Adjusts the thing's 3D position on render side. This allows for adjusting a thing's visual position without impacting their hitbox.

- `DontLightOthers`: Acts as the inverse of `DontLightSelf`, where it won't light actors that aren't the owner.
- `DontLightMap`: The light doesn't affect the map.
The level’s global flag is unreliable and cannot be used. The operation this was initially supposed to skip cannot be skipped anyway so the impact should be minor.
* Added MF8_DONTFOLLOWPLAYERS.
Added the MF8_DONTFOLLOWPLAYERS flag, which allows friendly monsters to not follow their FriendPlayer when they have no target or goal left to head to.
* Changed the order that the DONTFOLLOWPLAYERS check runs in.
This is done to not produce unnecessary overhead on hostile monsters.
- GetTerrainDef takes the raw number of the Terrains[] index. Can return null.
- GetFloorTerrain (Sector) gets the defs from the position given (either Sector.Floor or Sector.Ceiling).
Turns out that there's a few old maps that have the extended line flags set but not the guard bit that forces their clearance.
Astrostein 1's first map is an example for this.
- Offset: The offset from the actor's view to move the camera about.
- Flags: (Default is -1, which means don't change flags)
- VPSF_ABSOLUTEOFFSET: Don't include actor angles in calculation.
- VPSF_ABSOLUTEPOS: Position is absolute, and disables all transformations. Modders are responsible for being portal aware!
Notes:
- `ViewPos` in Actor will be `null` until A_SetViewPos is called for the first time.
**Issues:**
- Hiding sprite while in portal incomplete.
- Previous comments in dobjgc.cpp suggested that StepMul was used
to determine how quickly garbage was collected based on how quickly
memory was being allocated. This was not the case. Now it is.
- Remove calls to CheckGC from the thinkers. With GC running at a
stable rate (once per frame), there should be no need to inject
pauses into the collection process to keep it from injecting stutters
(provided StepMul is sane). The risk of running out of memory because
we don't run a collection pass absolutely every thinker should be
practically zero.
- Reduce DEFAULT_GCMUL from 400 to 200, since it does what it says now
instead of something else.
