fteqw/plugins/cef/cef.c
Spoike 0c8ad17f7c Fix various compiler warnings. 
Added sv_guidkey cvar, allowing cross-server guid key generation (although it lacks auth).
Support .ico, because we can.
preliminary support for sdl 2.0.6's vulkan stuff. will wait till its actually released before its properly used.
Fix capturedemo.
videomap should typically use premultiplied alpha, apparently.
Updated sound drivers. No more old drivers. Better cvar registration. More drivers optionally support float output.
Added certificate log for dtls connections.
Rewrote font char cache, now supports full unicode char range, not just ucs-2. Attempt to support FreeType 2.5+ rgba fonts.
XMPP now supports carbons, and shows avatars in conversations. Updated xmpp's scram auth to be more strict, including the plus variation (hopefully), to block evil tls proxies.
ffmpeg plugin now uses the decoupled api for decoding too.
Cef plugin updated to support fte-scheme post data properly, as well as request/response headers (like cross-origin).
