* change the license of the main file because there is no more id-based code here licensed under the GPL.
* moved VM interface definition out of the implementation.
* moved idmus CCMD out of implementation because it is dependent on Doom level definitions.
* moved s_music.cpp into the music folder with the rest of the music code.
* moved the sprite renaming out of the file system entirely into a caller-provided callback.
* renamed several functions to closer match the terms of a file system.
* moved the VM interface out of the implementation.
These were creating dangerous interdependencies. It is better to do explicit conversions when needed.
As an added plus, this means that zstring.h no longer depends on name.h which was very annoying.
- replace swapvalues with std::swap globally.
- added some additions to utility code from Raze, mainly to reduce file content differences.
- reduced some unused utilities
This may look as a workaround, it is not.
nosave cvars are meant to be used as a storage for statistical data that doesn't
affect gameplay. That's why this data isn't saved to the savefile in the first
place. Therefore, there is no point in sending this data over network. It would
have no meaning on machines other than local.
The old method using a single string with a backslash as separator is unable to handle anything with actual backslashes in the data.
It now uses a JSON object with each CVAR being a separate key.
Also simplified the sound init decision making. With FMod gone there is no reason to be pedantic here. Even the check of snd_backend for the Null device could be omitted here, its only realistic use is '-nosound'.
- it disables most 2D drawing in order to favor a fullscreen output view for screenshot taking
- enabling the console or any menu should cancel it
- it does use several CVARs but their state should be restored when this mode is canceled
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.
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.
