This was done because the backdrop as implemented was the only texture in the entire game that had to be deleted and recreated each frame.
However, with Vulkan this would have necessitated quite a bit of synchronization with the render pipeline which wasn't really feasible just for this one single texture.
Now the texture manager can assume that once a texture was created it will be immutable and never has to change.
The old organization made sense when ZDoom still was a thing but now it'd be better if all pure data with no dependence on renderer implementation details was moved out.
A separation between GL2 and GL3+4 renderers looks to be inevitable and the more data is out of the renderer when that happens, the better.
This was originally invented to fix the sprite offsets for the hardware renderer.
Changed it so that it doesn't override the original offsets but acts as a second set.
A new CVAR has been added to allow controlling the behavior per renderer.
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.
- allow treatment as one-character string constants as character constants. This became necessary because name constants already use single quotes and are much harder to repurpose due to a higher degree of ambiguity.
- fixed: protected methods in structs were not usable.
This fixes an issue with DUMP 2 which looked for patches of the same name as the texture currently being defined and where the patches had the same use type as the composite texture. The function as implemented would only find the newly added composite and print an error.
If done earlier they will not be able to detect overrides of sprites and graphics which are not part of the PATCHES lump. There was some fudging code to work around this problem but it was only partially working.
Now these textures only collect the texture name and use type during setup and resolve them after all textures have been created.
- some reorganization of texture precaching so that the renderer can decide what to do with actors.
Just marking the sprite textures loses too much info if more is needed than just loading the images into memory.
The code assumed that it had access to the texture manager but that gets initialized after MAPINFO, which means that MAPINFO can only store the texture names and let the precaching code resolve the actual textures.
- Fixed: If a part of a multipatch texture is replaced by a HIRESTEX
version, the original patch must not be deleted, since the multipatch
texture still needs it for compositing.
- Fixed: PALVERS crashed with unknown textures since a value was never given for %s.
- Fixed: FON2 loader didn't set ActiveColors correctly.

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.
