7499c84d0b - Add interpolatedhorizon() inlines to handle interpolating fixedhoriz objects without having to convert old and new values back to Q16.16 first. 2021-11-06 14:07:58 +11:00

86166f5e67 Revert "- xs_Float.h: Make all inlines return an unsigned value, and change previous unsigned inlines to signed." 
Revert "- `xs_Float.h`: Add `getint()` getter to `_xs_doubleints` struct."
Revert "- SW: When adjusting horizon in `DoPlayerDeathHoriz()`, just use integer horizon values and not Q16.16."
Revert "- Duke (RR): Clean up some unnecessary `FixedToFloat()` usage with the `fixedhoriz` `asbuildf()` method."
Revert "- `binaryangle.h`: Use `constexpr` on inline functions where it was previously not possible to do so."
Revert "- `m_fixed.h`: Use `constexpr` on inline functions where it was previously not possible to do so."
Revert "- `xs_Float.h`: Convert header to `constexpr`."

This does nor work as it violates the constexpr rules for unions. The code will error out on compilation for accessing an inactive member of a union.

082336e5f8 - buildhoriz: Implementation of pitch and BAM conversion code. 
* 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.
