add `_surflight_color` key; allows overriding surface light color on an entity basis
load the .wal from wal_json and use the values as a base, if they exist
allow `_surflight_minlight_scale` to be specified on entities
Fixes bogus (huge integers) content stats reporting on macOS (also fix tjunc stats reporting)
having the non-copyable std::atomic<size_t> inside a std::any which must
be copyable was problematic
IMO this is slightly better because it lets us use non-copyable types
add a new meta format, which is just a JSON representation of the metadata contained in a .wal
simplify texture loading in `light`
fix `light` not handling replacement textures very well
string_iequals take string_view like the others
move averageColor to be alongside pixel data, where it belongs
move light-specific "load textures from BSP" routine to light
fix a couple bugs with external wad textures (there should always be at least a 40-byte miptex in there)
light can now load external textures
move -paths to common settings
fix bug with missing texture not filling miptex name
- for Quake-likes, WADs will be added as file system archives directly when the first brush is encountered since the wad key is ready to go by that point.
- after loading the .map and before constructing the BSP, what I call secondary textures (animation frames for Quake-likes) are added to the list, and the BSP's miptex data is filled.
- BSP miptex data is now opaque to the BSP process; the BSP simply copies the raw miptex information from the input. This simplifies the BSP structures and reading/writing routines.
- the img subsystem supports reading from raw miptexes now, although in practice this only happens for Quake-likes atm
- instead of a "wal cache", maps now have a "meta cache" which stores the metadata information for all games instead of just Quake II
- texture meta can now be ref'd out rather than needing to be copied every time (mainly only a gain for the std::string)
- wad.cc/wad.hh is gone; wads are now pushed into the filesystem archive
- fixed broken wad_archive
- fs subsystem iterated on a little bit; supports marking archives as external (only used for wads currently; see `LoadTextureData`)
- load_tga has better error handling
- add in foot-gun protection to the BSP readers; now they assert on failure to read instead of silently propagating that error throughout the rest of the process
- bsputil uses img stuff now, so it should handle palettes better
