gr_init_bitmap can be passed a pointer to uninitialized memory, and
will save that pointer into the bitmap for the underlying memory to be
initialized later. In gcc-11, this triggers a warning because the
`const` qualifier leads gcc to expect that the memory will only be read
(while uninitialized) and not written.

fbd05a1592 changed joy.h to include only fwd-event.h, but not event.h.
event.h included maths.h, which kconfig.h was relying on. Add an
inclusion of maths.h into kconfig.h to define `fix`.
Fixes: fbd05a1592 ("optimize include files (include what you use)")
Enable stereo mode when launched via -gl_stereo option.
GL_STEREO quad buffering may not be available unless OGL layer
supports stereo pixel format descriptors.
Half-height viewport rendering for above/below format.
Half-width viewport rendering for side/by/side formats.
HUD & cockpit elements disabled when stereo views active.
OGL layer used for rendering surfaces, so using left/right viewports absent stereo quad buffers.
Using legacy Descent +/- eye offset method for left/right stereo perspective rendering passes.
These are not necessary for proper compilation, but are included so that
a mismatch between the forward declaration and the definition will be
diagnosed immediately.
Previously, rendering the preferred bomb type could also change it if
the active type was exhausted. This is undesirable, since it depends on
the user to have a HUD mode which causes the bomb type to render.
Switch to only change the active type if the user tries to drop a bomb
while the active type is unavailable. Some call sites already switch
bomb types automatically on depletion. Those sites will still do so.
std::find_if needs common iterator traits. Add the relevant type
definitions to zip_iterator.
Also add them to d_range, to avoid errors when a range is zipped.
After the previous commit, its only purpose is to automatically dismiss
the window after 3 seconds. Users may be surprised by this, and the
automatic dismissal has limited value. Remove it and let the user
remain at the cancel dialog until a decision is made.
Previously, callers chose whether to use a fullscreen background image,
and the newmenu code inferred that callers without a background image
wanted a background box, while those with a background image wanted no
box. Change newmenu_layout to take a parameter specifying the caller's
intent, so that a caller can choose to have any combination of a
background image and a background box.
PHYSFSX_isNewPath retrieves from PhysFS a list of all paths, then
searches them, and frees them at the end. PhysFS can search its own
list without needing the allocations, so delegate the work to it.
Previously, if the background failed to load, the kmatrix window was
immediately aborted. Change the logic so that a failure to load uses a
blank black background, but still shows the kmatrix window.
Once the loop has determined a vertex is used at least twice, there is
no need to count how many more times it is used. Return immediately
after detecting the second use.
- Make it static
- Remove the update of Num_vertices, since the caller reverses that
update.
- Remove the reversal, since it is no longer needed.
- Remove the test and update of Vertices.count, because the caller
always passes a vertex number that makes the test false.
The Miner LVL files are not present in retail Descent 2 data. I know of
no way to obtain them. The code for loading them has been marked as
broken since 2018, and no one reported it. Remove this support to
simplify future work.
This reduces the call depth by one, and eliminates a load of a global
variable that always has the value MULTI_PROTO_UDP. It adds a load of
the address of the empty dispatch object. Overall, this should be an
improvement.
Every user now uses inheritance and a virtual function override. Make
callback_handler pure virtual, delete its body, and then delete the
member variables that existed only for use in that body. Remove the
constructor parameters that initialized those variables, and update all
derived classes accordingly.
The requirement to call send_creation_events from outside the
constructor makes the presence of a helper function convenient. Rename
ui_create_dialog to window_create, and move it to window.h.
For gcc bug #10138 [1], gcc-11 gained a new way to show a
-Wmaybe-uninitialized warning. When an uninitialized array is passed by
`const T *` to a function, gcc-11 assumes the array is an input to the
function, and warns accordingly. This is often useful, but is incorrect
for the Rebirth partial_range code. In this code, the pointer is only
passed so that the eventual exception can print the memory address of
the affected array. The called function does not dereference the
pointer, and so cannot be influenced by any uninitialized values in the
underlying array.
Change the report function to take the array address in a `uintptr_t`,
and cast it back for printing. This silences the gcc-11 warning, while
preserving the previous semantics in the code.

Previously, if SDL_AllocRW failed, then the handle would not be saved
into an SDL_RWops (since that object was not created), but it would also
not be closed immediately.
clang warns if all of:
- type T is deleted by a pointer T*
- T has a non-virtual destructor
- T has a virtual function
- T is not final
Fix the build by making the relevant types T final, since nothing
inherited from them.
Kreeblah reports that clang now warns for powerup.cpp due to a missing
__attribute_format_printf. This was incorrectly dropped in
ffb653c0b8. gcc did not warn, but clang
now warns. Add back the attribute.

Due to ordering constraints, this is not merged into MENU, but is
instead kept as a distinct sub-type that is pointed at by MENU. MENU
sets the window's position based on parsing of the menu definition file,
but the parser expects to store window position data into MENU before
creating the window. If menubar_window were merged into MENU, the
parser would need a temporary, and all callers that create the window
would need to consult that temporary.
All callers request either the menubar or something else, but never
conditionally request one or the other. Split the special handling that
picks a different handler based on which element the caller requested.
Fix potential buffer overflow if `length` (now `length_of_initial_text`)
is less than the `strlen` computed length of text.
Rename variables to clarify usage.
Eliminate the unnecessary use of `strlen`.
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.
