* 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.
* Need SW's input helpers available for Blood but therefore also need an angle delta function that does not seem to exist in Blood.
* Realise that gamecontrol.h/cpp might not be the most appropriate place, but it's a shared location and these will go into binaryangle.h when its utilisation can be more realised.
* Because SW's logic was reversed, in that param #1 was the new angle and param #2 was the current, all calls have been reversed.
* By happenstance, also fixes an issue with multiple 180° turns in quick succession.
* 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()`.
* Duke used `ototalclock` only to keep track of when the game ticked. SW uses it in the rendering code for differentials between tics so we should preserve that to prevent issues down the track.
less dependent on the frame rate.
It would probably be better to update this from the game loop side,
like in Duke3D, but it's still better than the preceding situation.

- videoNextPage() moved to after restoring interpolations.
- Properly use Q16.16 in as many places as possible. This fixes the angle/X-axis issues.
- Remove unnecessary call to timerUpdate() in main loop, only needs calling once and is called by eventhandlers().
This removes the last active use case for the software renderer and allows rendering the camera views at a higher resolution.
For Shadow Warrior this necessitated a split of JS_DrawMirrors, because it processed cameras and mirrors in the same loop which cannot be done with the hardware renderer.
All games combined there's 11(!!!) scene render blocks, not counting the sub-blocks for ROR and mirrors.
Does it surprise anyone that most of these sub-blocks do not feature all engine capabilities?
* removed all cases of getting a sound handle and checking it later.
* In particular, refactor the cases where the handle is stored in a static local variable. These are fundamentally unsafe because nothing maintains these local variables.
* finished rewriting the PlaySound function. Let's hope this is what was intended, the entire coding here was not particularly good, mixing high and low level sound handling all on the same level.
* call the update routine each tic and not merely every 4th or 8th one, this kind of granularity was ok in 1997 but not with a modern sound engine.
