The main exits are initiated from code that cannot filter this back to D_DoomMain easily so the exception is the only way to get there.
The 3 main points of exit are:
* quit/exit CCMD
* quitting the menu through ST_Endoom
* receiving a quit message on the main window.
These ones were particularly bad examples of misusing the exit handlers by temporarily installing one themselves and then calling exit to clean stuff up.
Now they just return an error code to D_DoomMain to perform a regular exit.
The main catch is now in D_DoomMain, only calling platform specific functions to handle the output for the error.
As a nice side effect, -norun can now be done without an exception, just by exiting D_DoomMain with a special exit code.
Now there is only one single entry point for both, instead of previously 2 entry and 4 exit points.
This also eliminates the explicit shutdown of ZMusic. Timidity++'s two buffers have been put in containers that self-destruct on shutdown and calling dumb_exit is not necessary because the only feature requiring it is not used by any code in the music library.
Instead of trying a homegrown way to avoid recursive exceptions, let's do it with the defined procedure C++ has for this case: call std::terminate.
This allowed removing some old hackery inherited from Boom and will now hopefully allow sanitizing the exit procedure to the point that it can be done without depending on exit handlers.
The only difference here were the size values on Windows but for this initial call they have been useless for a long time. When this code was written the console buffer still had a fixed width that needed to be set before adding any text.
Mainly done to isolate the calls that actually manipulate the global frame buffer.
V_Init alsoi initialized some palette data, which was moved to V_InitPalette and did something entirely different when running a restart as opposed to an initial start.
This was done for two reasons:
1. It forces loading of zd_extra.pk3 for the stock IWADs, eliminating a certain kind of user error.
2. It removes the stock IWAD definitions for custom games that distribute the engine along with their data, so that it doesn't pick up on Steam and GOG installations and shows an inappropriate IWAD picker.
The episode titles required a workaround because the CQ3 episodes do not contain names in text form: If this is the case, the patch name will be used as a string table identifier to get a matching text for localization.
Some reorganization to avoid code duplication plus making the log screen capable of using the generic font. This also means that the popup for the log in Strife's status bar will be disabled when in generic mode - this popup with its special font would be a bit problematic.
There are two options here - one only disables the vertical thrust and the other goes back fully to the original non-z-aware code.
Both options are settable through MAPINFO.
For the compatibility presets, the normal ones only disable the vertical thrust, the strict ones force use of the old code entirely.
* re-added screen blends for images from the hardware renderer.
* moved all postprocessing of the image out of the renderers.
* cleaned out a large piece of cruft for handling the palette in the frame buffer class. This was all a remnant of the old paletted backend that no longer exists. Nowadays the screen blend is just a postprocessing effect drawn over the 3D screen, there is no need to maintain any of it as global state anymore.
* since the engine doesn't produce paletted screenshots anymore there is no need to have handling for it in the generation code. This depended on otherwise obsolete information so it got removed along with that information.
With localization for non-Latin languages on the support list the multibyte API doesn't cut it anymore. It neither can handle system text output outside the local code page nor can an ANSI window receive text input outside its own code page.
Similar problems exist for file names. With the multibyte API it is impossible to handle any file containing characters outside the active local code page.
So as of now, everything that may pass along some Unicode text will use the Unicode API with some text conversion functions. The only places where calls to the multibyte API were left are those where known string literals are passed or where the information is not used for anything but comparing it to other return values from the same API.
It now reads everything into a two-dimensional TMap and creates a list of mappings that apply to the current setting.
The constant need for reloading was the main blocker in redesigning how Dehacked strings get inserted. Currently they override everything, but IWAD-based Dehacked text shouldn't block PWAD overrides from PWADs' LANGUAGE lumps and instead be treated as coming from an [en default] block.
This also renames the main block from [enu default] to [en default], because it should be treated as the English default for all English locales and not just make it fall through to the base default as it did before.
Having everything lumped together made this a maintenance hassle because it affected how the level has to be stored.
This hasn't been tested yet, so it may not work as intended!
currentUILevel is now primaryLevel.
For ZScript, currentVMLevel was added. This is also exported as 'level' and will change as needed.
This also means that no breaking deprecations will be needed in the future, because in order to sandbox a level only 4 variables need to be handled: level, players, playeringame and consoleplayer.
The remaining global variables are not relevant for the level state.
The static 'level' has been mostly removed from the code except some places that still need work.
I think these were the last two still missing it, all remaining uses of the global level variable are in code that doesn't get run through a level tick and are supposed to access the primary level.
This is supposed to be come the place where all pure play code should be placed, but for that all CVARs and CCMDs and other things that do not directly handle play data should be taken out to make code reviewing easier. These now get collected in two separate files, g_cvars.cpp and g_dumpinfo.cpp respectively.
The sole ZScript property in here has also been moved - to thingdef_properties.cpp.
