All CVars, mapinfo variables, and playerinfo/playerpawn variables are gone.
A Camera actor named 'SpectatorCamera' is defined in warsrc/static/zscript/actors/shared/camera.zs
The following new flag bits were defined in the 'DViewPosition' struct for use with actor->ViewPos in src/playsim/actor.h:
VPSF_ALLOWOUTOFBOUNDS = 1 << 3, // Allow viewpoint to go out of bounds (hardware renderer only).
VPSF_ORTHOGRAPHIC = 1 << 4, // Use orthographic projection.
VPSF_ISOMETRICSPRITES = 1 << 5, // Displace sprites towards camera and don't billboard (drawn from isometric perspective).
Basically, spawn a SpectatorCamera actor with the appropriate flags and set it to player.camera.

Has been tested with multiplayer death and disconnection (and respawns). Not tested with portals.
Still only works with hardware renderer (mostly). But should be compatible with older mods and libraries.
Revert "Restored r_orthographic behavior."

Revert "Changed all of the isometric functionality to mapinfo and playerinfo variables. Retained function of most of the CVars."
This reverts commit dc897eacc0.
Revert "Adding isometric camera mode with orthographic projection to current state of master branch of GZDoom."
This reverts commit d2c2c93cf1.
Especially in the thinker code this is needed for software rendering.
Strictly speaking, the software renderer should do the same, but it checks r_dynlight in so many places deep in the logic where the level is not available.
Prompted by 'Hurt' which has > 4000 lights and runs into both performance issues and unpredictable light selection for the limited amount of shadowmap slots.
It wasn't respecting the map's pixel ratio setting. This wouldn't have
been very noticeable with the default pixel ratio of 1.2 but it was
very obvious with 1.8.
* refactored FBoundingBox so that the game dependent members are global functions now.
* changed some methods of the model renderer to take a render style parameter instead of a full actor.
* made the portal state global, outside the framebuffer, because it is pure logic state without dependencies on the backend.
* took the setup functions out of FDynLightData - there is no need to have them as members and they age game dependent.
