player sprites will retain the same precision they had when they were
rendered as part of the 3D view. (needed for propery alignment of flashes
on top of weapon sprites) It worked just fine for D3D, but software
rendering was another matter. I consequently did battle with imprecisions
in the whole masked texture drawing routines that had previously been
partially masked by only drawing on whole pixel boundaries. Particularly,
the tops of posts are calculated by multiplying by spryscale, and the
texture mapping coordinates are calculated by multiplying by dc_iscale
(where dc_iscale = 1 / spryscale). Since these are both 16.16 fixed point
values, there is a significant variance. For best results, the drawing
routines should only use one of these values, but that would mean
introducing division into the inner loop. If the division removed the
necessity for the fudge code in R_DrawMaskedColumn(), would it be worth it?
Or would the divide be slower than the fudging? Or would I be better off
doing it like Build and using transparent pixel checks instead, not
bothering with skipping transparent areas? For now, I chop off the
fractional part of the top coordinate for software drawing, since it was
the easiest thing to do (even if it wasn't the most correct thing to do).

position when evicting sounds, because restarting the sound system causes
the DSP clock to restart at 0, so start times that were recorded before
the reset are no longer applicable after the reset.
- Fixed: S_StopChannel() always set the channel's actor to NULL, eliminating
origin information when resetting the sound system.

* when a logical condition was rewritten and inverted, one of the boolean test wasn't inverted along the rest. So the "monster must not be a player" was accidentally changed into "monster must be a player", which is usually going to be false... There's another minor, but related issue.

use a larger aiming range, and ignore non-targets in P_AimLineAttack().
- Added another parameter to P_AimLineAttack(): A target to be aimed at. If
this is non-NULL, then all actors between the shooter and the target will
be ignored.

SoundSequenceOnActor(int tid, string seqname);
SoundSequenceOnSector(int tag, string seqname, int location);
SoundSequenceOnPolyobj(int polynum, string seqname);
SoundSequenceOnSector takes an extra parameter that specifies where in the
sector the sound comes from (floor, ceiling, interior, or all of it). See
the SECSEQ defines in zdefs.acs.

may still be needed. In particular, when drawing a seg with a midtexture is
split by foreground geometry, the first drawseg generated from it will have
the correct WallSZ1,2 values, but subsequent ones will have whatever
R_RenderDecal() left behind. These values are used to calculate the upper
and lower bounds of the midtexture. (Ironically, my work to Build-ify things
had done away with these globals, but that's gone now.)

changing game code.
- made SpawningMapThing an argument of AActor::StaticSpawn instead of a global
variable.
- added a stub to the DECORATE parser for defining dynamic lights directly
in DECORATE. This is needed so that ZDoom remains compatible with any DECORATE
which uses this GZDoom feature in the future.

A_SetUserVar/SetUserVariable/GetUserVariable now take a variable name
instead of an array index. A_SetUserArray/SetUserArray/GetUserArray
have been added to access elements in user-defined arrays.

size textures at any scale. I also tried doing sky scrolling on the sky
cylinder, but that didn't look so good, so I left it in screen space.

but should use the camera position instead to get the correct position for
the closest point along the trail.
- Fixed: Explosions no longer caused splashes.
- Fixed: Copying translations to lower decals had the shade color check wrong.
- Fixed: Waggling floors did not move attached geometry.
- Cleaned up p_floor.cpp so that related parts of the code are grouped together.

a different default terrain than a generic solid surface.
- added format char processing to A_Print(Bold) and all printable messages
that can be defined in DECORATE.
- Fixed: The railgun code ignored MF3_ALWAYSPUFF.
- added desaturated translations.
- added optional state parameters to A_ReFire and A_GunFlash and A_CountdownArg.

can actually be used. In the end, all temporaries should be assigned to
unique virtual registers, and a register allocator can alias them to real
registers, but as long as we don't do any CSE, this is good enough for now.

- fixed: When a blasted actor collided with another one this other actor's
DONTBLAST flag was not checked.
- added a global DamageFactor actor property. All damage this actor takes is multiplied
by this factor in addition to damage type specific damage factors.

Currently, they're only good for disassembly and pasting into a proper text editor
for viewing.
- Fixed some problems with the FxExpression emitters that were revealed by actually
using them on the standard actors.

it isn't even used anywhere yet. In retrospect, I probably should have targeted an intermediate
representation and done codegen with that instead, since that would be something I can reuse.
