefing if one was found. This
quirk was eliminated during refactoring of the mission parsing code.
Unfortunately, some published missions relied on this bug: they ship a
briefing, but their mission file explicitly states that there is no
briefing. Players expect the briefing to play despite the mission
stating that there is none.
Reorder the logic to restore the bug that `briefing=` is ignored.

When using variadic forwarding constructors
(`sconf_cxx11_inherit_constructor=force-failure`) instead of inheriting
constructors, some ternary expressions become ambiguous due to the
inability to forward the `explicit` modifier from the base class
constructor to the derived class. Add explicit type overrides to
disambiguate these expressions to the result that the compiler would
have picked on its own when using inheriting constructors.
Ill-formed levels can provoke this exception. Downgrade the error from
a fatal exception to a CON_URGENT message.
Increase the array size to 32 from D1:7, D2:20, since each element is
only an int.
Switch from an assertion on bitmask overflow to a CON_URGENT warning.

Many gauge functions take the same parameters, and pass those parameters
on to child functions in turn. Bundle common parameters into a few
standard structures, so that adding new context does not need to involve
every function in the chain for every new context value.
If user_settings.sharepath is configured to be blank in SConstruct, omit
the C preprocessor macro SHAREPATH instead of defining it to expand to
an empty string. Adjust the C++ code that uses the macro SHAREPATH to
handle its absence:
- Clearer output in help text
- Skip adding blank SHAREPATH to the PhysFS search path.
As a nice side effect, this enables SHAREPATH on Windows, which could be
helpful for builds shipped with an installer that places game files in a
well-known location (such as "C:\Games\Descent"). Previously,
!defined(__unix__) systems did not add SHAREPATH to the PhysFS search
path, even when one was defined.
digi_play_sample_once is supposed to cancel prior instances of the
sound, but that functionality was lost in
21082c6db2. As a result, the sound can be
stacked up to the limit of the engine. Even when the functionality
existed, its implementation was wrong.
- Change these sounds to be attached to the player generating them.
- Pass the cancellation flag to other players when sending a sound.
- Send the full value of `volume`, rather than truncating it.
- Implement cancellation by killing and restarting the earlier version of a cancelled sound.
- Delete an ugly hack that prevented the patched logic from ever running.
- Fix an ancient quirk in digi_mixer that caused it to report all sounds as not playing, which then caused digi_sync_sounds to instantly cancel the new sound.

Define global copies of the user's chosen host address, host port, and
local port. When these are non-empty, prefer them to the values from
-udp_hostaddr, -udp_hostport, and -udp_myport. When the user attempts a
connection, update the global copies from the user's data. If the user
abandons the connect dialog, do not update the globals.

Slide left/right: A/D
Slide up/down: C/X
Accelerate/reverse: W/S
Afterburner (D2 only): Left-Shift
This produces the more FPS-typical WASD layout for
forward/left/back/right movement, and maps the crouch/stand bindings to
slide up/down. This ticket sat for longer than it should have (though
it never missed a release). Several competing designs were suggested,
but only one could be made active. After consideration, I used my own
bindings on the basis that, while some other bindings may be better,
every other configuration repurposed a classic weapons-fire key to
movement. Returning players who get the "new defaults" on a newly
created pilot profile might be very surprised by having their fire keys
move. Since these are only defaults, and can be rebound by the player
with a few minutes work, these defaults do not need to be perfect. They
just need to be an improvement over original Descent.
Delete unexpand-cpp-kconfig-key.py. It will likely never be needed, and

Various files included compiler-static_assert.h to use the compatibility
macros for compilers that lacked a working C++11 static_assert.
However, some source files used static_assert without this inclusion,
and no one ever reported problems. From this, assume that no one uses a
compiler which lacks C++11 static_assert. Remove the inclusions that
were only for the compatibility macro. Keep the inclusions that use the
assert_equal helper.
Materialization centers ("Matcens") have a governor to prevent
overrunning the level in robots. However, due to a logic ordering
error, multiplayer games failed to record how many robots had been
destroyed, so for the purpose of detecting whether there were currently
"too many" robots in play, the game pretended that no robots had ever
been destroyed. Therefore, once enough robots had been created to reach
the "too many" threshold, matcens stopped generating robots, regardless
of how efficiently the player(s) had been destroying robots.

If no character matches the typed character, the loop should exit when
`lb->citem == cc`, which should happen after every entry is visited
once. However, if no item is selected, `lb->citem == -1`, and `cc` is
never `-1`, so the exit path never triggers. Rewrite the loop to be
bounded by number of steps, rather than bounded by returning to a
particular offset. This also protects against undefined behavior if the
menu had zero elements.
[Kp: as discussed in pull #377
<https://github.com/dxx-rebirth/dxx-rebirth/pull/377>, the previous
implementation requested a parameter combination not permitted by
OpenGL. At best, this error was silently ignored. Fix the error by
falling through to a switch case statement that sets valid parameters.]
Users with disabled VSync might not expect any forced waiting on the GPU,
and the GL sync methods were intented to fix issues with VSync only,
so the new heuristic for SYNC_GL_AUTO is to enable GL sync only if
VSync is enabled, too.
Users can still request to use a specific GL sync method via the
-gl_syncmethod switch, independent of the VSync setting.
[Kp: folded `else { if () }` into `else if ()` to avoid moving
`ogl_have_ARB_sync` lines. Original change visible at

Global `Viewer` was copied to local `viewer`, and the local should have

Mako88 requests, as have others in the Rebirth forum, that the FPS
indicator be placed on the right side. Moving to the right side was
quick. Moving it low, handling all the different rendering combinations
(cockpit, statusbar, fullscreen; standard vs alternate; single player vs
multiplayer), and not overlapping anything in any of them was time
consuming.
If anyone wants more changes in this area, the existing modes ought to
be revisited and unified. As is, there are pointless inconsistencies
among the modes, which makes it unnecessarily difficult to position an
element correctly.
