* 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()`.
