Map things are writeable in Lua, which I am pretty certain is a mistake because mapthings are not sent over the network at all. I considered making them net-synced (it would be relatively easy), but it also aligns with another, more "philosophical" issue: Doom generally copies over properties from mapthing_t into mobj_t, and then only refers to it again when needing to respawn an object -- mapthing_t is not really intended to be referred to very often at runtime. At best it's slightly annoying since some objects rely on a spawnpoint for behavior changes, at worst it may make ACS more confusing in the future since Thing and Mobj tags are mixed together or less useful since they wouldn't be able to modify behaviors of objects that are based on args.
So I decided to solve these two issues at the same time; just treat mapthing_t as something to copy values from, like OG Doom does it. This basically just means that special and args are also part of the mobj now instead of the mapthing, which should fill any desire to edit this stuff from Lua, and reduces the number of instances where objects need to check for their spawnpoint to function properly.
Gremlins happened whenever P_TryMove and P_SlideMove/P_BounceMove disagreed on what an object collided with. When TryMove said you collided with a line, but P_BounceMove said that you didn't, then you'd get gremlin'd.
To fix this, P_TryMove now can edit a struct to contain information on what it collides with. P_SlideMove and P_BounceMove no longer try to detect walls on their own and now requires this result from P_TryMove. If a slide/bounce is needed without moving the object, then you'd want to use P_CheckMove to get the result.
Lua is not supported right now.
This makes it significantly easier to save/restore the state of these variables, whenever we need to do so for calling movement functions in the middle of other movement functions. This will also make it easier to move it out of global variable hell if desired later.
Squashed SRB2 2.2 Public uncapped without UDMF merge
Implement interpolation at the renderer level
Instead of interpolating thinkers, we interpolate mobjs inside the
renderer. Further interpolation is TBI.
Place Frame Interpolation in "Experimental" video options header
This seems like an appropriate way to describe the feature for now.
Add smooth level platter under interpolation, `renderdeltatics`
`renderdeltatics` can be used as a standard delta time in any place,
allowing for smooth menus. It will always be equal to `realtics`
when frame interpolation is turned off, producing consistent
framerate behavior everywhere it is used.
Add smooth rendering to save select screen
Add smooth rendering to Record/NiGHTS Attack, F_SkyScroll
Ensure viewsector is accurate to viewx/viewy
This fixes a potential crash in OpenGL when changing between levels.
Ensure + commands get executed before map start
Always have precise_t defined
Fix misc dropshadow issues
Reset view interpolation on level load
Remove unnecessary precipmobj thinker hack
Add reset interpolation state functions
Reset precip interpolation on snap to ceil
Reset mobj interp state on TeleportMove
Only swap view interp state if a tick is run
Run anti-lag chasecam at tic frequency
Fixes jittery and unstable chasecam in high latency netgames
Homogenize mobj interpolations

Interpolate HWR_DrawModel
Add functions to handle interpolation
Much less code duplication
P_InitAngle, to fix angle interpolation on spawning objects
Fully fix drop shadows
It used the thing's floorz / ceilingz directly -- that wouldn't account for interpolated coordinates.
Do not speed up underwater/heatwave effect in OpenGL
Closer OpenGL underwater/heatwave effect to Software
Interpolate from time of previous tic
Previously interpolated from last 35th of a second, which
may be offset from game time due to connection lag.
Consider this the proper fix to 6ecac4159a too.
Calculate FPS stuff even if frame is skipped
I decided ultimately to actually keep the frame skip optimization disabled, because I think it is actually a little bit helpful that you can still get accurate rendering perfstats while paused, however if we decide otherwise then we can have this optimization back without making the game act like it's lagging.
Keep rect in memory
Feel better about this than creating one all da time
Lots of FPS stuff
- Disabled VSync, due to the numerous problems it has.
- Instead, added an FPS cap.
- Frame interpolation is now tied to fpscap != 35.
- By default, the FPS cap is set to the monitor's refresh rate.
- Rewrote the FPS counter.
(This also consolidates several more commits ahead of this
fixing various issues. -eid)

