* use static_assert directly. Raze is C++17, no need for that macro shit.
* removed CONSTEXPR - I seriously fail to see the use here, many of the functions marked as CONSTEXPR cannot possibly even be constant evaluated so the declaration makes no sense. Removed most of these and replaced the valid ones with the official constexpr keyword.
* got rid of EDUKE_PREDICT_FALSE - this makes zero sense in script parsing code, at best it will save a few microseconds. Clean code wins.
* replaced Blrintf with xs_CRoundToInt. Shitty name is shitty name, even if derived from POSIX.
* replaced Bstr*casecmp with str*icmp. As these get defined in the CMake project based on actual compiler checks they are preferable here.
* removed lots of other stuff that is not needed with a minimum compiler requirement of C++17.
* Remove fix16.h/cpp and utilise library from m_fixed.h.
* Extend m_fixed.h with two inline functions for int to/from float operations.
* Replace fix16_floor operations with those from xs_Float.h
* Replace multiple Q16.16 conversions from 0 to just be 0.
* Replaced all found in-game bit-shifts and multiplications/divisions with inline functions from m_fixed.h
* Replaced many casts of FRACUNIT as double in SW's panel.cpp as it is converted to double by way of type promotion.
* Fixed missed precision fixes in SW's panel.cpp where some types weren't declared correctly.
* Replaced 100+ `Cos()/Sin() >> 16` operations for Blood with inline functions `CosScale16()/SinScale16()`.
In particular this means to remove the option to disable widescreen aspect ratios. The way this was handled makes no sense with the current render backend.
The aspect ratio code will have to be redone entirely to properly obey the backend's settings.
* Breaks every other game except Duke unless/until they get migrated. Done for the purpose of demonstrating PR #244.
# Conflicts:
# source/build/src/timer.cpp
# source/games/duke/src/game.cpp
* rewrote all uses of timerSetCallback. Most were unnecessary or long obsolete, the sound updates need to run per frame, not per tic and the UI tickers need to be handled in the main loop anyway.
* Use a more precise timer to animate the menu transition.
* uncouple other menu animations from the game timer.
Avoid passing this anywhere in the client code. It should only be set right before rendering the 3D view and the only code using the base palette should be the 3D renderer and hud_drawsprite.
Also make the palette override CVARs 3D view only in debug mode.
* Returns a true double result.
* Also supports fractional input for fractional input. That is, if `sintable[1]` = 50 and `sintable[2]` = 100, `calcSinTableValue(1.5)` = 75.
* Increased precision of `BANG2RAD` define to use double and not float.
* As such, revert addition of `sintablef[]`.
- delete some voxel code that's software rendering only.
- apply Big Endian byte swapping for SFXs, as well, now that this no longer involves hacking the file system cache.
The entire method at use here is essentially not correct. Interpolation should be handled independently of the game timer directly based on the underlying clock, like in ZDoom.
There's interpolation bugs in the Build games that cannot be fixed if totalclock is used for it, but if we use something else we do not need a fractional totalclock.
* Changes performed in 0bd460d9e3 didn't take into account xdimenscale and viewingrangerecip like the days of old and this wasn't picked up in d80a32d379 or d80a32d379, where the applied fixes only appeared to work because they worked for me at 2560x1440p.
The math backend functions have been moved out of Build because they originally have a good license.

* Output from PrintVis() in 9dfd3ddd02 showed resulting global visibility as 0.078125.
* Following 0bd460d9e3, resulting global visibility shown as 0.041667.

This is to allow giving them a texture ID so that they can be used from ZScript which has no access to naked textures.
This also consolidates AnimTexture and VpxTexture.
There are effectively two states - the one in the backend and a local one in the drawer for the render list which is supposed to eliminate some of the more costly repeated calls.
This higher level state was cached globally, which did not work anymore because the real render state could be changed elsewhere without this code realizing it.
All this means that the render list drawer must create a new state cache for each call and also must apply its current pending render state before leaving to ensure that everything is properly reset.
The main reason here is that the scene specific part contains a projection dependent component which would be a problem when transitioning to GZDoom's code. The global viewpoint data already has a field for such a factor so now that gets used.
This also means a significant simplification of the visibility code in Polymost and the removal of several global variables.
Models are inoperable right now anyway so this would never get called, but it does a few things that would cause problems with refactoring the backend code.
