Fixed up the -netquake / -spasm / -fitz args slightly, should actually be usable now. sv_mintic 0 is now treated as 0.013 when using nqplayerphysics, to try to make it smoother for nq clients. Preparing for astc's volume formats. Mostly for completeness, I was bored. Disabled for now because nothing supports them anyway. Fix broken mousewheel in SDL2 builds. Fix configs not getting loaded following initial downloads in the web port/etc. Make the near-cloud layer of q1 scrolling sky fully opaque by default (like vanilla). Sky fog now ignores depth, treating it as an infinite distance. Fix turbs not responding to fog. r_fullbright no longer needs vid_reload to take effect (and more efficient now). Tweaked the audio code to use an format enum instead of byte width, just with the same values still, primarily to clean up loaders that deal with S32 vs F32, or U8 vs S8. Added a cvar to control whether to use threads for the qcgc. Still disabled by default but no longer requires engine recompiles to enable! git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5683 fc73d0e0-1445-4013-8a0c-d673dee63da5

Threading:
|
|
When the main thread will harm the filesystem tree/hash, it will first lock fs_thread_mutex (FIXME: make a proper rwlock).
|
|
Worker threads must thus lock that mutex for any opens (to avoid it changing underneath it), but can unlock it as soon as the open call returns.
|
|
Files may be shared between threads, but not simultaneously.
|
|
The filesystem driver is responsible for closing the pak/pk3 once all files are closed, and must ensure that opens+reads+closes as well as archive closure are thread safe.
