Spoike 29cb22af8e try to fix vulkan validation warnings (and maybe some crashes on amd gpus) 
fix sdl1 not compiling.
fix temporalscenecache with q3bsp
add the net_wm_ping protocol to fte's native x11 stuff, allowing our process to be killed if we lock up (usually due to vulkan drivers...).
qccguiqt: actually save the config.
try to fix hl fonts
