Spoike d078c85627 fix an issue with bloom by making sure a cvar is created for glsl to use (even if not directly used by the engine). this ensures there's no weirdness with defaults.
some fixes/tweaks for the nolegacy builds.
r_skybox works mid-map again.
tweak the qc debugger to not do infinite loops so easily...
rewrote chunks of the d3d11 renderer to support q3 shaders a little more correctly. now runs quake3 acceptably.
add explicit culldistance option for terrain/.map maps. pvs will effectively cut off anything beyond this distance.

All of Quake's data access is through a hierchal file system, but the contents of the file system can be transparently merged from several sources.
The "base directory" is the path to the directory holding the quake.exe and all game directories. The sys_* files pass this to host_init in quakeparms_t->basedir. This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory. The base directory is
only used during filesystem initialization.
The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to. This can be overridden with the "-game" command line parameter. The game directory can never be changed while quake is executing. This is a precacution against having a malicious server instruct clients to write files over areas they shouldn't.
The "cache directory" is only used during development to save network bandwidth, especially over ISDN / T1 lines. If there is a cache directory
specified, when a file is found by the normal search path, it will be mirrored
into the cache directory, then opened there.
