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

Too many changes, sorry. Change revision displays, use the SVN commit date instead of using __DATE__ (when there's no local changes). This should allow reproducible builds. Added s_al_disable cvar, to block openal and all the various problems people have had with it, without having to name an explicit fallback (which would vary by system). Add mastervolume cvar (for ss). Add r_shadows 2 (aka fake shadows - for ss). Add scr_loadingscreen_aspect -1 setting, to disable levelshots entirely, also disables the progress bar (for ss). Better support for some effectinfo hacks (for ss). Added dpcompat_nocsqcwarnings (because of lazy+buggy mods like ss). Rework the dpcsqc versions of project+unproject builtins for better compat (for ss). Added dpcompat_csqcinputeventtypes to block unexpected csqc input events (for ss). Better compat with DP's loadfont console command (for ss). Added dpcompat_smallerfonts cvar to replicate a DP bug (for ss). Detect dp's m_draw extension, to work around it (for ss). Cvar dpcompat_ignoremodificationtimes added. A value of 0 favour the most recently modified file, 1 will use DP-like alphabetically sorted preferences (for ss). loadfont builtin can now accept outline=1 in the sizes arg for slightly more readable fonts. Fix bbox calcs for rotated entities, fix needed for r_ignorenetpvs 0. Hackily parse emoji.json to provide :poop: etc suggestions. Skip prediction entirely when there's no local entity info. This fixes stair-smoothing in xonotic. screenshot_cubemap will now capture half-float images when saving to ktx or dds files. Fix support for xcf files larger than 4gb, mostly to avoid compiler warnings. Fixed size of gfx/loading.lmp when replacement textures are used. Added mipmap support for rg8 and l8a8 textures. r_hdr_framebuffer cvar updated to support format names instead of random negative numbers. Description updated to name some interesting ones. Perform autoupdate _checks_ ONLY with explicit user confirmation (actual updating already needed user confirmation, but this extra step should reduce the chances of us getting wrongly accused of exfiltrating user data if we're run in a sandbox - we ONLY ever included the updating engine's version in the checks, though there's nothing we can do to avoid sending the user's router's IP). Removed the 'summon satan all over your harddrive' quit message, in case paranoid security researchers are idiots and don't bother doing actual research. Removed the triptohell.info and fte.triptohell.info certificates, they really need to stop being self-signed. The updates domain is still self-signed for autoupdates. Video drivers are now able to report supported video resolutions, visible to menuqc. Currently only works with SDL2 builds. Added setmousepos builtin. Should work with glx+win32 build. VF_SKYROOM_CAMERA can now accept an extra two args, setviewprop(VF_SKYROOM_CAMERA, org, axis, degrees). Removed v_skyroom_origin+v_skyroom_orientation cvars in favour just v_skyroom, which should make it behave more like the 'fog' command (used when csqc isn't overriding). Added R_EndPolygonRibbon builtin to make it faster+easier to generate textured ribbon/cable/etc wide lines (for TW). sdl: Fix up sys_sdl.c's file enumeration to support wildcards in directories. edit command now displays end1.bin/end2.bin correctly, because we can. Finally add support for f_modified - though ruleset_allow_larger_models and ruleset_allow_overlong_sounds generally make it redundant. Fix threading race condition in sha1 lookups. Updated f_ruleset to include the same extra flags reported by ezquake. A mod's default.fmf file can now contain an eg 'mainconfig config.cfg' line (to explicitly set the main config saved with cfg_save_auto 1 etc). fmf: basegame steam:GameName/GameDir can be used to try to load a mod directory from an installed steam game. The resulting gamedir will be read-only. HOMEDIR CHANGE: use homedirs only if the basedir cannot be written or a homedir already exists, which should further reduce the probability of microsoft randomly uploading our data to their cloud (but mostly because its annoying to never know where your data is written). Fixed buf_cvarlist, should work in xonotic now, and without segfaults. Added an extra arg to URI_Get_Callback calls - the response size, also changed the tempstring to contain all bytes of the response, you need to be careful about nulls though. Try to work around nvidia's forced-panning bug on x11 when changing video modes. This might screw with other programs. sdl: support custom icons. sdl: support choosing a specific display. Added some documentation to menuqc builtins. menusys: use outlines for slightly more readable fonts. menusys: switch vid_width and vid_height combos into a single video mode combo to set both according to reported video modes. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5581 fc73d0e0-1445-4013-8a0c-d673dee63da5

fix colormod added frag message filter, and dedicated frag tracker. added 'windowed consoles' for social-type stuff without depending upon csqc mods for it. added in_deviceids command which allows listing/renumbering device ids. slider widgets now support inverted ranges, so gamma selection isn't so weird. fix top/bottom colour selection bug. software banding feature is now part of the 'software' preset (now that it supports mipmaps). support for loading .maps, and editing their brushes etc (with appropriate qc mod). 'map mymap.map' to use. expect problems with missing wads and replacement textures overriding them and messing up texture scales. snd_inactive is now default. fix threading issue with wavs, no more error from 0-sample-but-otherwise-valid wavs. added -makeinstaller option to embed a manifest inside the exe (and icon). the resulting program will insist on installing the game if its run from outside a valid basedir. framegroup support for q1mdl. textures are now loaded on multiple worker threads, for reduced load times. moo har har. netgraph shows packet+byte rates too. added r_lightstylescale, pretty similar to contrast, but doesn't impose any framerate cost, but may have overbrighting issues. r_softwarebanding now works on q2bsp too. fixed crepuscular lights. gzip transfer encoding is performed while downloading, instead of inducing stalls. FINALLY fix ezquake download compat issue (dimman found the issue). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4851 fc73d0e0-1445-4013-8a0c-d673dee63da5

fix colormod added frag message filter, and dedicated frag tracker. added 'windowed consoles' for social-type stuff without depending upon csqc mods for it. added in_deviceids command which allows listing/renumbering device ids. slider widgets now support inverted ranges, so gamma selection isn't so weird. fix top/bottom colour selection bug. software banding feature is now part of the 'software' preset (now that it supports mipmaps). support for loading .maps, and editing their brushes etc (with appropriate qc mod). 'map mymap.map' to use. expect problems with missing wads and replacement textures overriding them and messing up texture scales. snd_inactive is now default. fix threading issue with wavs, no more error from 0-sample-but-otherwise-valid wavs. added -makeinstaller option to embed a manifest inside the exe (and icon). the resulting program will insist on installing the game if its run from outside a valid basedir. framegroup support for q1mdl. textures are now loaded on multiple worker threads, for reduced load times. moo har har. netgraph shows packet+byte rates too. added r_lightstylescale, pretty similar to contrast, but doesn't impose any framerate cost, but may have overbrighting issues. r_softwarebanding now works on q2bsp too. fixed crepuscular lights. gzip transfer encoding is performed while downloading, instead of inducing stalls. FINALLY fix ezquake download compat issue (dimman found the issue). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4851 fc73d0e0-1445-4013-8a0c-d673dee63da5
