make a guess at the currently applied preset. fix issues with vid_reload on preset changes being buggy. fix erroneous weapon flashes due to limited precision. try to fix rogue finale. fix issue with vid_restart crashing with directinput active. work around emscripten rand entropy, at least as far as particles are concerned. properly implement te_explosion2 (for rogue mission pack). drastically reduce submodel polyoffsets in the webgl port, because firefox's depth precision is 16 bit or something stupid. fix rogue ibar background not being used with qw hud. added terrain editor feature to edit the bsp's entity lump. this also works with .bsps. added console command to reload the map/apply those ent changes but leaving the players how they were (lets hope enemy etc stuff doesn't bug out...) force-enabled airstep when travelling fast. this is to partly replicate nq player physics in order to fix windtunnels on r1m5 iirc. added some more effects to the 'high' particle effect, in order to make rogue feel a little more loved. fix for rogue buzzsaws. rework webgl pointer locks. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4965 fc73d0e0-1445-4013-8a0c-d673dee63da5
