a4174352c7 - keep separate sector compare data for floor and ceiling.
Otherwise there can be problems if floor and ceiling change at the same time.

9cccd6f89b - store plane meshes without height information.
This avoids retriangulation when just the plane's z changes.

6239734bdc - always create geometry for flat sprites in the collection pass.
This still depends on Build's tsprite array which is global so its contents are too volatile for delayed geometry generation.
This needs to be refactored later but it can only be done when Polymost is gone.

4647a0b2bc - fixed cases of small textures being used for the sky.
Case in Point: DukeDC uses a 64x64 texture with palette remap for the sky.

6fcb6fa1d5 - sky positioning tweaks.
It does not use the panning info of the wall and needs a texture height relative adjustment.

2d0360fa55 - apply depth bias to translucent geometry.
This is necessary to handle wall and floor sprites placed on actual walls and floors work as intended.

e0fe8d2ed9 - fixed interpolation issues with sector objects in SW.
SO's vertex interpolation does not use the common framework so it got missed by the sector retriangulation checks.
We need to check two wall positions as well to make sure that sector movement is properly detected.

e8edb32e0d - fixed camera texture setup.
They still are upside-down but aside from that work as expected.

83760d4974 - fixed a few wall sprite rendering issues.
* masked walls were inserted into the sprite render list, causing sorting issues and depth fighting (see Duke's cameras and the 'closed' sign in Route66/Carnival.map)
* vertical and horizontal wall sprites needed their sorting functions swapped.
* plane clipping for wall sprites used bad coordinates.

fa44d75e98 - draw regular sprites.
Mostly functional, but the projected size is off.

efe0d57fca - removed all the decal stubs.
Build has wall sprite for decals so this is redundant and ultimately not usable.

098db655ab - did some fudging on the scene viewport until thinks looked right again.
I have no idea, though, why it has to be this particular formula, though. It doesn't seem to make any sense.

f6568fee0c - rewrote SW portal setup to use static data instead of ad-hoc setup.
This was by far the messiest game, there's two reasons for this.
First, the portal links do not need to be in an actual portal sector, so they cannot be used to detect portal sectors.
Second, the game moves portals in place, so all offsets are (0,0,0) so that not even these can be used for detection.

The only working method is the super-complicated original way to look up portals at run time, just being done at map start.
Having static portal links should reduce the render glitches quite significantly because the renderer knows now which sectors belong to a portal and can use this information to ensure proper processing.

af54cf3a3c - made SW's sector portals operational.
Unlike the other games these are so poorly defined that the engine has to rely on the original fudging to pick the proper portal to link to. As a result they are just as limited as they always were.
In addition all the portal search code had to be reinstated.

957f7e9487 - Accept binangle, fixedhoriz and lookangle classes in SetupViewpoint() vs. Q16.16 variables.
* Allows for more precision than Q16.16.
* Used as opportunity for `rollang` to be set using the `asdeg()` method, not `asbuildf()`.

e47b4507e4 - serialize the sector portal offset table.
Due to where this happens, the init code for these portals cannot be run when loading a savegame so it has to be saved.

1297e4ed02 - SW's line to sprite portals are working now.
Also fixed a clipper issue with Blood's line to line portals.

Christoph Oelckers
9903b39cf5 - make Blood's line to line portal operational.
Note that these portals cannot be rotated, so to preserve bad setups this limitation needs to be replicated.
If we want proper line to line portals for all games they need to be made a different portal type.

46e0b16370 - fixed ordering issues in drawer
* do not check the clipper in the collection pass to reduce number of bunches. Clipping here brings no performance gain.
* fixed the loop reset in FindClosestBunch to actually process the array's first element.
