* 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()`.
This is because 'classic' aim mode will reset the view if the mouseaim key is not pressed.
The problem with this is that an empty input packet will trigger a view reset. If the meaning is inverted the default aim mode is free mouse view which doesn't try to alter any view state and is therefore preferable for an empty packet.
Fixes#292
This timer only gets incremented by the main game ticker when the playsim is running.
This timer gets used for all playsim-related timing and animations so that these are decoupled from imprecisions in the global timer.
* Tile set for `kSBarNumberAmmo` does not include a slash. Hack put in place to get me a slash from a specific tile of a different font. It "works" and I don't think it looks too bad.
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.
None of this was really working anymore, but will have to be rethought once a network stream exists again.
But even then, this is better sent as a separate command, and in MP only.
Currently the bit fields are still separate and they have to be merged, but for now the added memory does not matter.
Having this structure in the common parts will allow work on consolidating the input code, though.
Whatever this was for it made that thing extremely unwieldy.
With these merged the resulting structure doesn't look much different from Duke's anymore.
* Remove cast of int on `gFrameClock` since gFrameClock is now just an int.
* Remove unused `gFrameTicks`.
* Remove unused `gFrameRate`.
* Rename `gFrame` to `gFrameCount` so it's easier to search and distinguish from `gFrameClock` without relying on regex.
This needs to be called unconditionally for every frame being rendered, not all of the game modules did that.
Placing this call here ensures that it is independent of anything the games do.
* 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.
This removes most of the InputState class because it is no longer used.
The only remaining places still checking scan codes are the modifiers for sizeup and sizedown.
All the rest was remapped to safer methods. The multiplayer taunts are currently inoperable, they will need support of shift-bindings to get proper support.
