From the looks of it the engine calls the sound function repeatedly while the sound plays to perform distance checks.
With the OpenAL backend these checks are totally unnecessary and shouldn't do anything.
* Convert axes in ControlInfo struct from int32_t to float as what's received from the backend.
* Remove all the scale up/down math since we don't need that with floats and replace with float constants that match old behaviour.
* Store q16mlook scaling as a constant for use with mouse and upcoming controller code.
* Add required controller code to Blood as the only game not to have working controllers.
* Fix typos in (gInput.forward > input.forward) for `ctrlGetInput()` in Blood.
* Remove use of `scaleAdjustmentToInterval()` on Exhumed and Shadow Warrior as they only process forward/side velocities within the game's ticrate.
* Repair angvel/aimvel scaling mistakes from d79a5d256d.
* Scale dyaw and dpitch by 25% for Shadow Warrior as the game runs 25% faster than the other games, leading to faster input.
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.
* Repairs https://forum.zdoom.org/viewtopic.php?f=340&t=67239 and https://forum.zdoom.org/viewtopic.php?f=340&t=67933
* Values that come from GZDoom backend are too low to be suitable for the Build games which were dividing by 'analogExtent'.
* Remove definition of analogExtent from all games and define in inputstate.h, then define joyaxesScale as 75% of analogExtent to provide a bit of headroom and not have a scale of 1.0 be full speed.
* Invert the returned results of GetAxes() as the returned floats are reversed for build games.
* Leverage scaleAdjustmentToInverval() on game-side code to consistently scale the input irrespective of frame rate, vsync etc.
- Inline function returns a double, therefore we should use it and not potentially truncate the mantissa.
- Use divisors to get true numbers of some floats (3.333 -> 10/3, etc).
- Remove a few brackets/parentheses where possible from what are already exceedingly bracketed lines.
Since the same word gets used in text messages and local variables in the game code it is easier this way to search for it and facilitate its transition to the translation table management in PaletteContainer.
