fix vbos not being used for skeletal animations (50->770 fps jump, yes, really. OOPS!) so yeah, 7700% speedup there. lol... *sigh* fixed update notification prompt not appearing by splitting menu key dest into emenu+gmenu. thus the prompt is no longer killed by menu.dat starting up. fog command now displays a the extra params. rewrote console char handling to support 32bit unicode chars. font code does not support more than 16bit codepoints still, however. rewrote beam code in order to restore models on vid_restart. this solves a crash where they were invalid pointers afterwards. revived old menu_media, because jogi wanted shuffle. music now fades out for a sec when changing fake-cd-tracks. music no longer abruptly stops when changing maps. added fxaa support. reworked bloom a bit. can now bloom further. added r_renderscale cvar, for people that want supersampling (max 2), or subsampling for more speed or whatever. $timer now favours cvars with that name, rather than the $time macro. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4942 fc73d0e0-1445-4013-8a0c-d673dee63da5