Dynamic slope interpolators
I_GetFrameTime to try and improve frame pace

Fix flickering plane interpolation for OpenGL in the exact same way
Funny OpenGL renderer being at least 50% copy-pasted Software code :)
P_SetOrigin & P_MoveOrigin to replace P_TeleportMove
Convert P_TeleportMove use to origin funcs
Revert "P_InitAngle, to fix angle interpolation on spawning objects"
This reverts commit a80c98bd164a2748cbbfad9027b34601185d93f5.
Waypoint polyobjects interpolate z & children
Add interpolation to more moving plane types
Adds interpolation to the following:
- Crumbling platforms
- Mario blocks
- Floatbob platforms (this one works really strangely due to two thinkers, maybe double-check this one?)
Reset overlays interp states each TryRunTics
Interpolate model interpolation (lol)
Use interp tracer pos for GL linkdraw
Papersprite angle interpolation
Makes the ending signpost smooth
Move intermission emerald bounce to ticker
Bring back shadows on polyobjects
Also optimizes the method used so rings can show their shadows too. Using just the subsector is a tad bit imprecise admittedly but any more precise methods get really laggy.
Fix a bunch of ticking in hu_ drawing functions
Revert "Reset overlays interp states each TryRunTics"
This reverts commit a71a216faa20e8751b3bd0157354e8d748940c92.

(NiGHTS items for example).
Revert "Remove unnecessary precipmobj thinker hack"
This reverts commit 0e38208620d19ec2ab690740438ac2fc7862a49e.
Fix frame pacing when game lags behind
The frame timestamp should've been made at the start of the frame, not the end.
Fix I_FrameCapSleep not respecting cpusleep
Jonathan Joestar bruh
Allow dedicated to use precise sleep timing again
Instead of only using one old sleep, just enforce framerate cap to match TICRATE.
Make Lua TeleportMove call MoveOrigin
Reset Metal fume interp state on appear
Add interpdebug
Put interpdebug stuff in perfstats instead
Add timescale cvar
Slow the game down to debug animations / interpolation problems! Speed it up if you need to get somewhere quickly while mapping!
Enable timescale outside of DEVELOP builds
It has NETVAR, so it should be fine -- put an end to useful debugging features excluded in multiplayer!
Force interpolation when timescale != 1.0
Reset old_z in MT_LOCKON think
Fixes interpolation artifacting due to spawn pos.
Fix cutscenes in interp
Fix boss1 laser in interp
Interpolate mobj scale

THANKS SAL
Add Lua HUD drawlists
Buffers draw calls between tics to ensure hooks
run at the originally intended rate.
Rename drawerlib deltaTime to getDeltaTime
Make renderisnewtic is false between tics
I know what I'm doing! I swear
Completely refactor timing system
Time is now tracked internally in the game using I_GetPreciseTime
and I_UpdateTime. I_Time now pulls from this internal timer. The
system code no longer needs to keep track of time itself.
This significantly improves frame and tic timing in interp mode,
resulting in a much smoother image with essentially no judder at
any framerate.
Ensure mobj interpolators reset on level load
Ensure view is not interpolated on first frame
Disable sprite offset interpolation (for now)
Refactor timing code even more
System layer is greatly simplified and framecap
logic has been moved internally. I_Sleep now
takes a sleep duration and I_SleepDuration
generically implements a precise sleep with spin
loop.
Adjust spawned mobj z by gravity inversion
Only check VERTICALFLIP for old_z calc
Fix Marathon Mode menu for uncapped
Move screenshot code before timing
Only play emerald hunt sounds on new tics
Restore deleted zofs (fixes signpost sparkles etc)
Revert to before screenUpdate boolean was added
Was done this way for the sake of an older version of uncapped's timing; now that the new timing is much better, I decided it should remain as close to pre-uncapped as it can be.
Run UpdateLevelInterpolators in preticker
FixesKartKrew/Kart-Public#10
Run UpdateMobjInterpolators in preticker
Reset view interp in preticker
Add per-split player view resets
All my work thus far on solving the drawflag/renderflag/additive/subtractive conundrum.
Outstandng problems:
* Bad additive/subtractive tables means that they appear opaque except under certain conditions.
* No support for FOFs, Polyobjects, or linedefs in OpenGL yet.
* All OpenGL support mostly done blind, may or may not function in practice.
If nothing else, the hard engineering problems are solved and it's just bug hammering...
Polyobjects set translucency to 11 for additive, and 12 for subtractive
FOFs using the regular translucency settings set the top texture to #900 for additive, and #901 for subtractive
