former used fistp, which is not portable across platforms, so cannot be
used in the play simulation. They were only suitable for the renderer.
xs_Float.h also has a very fast float->fixed conversion, so FLOAT2FIXED
uses that now.
(And I also learned that the FPU's round to nearest is not the rounding I
learned in grade school but actually Banker's Rounding. I had no idea.)
(Also, also, the only thing that could have made quickertoint faster than
toint was that it stored a 32-bit int. I never timed them, and I doubt in
practice there was any real difference between the two.)
- Changed atan2f to atan2. Using floats is not a win, because the result is
returned as a double on the x87 stack, which the caller then needs to cast
down to a float using fst/fld.

when a == 0x80000000, because the result of abs will still be negative as
long as we use signed math.
- Fixed: SafeDivScale31 performed DivScale32 instead.
- Fixed: R_DrawSpanP_ASM had a short jump into a different section.

- If you aren't targeting x86, m_fixed.h only includes basicinlines.h now.
- Moved x64inlines.h into basicinlines.h.
- Replaced uses of __int64 with types from doomtype.h.
- The stop console command no longer ends single player games, just the demo
that was being recorded.
- In C mode, the sc_man parser no longer allows multi-line string constants
without using the \ character to preface the newline character. This makes
it much easier to diagnose errors where you forget the closing quote of a
string.
- Fixed: V_BreakLines() added the terminating '\0' to the last line of the
input string.
- Added font as a parameter to V_BreakLines and removed its keepspace
parameter, which was never passed as anything other than the default.
