This is mainly for future-proofing because storing these as objects in an array not only has a negative impact when using multithreading due to longer blocking time for the threads but also makes it hard to cache this data for reuse.
- with renderers freely switchable, some shortcuts in the 3D floor code had to be removed, because now the hardware renderer can get FF_THISINSIDE-flagged 3D floors.
- changed handling of attenuated lights in the legacy renderer to be adjusted when being rendered instead of when being spawned. For the software renderer the light needs to retain its original values.
* the MAPINFO options now get handled in g_mapinfo.cpp and g_level.cpp, just like the rest of them as members of level_info_t and FLevelLocals.
* RecalcVertexHeights has been made a member of vertex_t and been moved to p_sectors.cpp.
* the dumpgeometry CCMD has been moved to p_setup.cpp
This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
This has increasingly become an obstacle with the hardware renderer, so now the values are being stored as plain data in the sector, with the software renderer getting the actual color tables when needed. While this is a bit slower than storing the pregenerated colormap, in realistic situations the added time is mostly negligible in the microseconds range.
- disabled the Build map loader after finding out that it has been completely broken and nonfunctional for a long time. Since this has no real value it will probably removed entirely in an upcoming commit.
- for explicitly defined glows, use the one for the current animation frame, if an animated texture is active. For default glows it will still use the base texture's to avoid inconsistencies.
There's two restrictions, though:
* on one-sided-line portals fog boundaries will not be drawn.
* the filler sector behind the portal may not have a sky ceiling texture. This is because the drawing code contains several sky checks which get in the way here.
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.
This is slower than doing it in the render pass so it's only active when actually needed - it's also slower than using a client array so this code only gets used when there is no choice but to work with a 3.x core profile context.
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.
It makes no sense having them organized differently in this struct than what the rendering code needs. This saves one redundant copy operation and a function-local static variable.
