- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.
- some consolidation in p_map.cpp. PIT_CheckLine and PIT_FindFloorCeiling had quite a bit of redundancy which has been merged.
- čontinued work on FMultiBlockLinesIterator. It's still not completely finished.
Converting a floating point value that is out of range for a signed integer will result in 0x80000000 with SSE math, which is used exclusively for this purpose on modern Visual C++ compilers, so this cannot be used anywhere.
On ARM there's problems with float to unsigned int conversions.
xs_Float does not depend on these
- The original Doom renderer was inclusive for all right edges. This was
fine for the wonky projection it did. This was not fine for a standard
perspective divide, so I had to change walls to be right-edge exclusive
when I changed the projection. I only touched what was needed. Until
now. The right edge is always exclusive now, which should prevent any
more bugs related to mixing the two clusivities incorrectly.
- Since Clang++, G++, and VC++ all support this extension (even though it's
technically officially only part of C99), use it. It lets Clang's array-
bounds checker know that these are meant to be accessed out of their so-called
"bounds".
the camera is on. Mostly, this means testing the distance of the camera to the plane rather
than computing the plane's Z at the camera and comparing that with the camera's Z.

be used when for walls and floors when the renderer is paletted. The format
is very simple:
rgbtex1 paltex1
rgbtex2 paltex2
...
The first texture is the one to be used normally, and the second is the one
to be used in paletted modes.
The vid_nopalsubstitutions cvar can be used to ignore this lump.

GETPALOOKUP. The end result is that there is a minimum distance around you where light
amplification stops and it gets no brighter. Should this scale with visibility? I can't say.
So, yeah, it turns out all these years ago, I made this out to be harder than it really is.

- added Sector_SetTranslucent special so set translucency of portal planes at run time.
- added 'additive' information for portal planes. This is no-op at the moment because the flat drawers can't handle additive translucency yet though.

does not include xtoviewangle[centerx] in the mirroring so that the two columns at the center
of the screen do not map to the same angle. (BTW, this array is only used for the sky drawing.)

it happened outside the moved actor's Tick function. This got particularly
obvious with moving skybox viewpoints (See Daedalus's MAP21 intro for a good
example.)

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.
