disabled some quake-only teamplay stuff in non-quake builds. GL: r_dynamic -1 is now r_temporalscenecache 1, which makes menu options etc a little friendlier. fixed a serious memory leak. GL: Lightmaps are now uploaded using pbos to reduce cpu stalls (especially with temporalscenecache) and the resulting periodic framerate drops. Requires gl4.4. PM: moved manifest-downloads to the package manager. still needs some proper testing. PM: Fixed bug with downloading updates from every known mirror for that update. PM: Fixed bug with duplicate mirrors... PM: menuqc is now able to query available updates. engine's Draw_TextBox centers the text box more appropriately and easily. SV: added sv_autooffload cvar, when set the map command will automatically create a server in a separate process to reduce the effects of stutter in inefficient ssqc mods. Menu: menu_mods now shares data with getgamedirinfo builtin. MenuQC: Added some extra properties to the getgamedirinfo builtin. MenuQC: Added Menu_RendererRestarted entrypoint. MenuQC: _vid_renderer_opts cvar now has a value that actually reflects the windowing systems in the build, rather than just renderers. CQSC: Added getlocationname builtin. ALSA: device names are now more consistent with other audio drivers. SV: added unsavegame console command, to delete unwanted saved games. SV: hashtable entries are now saved into saved games. SV: reworked player remapping strategy when loading games. Player slots are now directly swapped serverside, not reconnected. SV: resend all csqc entity state when a client signals that it started recording a demo. SV: Added SOLID_BSPTRIGGER as a shapely alternative to the aabb SOLID_TRIGGER. modelindex must still be set for this to work. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5668 fc73d0e0-1445-4013-8a0c-d673dee63da5

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
