* 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.
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.
This is to cut down on boilerplate code because these encode the virtual screen size in the mode parameter, making it unnecessary to specify a virtual size separately.
Taking a cue from GDX to properly synchronize it because PCExhumed's approach looked broken by design.
It had no frame rate sync and solely depended on the low level audio stream for it.
In other places I_GetEvent should be used to call the system's message pump and keep the app responsive, but all game side processing should be skipped.
