This preserves virtually all game information, including active fire. The saved game 'gamesave.sge' can also be loaded with File->Restore Game State. The level can still be saved as usual (but it warns the user if there's an unsaved game state). This functionality may be useful for testing (or cheating! ;) )
Various points in the game code call `hide_menus()`, then later use
`show_menus()` to reverse the effect. If the forcibly hidden window is
deleted before `show_menus()` is called, the attempt to show it would
write to freed memory. Add a hook to forget those windows when they are
deleted, so that `show_menus()` does not try to make them visible later.
Commit 1c8ad24 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to
-Wunused-but-set-variable.
Fixes: 1c8ad24da3 ("Check for window_event_result::deleted for ui_get_filename polling loop")
Commit 917f079 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to

This reverts commit 3c20c24ac0.
Rebirth no longer contains the Descent memory manager, but Rebirth still
has many traces of the paging support used in the DOS version. One of
the unfortunate and subtle traces of this support is that it allocates a
contiguous buffer for game data and loads many of the games bitmaps into
that buffer. The buffer is large enough for most workloads, but not
all. When the buffer is too small, it is discarded by
piggy_bitmap_page_out_all and rebuilt piecemeal to contain only what it
needs. Fixing this would be nice, but the memory ownership rules are
messy. The performance consequences of the legacy approach are not
sufficient to justify the effort to fix this properly. Instead, revert
to the legacy design.
To recognize getaddrinfo as supported, require that the AI_* flags
passed to it be usable:
- AI_NUMERICSERV must be defined as a number or be undefined
- If ipv6=1, then AI_V4MAPPED and AI_ALL must be defined as numbers
When getaddrinfo is used, raise _WIN32_WINNT from 0x501 to 0x600.
Otherwise, lower it to 0x500.
Constructing valptridx::basic_ptr with a known-invalid magic index does
not require an array. Simplify the static_assert to reject uses of
factory functions with known-invalid magic index values. Fix the two
sites that fail with the stricter static_assert.
When File->'Play in 320x200' is chosen, use StartNewGame(Current_level_num). For now use create_new_mission and Current_level_num = 1 every time. Also remove the now redundant hacks GM_EDITOR and editor_reset_stuff_on_level.
The functions med-mark-start and med-mark-end don't exist - that's fine, still read the rest of the menus, so it can actually properly 'hide' the help menu after it's clicked on.
If a game was playing, continue playing. If it was in the main menu, return to the main menu. (If all files are put in place the editor can load again.)
As the UI_DIALOG client is now responsible for freeing all gadgets (via unique_ptr's), this function now causes issues where it attempts to access freed gadgets (resulting in std::runtime_error("unknown gadget kind") exception when closing the AI Properties dialog on my Macbook, for example). Removing the offending function fixes the issue.
Move the main part of obj_link into obj_link_unchecked. Implement
obj_link as sanity check assertions followed by a call to
obj_link_unchecked. Remove caller-side writes that were present solely
to bypass the assertions, since the assertions can now be bypassed by
calling obj_link_unchecked directly.
Split ogl_get_verinfo() into ogl_tune_for_current() and
ogl_extensions_init(), and consolidate all the OpenGL extension handling
into ogl_extensions.cpp. Unify the code paths for texture anisotropy and
GPU synchronization for OpenGL and OpenGL ES.
Currently, our renderer only uses GLES 1.0, so no real world implementation
will support sync objects for such an old context, but the logic is valid,
and this way, the GLES specific code paths are reduced.
This patch also fixes an issue where the old ogl_get_verinfo() did modify
the texture filtering mode if no anisotropic filter was available. This
was some leftover from the time when the anisotropic filter was a just
a specific CGameConfig.TexFilt mode, and not a separate, orthogonal setting
CGameCfg.TexAnisotropy that it is now.
The segiter code used objptridx because end is signalled by object_none,
and vobjptridx does not allow object_none. However, the compiler
produces better code if segment_object_range_t returns vobjptridx and
future cleanups are easier if iterating objects_in yields vobjptridx
objects. Add a special-case override of the normal checking rules, move
the required checks into segiter, and then let segiter break the rules
normally enforced by valptridx. Add a comment explaining that this
permits unsafe coding and should be done only with a clear understanding
of the responsibilities it brings.
One caller uses fuelcen_activate when segp->special != station_type.
Every other caller passes the type that was already on the segment.
Move the assignment into the one caller that needs it, then remove the
argument.
Add 'track' method to dcx::window, which takes a bool and will set it to 'false' when the window closes. Use for newmenu_do2 and simpler newmenu_do's, since there's the possibility of another window without its own polling loop opening on top - meaning window_event_result::deleted would be returned for that window, not the one we're polling on.
This will allow checking for window_event_result::deleted, instead of relying on window_exists, which could return a false positive if a new window was allocated with the same pointer value as the deleted one.
In particular, window_event_result::deleted so the event system doesn't have to rely on the somewhat problematic window_exists. If a gadget is manipulated, it still returns at least window_event_result::handled so all the other gadgets in all the other windows don't have to be checked (that weren't already checked).
This will be used to inform the event system in future, in removing calls to window_exists. This applies to if the handler returns a window_event_result::close (which is and should be instead of the handler calling window_close itself, at least in most cases).
Make the listbox handlers and all sub-handlers (when_selected callbacks) return a window_event_result. Makes code more readable and removes one use of window_close, making it easier to inform event system if a window closes in future.
The only caller for get_multi_endlevel_poll1 was DoEndLevelScoreGlitz,
which only called it on an unreachable path. That path is now gone, so
remove get_multi_endlevel_poll1.

Rename symbol WORDS_NEED_ALIGNMENT to DXX_WORDS_NEED_ALIGNMENT to show that it is a DXX
symbol, not one inherited from a library.
This is a mostly automated transform, but the changes to SConstruct were
manual.

Allow dcx::UI_DIALOG struct to be subclassed step 3. This step adds the destructor and makes sure the dialog is only deleted within the main dialog handler if the specific handler didn't return window_event_result::deleted.
Replace delete dcx::window kludge with a better solution: instead of requiring every handler to delete the window, add a window_event_result::deleted, which gets returned if the window was deleted by the handler, so window_close knows not to attempt to delete it again.
Allow dcx::UI_DIALOG struct to be subclassed step 1. This step renames and reconfigures untyped_ui_dialog_create in dialog.cpp to be the main constructor. Also adds a template constructor that allows an event handler that takes a subclass of UI_DIALOG.
Allow dcx::window struct to be subclassed step 3. This step adds the window destructor and both requires and implements the window to be deleted by the event handler/client in all cases.
Allow dcx::window struct to be subclassed step 2. This step renames and reconfigures window_create in window.cpp to be the main constructor. Also add a template constructor that allows an event handler that takes a subclass of window.
Allow dcx::window struct to be subclassed step 1. This step moves the definition for the window struct into window.h, keeping all member variables private and declaring the window related functions as 'friends'. This avoids changes to source files that use the window struct at this stage. Also moving some of the simpler functions in window.cpp into the struct definition to inline them. I would prefer to use class methods, so changing some of these to class methods as well.
