*/
rewrote ban code, merging bans+nonbans+cuffs+mute+cripple+deaf+lagged+vip. added timeouts. new penalties have no dedicated command. use the addip command for it. maplist command now generates links. implemented skin objects for q3. added a csqc builtin for it. also supports compositing skins. playing demos inside zips/pk3s/paks should now work. bumped default rate cvar. added cl_transfer to attempt to connect to a new server without disconnecting first. rewrote fog command. alpha and mindist arguments are now supported. fog change also happens over a short time period. added new args to the showpic console command. can now create clickable items for touchscreen/absmouse users. fixed menus to properly support right-aligned text. this finally fixes variable-width fonts. rewrote console tab completion suggestions display. now clickable links. strings obtained from qc are now marked as const. this has required quite a few added consts all over the place. probably crappy attempt at adding joypad support to the sdl port. no idea if it works. changed key bind event code. buttons now track which event they should trigger when released, instead of being the same one the whole time. this allows +forward etc clickable buttons on screen. Also simplified modifier keys - they no longer trigger random events when pressing the modifier key itself. Right modifiers can now be bound separately from left modifiers. Right will use left's binding if not otherwise bound. Bind assumes left if there's no prefix. multiplayer->setup->network menu no longer crashes. added rgb colours to the translation view (but not to the colour-changing keys). added modelviewer command to view models. added menu_mods menu to switch mods in a more friendly way. will be shown by default if multiple manifests exist in the binarydir. clamped classic tracer density. scrag particles no longer look quite so buggy. added ifdefs to facilitate a potential winrt port. the engine should now have no extra dependencies, but still needs system code+audio drivers to be written. if it can't set a renderer, it'll now try to use *every* renderer until it finds one that works. added experimental mapcluster server mode (that console command). New maps will be started up as required. rewrote skeletal blending code a bit. added cylinder geomtypes. fix cfg_save writing to the wrong path bug. VFS_CLOSE now returns a boolean. false means there was some sort of fatal error (either crc when reading was bad, or the write got corrupted or something). Typically ignorable, depends how robust you want to be. win32 tls code now supports running as a server. added connect tls://address support, as well as equivalent sv_addport support. exposed basic model loading api to plugins. d3d11 backend now optionally supports tessellation hlsl. no suitable hlsl provided by default. !!tess to enable. attempted to add gamma ramp support for d3d11. added support for shader blobs to speed up load times. r_shaderblobs 1 to enable. almost vital for d3d11. added vid_srgb cvar. shadowless lights are no longer disabled if shadows are not supported. attempt to add support for touchscreens in win7/8. Wrote gimmicky lua support, using lua instead of ssqc. define VM_LUA to enable. updated saved game code. can again load saved games from vanilla-like engines. changed scale clamping. 0.0001 should no longer appear as 1. changed default mintic from 0.03 to 0.013 to match vanilla qw. I don't know why it was at 0.03. probably a typo. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4623 fc73d0e0-1445-4013-8a0c-d673dee63da5

openxr plugin: tweaked - inputs should be working properly now, and are visible to csqc. subject to further breaking changes, however. _pext_vrinputs: added cvar to enable vr inputs protocol extension allowing vr inputs to be networked to ssqc too. defaults to 0 for now, will be renamed when deemed final. updates menu: the prompt to enable sources is now more explicit instead of expecting the user to have a clue. updates menu: added a v3 sources format, which should be more maintainable. not final. updates menu: try to give reasons why sources might be failing (to help blame ISPs if they try fucking over TTH dns again). presets menu: no longer closes the instant a preset is chosen. some presets have a couple of modifiers listed. force the demo loop in the background to serve as a preview. prompts menus: now does word wrapping. ftemaster: support importing server lists from other master servers (requested by Eukara). server: try to detect when non-reply inbound packets are blocked by firewalls/nats/etc (using ftemaster to do so). qcvm: added pointcontentsmask builtin, allowing it to probe more than just world, with fte's full contentbit range instead of just q1 legacy. qcvm: memfill8 builtin now works on createbuffer() pointers. qcvm: add missing unsigned ops. Fixed double comparison ops. fixed bug with op_store_i64. added missing OP_LOADP_I64 qcc: added '#pragma framerate RATE' for overriding implicit nextthink durations. qcc: fixed '#pragma DONT_COMPILE_THIS_FILE' to not screw up comments. qcc: added __GITURL__ __GITHASH__ __GITDATE__ __GITDATETIME__ __GITDESC__ for any mods that might want to make use of that. qcc: fix up -Fhashonly a little setrenderer: support for vulkan gpu enumeration. rulesets: reworked to support custom rulesets (using hashes to catch haxxors, though still nothing prevents just changing the client to ignore rulesets) bspx: use our BIH code for the bspx BRUSHLIST lump instead of the older less efficient code. (static)iqm+obj: these model formats can now be used for the worldmodel (with a suitable .ent file). Also using BIH for much better collision performance. pmove: tried to optimise PM_NudgePosition, should boost fps in stress tests. wayland: fix a crash on startup. mousegrabs now works better. imagetool: uses sdl for previews. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5813 fc73d0e0-1445-4013-8a0c-d673dee63da5

this is hellish.
a hl model blends:
4 controllers (on a player, it seems each one of them twists a separate bone in the chest)
a mouth (not used on players)
its a sequence (to be smooth we need to blend between two frames in the sequence)
up to four source animations (ironically used to pitch up/down)
alternate sequence (walking+firing)
frame2 (quake expectations.)
this is madness, quite frankly.
luckily...
controllers and mouth control the entire thing. they should be interpolated outside, and have no affect on blending here
alternate sequences replace. we can just call this function twice (so long as bone ranges are incremental).
autoanimating sequence is handled inside HL_CalculateBones (sequences are weird and it has to be handled there anyway)
this means we only have sources and alternate frames left to cope with.
FIXME: we don't handle frame2.
