reduced input latency.
reworked how internal texture formats work,.
added support for LIGHTING_E5BGR9 bspx lump for HDR lighting.
updated support for srgb, no longer looks quite so weird. works on glx
vid_srgb 3 attempts to use half-float swapchains, where possible.
gl: use glTextureStorage where available.
d3d11: gave up on using dxgi for fullscreen, was just too buggy.
glx: updated gl context creation on linux.
server: fix svc_updatefrags not being passed though (fixes frikbot scores)
fs: spanned pk3s now work (fragmented files/directory will fail to open, so this needs a custom tool to be fully useful).
fixed restart_ents command (restarts the map, but preserving the players as they are)
tw: removed 'QWSKINS' featureset from tw config
