- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.
- 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.
- This might have been added in an effort to fix problems caused by mixing inclusive
and exclusive right edges. It might not be needed anymore. Let's find out...
- did some cleanup on the portal interface on linedefs: All checks should go through isLinePortal (gameplay related) and isVisualPortal (renderer related) which then can decide on the actual data what to return.
- removed portal_passive because it won't survive the upcoming refactoring.
- removed all direct access to portal members of line_t.
- always use the precise (and fast) version of P_PointOnLineSide inside the renderer.
- 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.
- Renamed the 'noabsolute' parameter in side_t::GetLightLevel to 'is3dlight', what it actually is, to avoid the confusion that caused the abovementioned error.
- fixed: The Down2Up render path for sides of 3D floors had the 'is3dlight' check inverted.
This wants `curline->sidedef`, which is the 3D sidedef currently being
drawn. `sidedef` appears to be the last regular sidedef that happened
to be drawn? The perils of globals.
because they're kind of a pain to type when all uppercase.
- Also, make its sx1 and sx2 members shorts, so it takes less space, since
it's getting crammed into a vissprite now.
- This still doesn't use all the sprite properties correctly. It also
looks like they're going to need different code to build the clipping
arrays. But at least wall sprites are drawn at the proper angle now!
- R_AddLine() and R_RenderDecal() had nearly identical code for setting up
texture mapping. These have now been spun off into methods of
FWallCoords and FWallTmapVals.
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.
