git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5431 fc73d0e0-1445-4013-8a0c-d673dee63da5
Added .psd, .pbm/.pgm/.ppm, .pfm, and .hdr image formats. Extensions NOT added to r_imageextensions.
png (and the above formats) can now be loaded as RGBA16, instead of being truncated to RGBA8 (8bit pngs not affected).
r_imagelist will now show images from memory, instead of potentially loading new/different ones from disk.
Fix serverbrowser bug being too eager to join the server (eg from alt+tab).
Don't send ipv6 packets to qw/q2 masters. They won't be able to report ipv6 addresses anyway, and this reduces warnings when a host STILL has no ipv6 (my ISP sucks). this does not affect q3/dpmasters, for people without ipv4 addresses.
Tried to improve compat with Bloodshot's particle effects.
Fixed a couple of issues with R_AddTrisoup.
Fixed string tokenizing bug where it was using the wrong buffer size values.
Don't show link-local/localhost addresses in eg the status command (unless developer).
qtv-rel is now an easier target, for new qtv releases.
qtv warning fixes.
added a nailtrail effect to 'high' particles.
fixed terrain shaders.
fixed fogged water issue (on one of bal's maps).
first attempt at gltf2 format support
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5400 fc73d0e0-1445-4013-8a0c-d673dee63da5
Console code no longer makes assumptions about con_main
Screenshots rework, for screenshot_360, but also some other cleanups.
Fixed an issue with beginpolygon (finally).
Added per-rtlight style strings.
Added cvar to control whether ents will be culled by fog.
Added define to disable IPLOG, etc.
Added r_editlights cvar and related commands, for whenever csaddon isn't available.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5338 fc73d0e0-1445-4013-8a0c-d673dee63da5
Fix potentially serious crash with sprites+csqc tracelines.
Reworked fallback mouse cursor.
Fix decals on q3 bmodels.
Double-click to select a work to copy is now implemented.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5323 fc73d0e0-1445-4013-8a0c-d673dee63da5
Enclosed mvd recording in ifdefs, so it can be disabled at compile-time for any mods that don't want to have to deal with it.
Removed the recorded players thing.
Allow csqc to use EF_FULLBRIGHT.
Fix cl_pure to attempt to actually download missing packages.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5303 fc73d0e0-1445-4013-8a0c-d673dee63da5
Stripped obsolete vk_nv_dedicated_allocation extension.
Misc fixes for warnings.
Linux now defaults to using ~/.local/share/fte instead of ~/.fte for greater consistency.
Other misc linux tweaks.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5267 fc73d0e0-1445-4013-8a0c-d673dee63da5
Attempted to clean up build configs slightly, now ALWAYS using a build config.
Now enabling wayland renderer by default on linux (activates by default only when x11 fails).
Given linux servers the ability to chroot (will be used by default if run as suid-root).
Fixed a couple of vulkan warnings.
Makefile now treats speex like any other library.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5227 fc73d0e0-1445-4013-8a0c-d673dee63da5
remove MAX_MAP_LEAFS limit, although its still checked for sanity (just MUCH higher). You may need 64bit processes on account of the pvs+phs memory required.
integrated my fork of frikdec into fteqccgui. Just associate .dat with fteqccgui and it'll decompile the progs (compiling will then embed the decompiled source into the resulting .dat to avoid repeated decompilation). Be sure to back up first... not tested as a 64bit process.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5114 fc73d0e0-1445-4013-8a0c-d673dee63da5
splitscreen: split spectator setting into a per-seat setting. scoreboards are now also per-seat.
added parm_string global for richer map change stuff.
dpp7: fixed and reinstated.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5110 fc73d0e0-1445-4013-8a0c-d673dee63da5
schannel (ie: windows native) works as a client, not a server.
gnutls provides both client+server support. servers need to load a pre-generated cert from disk.
tweaked gamepads to actually work in the web target.
tweak gamepads a bit. added gp_* bind aliases. xinput+sdl+web should all use the same key mappings.
finally added the itemtimer glsl.
tweaked software renderer to not be quite so buggy, but you probably won't realise that if you try it.
disabled the ill-fated QWOVERQ3 feature.
don't do the oldorigin thing in quakeworld mods. hopefully this'll fix cspree's weird stuck-in-floor issue.
dpp7 is buggy serverside. disabled for now. I'm part way through rewriting its deltas.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5103 fc73d0e0-1445-4013-8a0c-d673dee63da5
reworked network addresses to separate address family and connection type. this should make banning people more reliable, as well as simplifying a whole load of logic (no need to check for ipv4 AND ipv6).
tcpconnect will keep trying to connect even if the connection wasn't instant, instead of giving up instantly.
rewrote tcp connections quite a bit. sv_port_tcp now handles qtv+qizmo+http+ws+rtcbroker+tls equivalents.
qtv_streamport is now a legacy cvar and now acts equivalently to sv_port_tcp (but still separate).
rewrote screenshot and video capture code to use strides. this solves image-is-upside down issues with vulkan.
ignore alt key in browser port. oh no! no more red text! oh no! no more alt-being-wrongly-down-and-being-unable-to-type-anything-without-forcing-alt-released!
reworked audio decoder interface. now has clearly defined success/unavailable/end-of-file results. this should solve a whole load of issues with audio streaming.
fixed various openal audio streaming issues too. openal also got some workarounds for emscripten's poor emulation.
fixed ogg decoder to retain sync properly if seeked.
updated menu_media a bit. now reads vorbis comments/id3v1 tags to get proper track names. also saves the playlist so you don't have to manually repopulate the list so it might actually be usable now (after how many years?)
r_stains now defaults to 0, and is no longer enabled by presets. use decals if you want that sort of thing.
added fs_noreexec cvar, so configs will not be reexeced on gamedir change. this also means defaults won't be reapplied, etc.
