* Remove joystick scaling from `CONTROL_GetInput()`.
* Store turnspeed as constant at top of `processMovement()` and use it for joystick yaw/pitch scaling. This adds the advantage of having the out-of-box turning speed match the keyboard's turn speed and also attenuates when the player is not running.
* When interpolating on the initial setup, when binangle reached an overflow point when going lower than zero, the engine was spinning the player around clockwise to the new angle (2047, for instance).
* Interpolating after casting as uint64_t with a workflow similar to the original games, the issue went away.
* Cleaned up other interpolation functions to be of a consistent workflow.
* Scale keyboard input turning down to degree speeds.
* Uplift some remaining Q16.16 code in `applylook()` to full BAM precision.
* Move static calculations of aim and look speeds for `sethorizon()` back into function since GameTicRate isn't set right before calculation is done.
* Simplify the angle target setup back to a basic value like before.
* Repair SW interpolation issues of weapon sprite drawer when rotating left/right.
* Fix SW death horizon constant values following change of horizon center to 0.
* Struct made up of binangle class units.
* Create signed clone of binangle for use with look_ang and rotscrnang.
* Append currently outgoing function names with `2` at the end to avoid conflict.
* Started with the most complicated game first.
* Struct made up of fixedhoriz class units.
* Append currently outgoing function names with `2` at the end to avoid conflict.
* Determined maximum horizon able to be handed by engine in Q16.16 format is 280039127.
* Re-did pitch math to work on this known maximum and standardised pitch around -90/90 degrees as it should be.
* Because pitch is now -90/90 and not ~-188/188, m_sensitivity_y probably requires re-scaling.
* Blood had this right. It makes sense that the horizon be based around as it's easier to work with.
* Removed all associated game math to deduct default horizon of 100 when doing weapon zvel etc, meaning actual horizon can just be used.
* Re-did return to center function to work on the already converted pitch. Return speed should be 1:1 with previous code.
This time there were 3 additional texts and the notify display, though, except for multiplayer content that wasn't touched yet.
The result is the same: No need to extend the tiny font with international characters
This essentially removes the tiny font which is simply too small to ever be able to receive a proper international extension from the equation for localization because the level name display was the only remaining relevant content using this font.
The only other screen where this font is still being used to draw text requiring translated content is the multiplayer summary which will have to be redesigned anyway if multiplayer becomes functional again.
* Reduce `hidInput->mouseturny` to previous scaling (0.25 of incoming input).
* Change `hidInput->mouseturnx` to be 0.5 of incoming input (33% slower than b57e13ff62, but matches what other ports by providing a 2:1 scale).
* Remove further divisions beyond m_side and m_forward and adjust code in `processMovement()` accordingly.
* Change scaling for `mousevelscale` in `processMovement()` to be 1/160th of keymove. Slightly lower for Duke and a lot faster for Blood where it's needed.
Apparently this is needed by some hires packs to fudge the sprite offsets.
Fortunately, setting sprite offsets is the only thing this was ever used for so it's relatively uninvasive.
