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.
- moved parts of the render setup out of the separate render functions.
Things like particle and polyobject linking were duplicated several times for rendering different things in different renderers.
These things only need to be set up once before the renderer is started so it makes a lot more sense to consolidate them into one place outside the actual rendering code.
There is no need to do this deep inside the renderer where it required code duplication and made it problematic to execute on multiple levels.
This is now being done before and after the top level call into the renderer in d_main.cpp.
This also serializes the interpolator itself to avoid problems with the Serialize functions adding the interpolations into the list which can only work with a single global instance.
Since currently there is only one level, this will obvciously only run once on that level for the time being.
This is mainly used for CCMDs and CVARs which either print some diagnostics or change some user-settable configuration.
Doing this intermingled with the thinkers is highly unsafe because there are absolutely no guarantees about order of execution.
Effectively it ran these commands right in the middle of the playsim which could cause all sorts of synchronization issues, because CCMDs are part of the UI, not the playsim.
- pass a const string to AddCommandString.
This function manipulated the input buffer, leading to all sorts of code contortions to make sure that the passed parameter is clean for that.
This function will now create a copy of the passed parameter which it can manipulate without complicating its calling code.

This also changes the action special interface to pass a Level parameter to the separate functions and makes a few other minor adjustments to the polyobject code.
This should be less of a drag on the playsim than having each light a separate actor. A quick check with ZDCMP2 showed that the light processing time was reduced to 1/3rd from 0.5 ms to 0.17 ms per tic.
It's also one native actor class less.
The mod which prompted me to add this is "The Chosen" which is a Dehacked-based TC and repurposes many original actors for something entirely different.
The stock lights are not usable for this and would make it impossible to add a GAMEINFO lump to it because then there is no way to disable loading of lights in the startup screen.
This was done to make reviewing easier, again because it is virtually impossible to search for the operators in the code.
Going through this revealed quite a few places where texture animations were on but shouldn't and even more places that did not check PASLVERS, although they were preparing some paletted rendering.
- moved the ALTHUDCF parser PClass::StaticInit, so that it gets done right after creating the actor definitions.
All left to do is not to reallocate the AltHud object for each frame but store it in a better suited place.
For this to work the 2D mode has to be properly set and unset at the right places so that no double mapping occurs and no render operation can happen while in 2D mode.
