attempt to provide some better gettext support for engine strings (especially cvar/command descriptions). still no translations available though. try to optimise hldml rendering a little. fix issue with menuqc models rendering as black when fog is active. use threads to try to reduce stalls from player-skin switches. add sys_clocktype cvar to linux builds too, with CLOCK_MONOTONIC by default. enable dtls certificate pinning log stuff. fix r_viewmodel_fov being used instead of fov cvar. fix possible segfault when egl driver fails. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5742 fc73d0e0-1445-4013-8a0c-d673dee63da5

/*

This is based on Jogi's OpenAL support.
|
|
Much of it is stripped, to try and get it clean/compliant.
|
|
|
|
Emscripten/WebAudio is buggy or limited.
|
|
This means we force distance models and use hacks to avoid bugs in browsers.
|
|
We also have no doppler with WebAudio.

underwater cacaphoy
|
|
openal bug with reverb. either disable reverb or disable openal.
|
|
|
|
"build/openal-soft-1.19.1/Alc/filters/filter.c:25: BiquadFilter_setParams: Assertion `gain > 0.00001f' failed." + SIGABRT
|
|
bug started with 1.19.1. Not fte's bug. either disable reverb or disable openal.
|
|
(happens when reverb properties are changed too fast)
|
|
|
|
AL_OUT_OF_MEMORY
|
|
shitty openal implementation with too-low limits on number of sources.
|
|
|
|
AL_INVALID_VALUE
|
|
shitty (apple) openal implementation with too-low limits on number of sources.