added 'nvvk' renderer on windows, using nvidia's vulkan-inside-opengl gl extension. mostly just to see how much slower it is.
fixed up the ftp server quite a lot. more complete, more compliant, and should do ipv6 properly to-boot. file transfers also threaded.
fixed potential crash inside runclientphys.
experimental sv_antilag=3 setting. totally untested. the aim is to avoid missing due to lagged knockbacks. may be expensive for the server.
browser port's websockets support fixed. experimental support for webrtc ('works for me', requires a broker server).
updated avplug(renamed to ffmpeg so people know what it is) to use ffmpeg 3.2.4 properly, with its new encoder api. should be much more robust... also added experimental audio decoder for game music etc (currently doesn't resample, so playback rates are screwed, disabled by cvar).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5097 fc73d0e0-1445-4013-8a0c-d673dee63da5
addtrisoup_simple now supports line lists too.
fix a memory leak in the sound code.
fix chunked http download corruption in certain cases.
reworked the networking associated with entity editing. now carries ids instead of indexes (qc isn't aware of them).
'map blarg.map' will now auto-create a dummy map if it does not already exist. this should make it easier to get started with map editing.
fix some issues with banning yourself - loopback can now mute etc themselves, but not ban themselves.
downloads/updates menu now handles plugin detection. user-installed plugins will result in a prompt allowing the user to enable/disable/delete them. This makes using plugins more explicit.
revamped help menu to remove m_state
fix silly ode copypasta bug, added preliminary bullet code in case anyone is interested.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5090 fc73d0e0-1445-4013-8a0c-d673dee63da5
package manager: reworked to enable/disable plugins when downloaded, which can also be present-but-disabled.
package manager: display a confirmation prompt before applying changes. do not allow other changes to be made while applying. prompt may be skipped with 'pkg apply' in dedicated servers.
sv: downloads are no longer forced to lower case.
sv: added sv_demoAutoCompress cvar. set to 1 to directly record to *.mvd.gz
cl: properly support directly playing .mvd.gz files
menus: reworked to separate mouse and keyboard focus. mouse focus becomes keyboard focus only on mouse clicks. tooltips follow mouse cursors.
menus: cleaned up menu heirachy a little. now simpler.
server browser: changed 'hide *' filters to 'show *' instead. I felt it was more logical.
deluxmapping: changed to disabled, load, generate, like r_loadlit is.
render targets api now supports negative formats to mean nearest filtering, where filtering is part of texture state.
drawrotpic fixed, now batches and interacts with drawpic correctly.
drawline fixed, no interacts with draw* correctly, but still does not batch.
fixed saving games.
provide proper userinfo to nq clients, where supported.
qcc: catch string table overflows safely, giving errors instead of crashes. switch to 32bit statements if some over-sized function requires it.
qtv: some bigcoords support tweaks
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5073 fc73d0e0-1445-4013-8a0c-d673dee63da5
make the 'identify' command assume that a single decimal number is not an address (allowing it to be handled as a user id).
qcc: support default initialisers in function calls.
tweak filesystem code to try to flush individual files instead of discarding the entire fs hash.
fix 'snap' stuff.
other tweaks...
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5058 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix fteqcc issue unintentionally stripping things
added model event support.
added support for a couple of extra twiddles in the iqm format.
modelviewer now highlights meshes (to display hitmesh areas).
modelviewer now shows ragdolls, because I can.
fixed some nq download issues/crashes/fallbacks.
fixed 8bit bmp palette issue.
added capturethrottlesize cvar to throttle recording speed if disk space is getting low (to avoid Maverick's demo encoder getting swamped).
com_protocolname can now list multiple protocol names to list multiple server types. only the first will be reported to other clients however.
can now be compiled without support for q1bsp or q1mdl. not useful, but hey.
increase max_channels, by as much as is necessary.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5038 fc73d0e0-1445-4013-8a0c-d673dee63da5
server: my attempt at mvd recording fixes. there's a couple of other issues, at least with nq mods.
client: properly support recording .dems mid-map for 15+666
client: server browser now queries nq servers for players+rules.
renderer: add support for single-image dual-layer skies that some other engines use.
qcc: add #merge, along with __wrap + __weak keywords. fix a symboldata issue revealed by this.
qcc: added a flag to write the sourcecode into the .dat (zip format compatible with any zip program that can deal with 'self extractors').
qccgui: can be told to open a .dat file instead of .src, showing/using any embedded sourcecode.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5017 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to appease msvc6, just because.
update the downloads menu. now even betterer!...
fix proquake server angle snapping precision issue.
also accept _glow textures as an alternative to the more standard _luma.
compat for dp_water shader terms. tcgen stuff is still fscked up.
menu tooltip code can now properly deal with variable width etc stuff.
add missing te_flamejet builtin.
r_dynamic -1 can now cope with q3bsp for a small speedup.
added -watch commandline arg, to make it easier to figure out where cvar changes are coming from.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5015 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some more compile-time issues.
fix some vulkan issues that are probably what's breaking amd gpus.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5005 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix q2bsp textures.
fix some vulkan validation issues.
MOVE_OTHERONLY is now an official feature (replacing MOVE_ONLYENT which is now removed, same functionality, better behaved behaviour).
network up edited brushes on initial connect. still needs more work for entity editing, but should otherwise be okay for now.
add sys_browserredirect console command for emscripten builds (can be used to trigger window redirections - including download requests)
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5001 fc73d0e0-1445-4013-8a0c-d673dee63da5
vulkan, wasapi, quake injector features added.
irc, avplug, cef plugins/drivers reworked/updated/added
openal reverb, doppler effects added.
'dir' console command now attempts to view clicked files.
lots of warning fixes, should now only be deprecation warnings for most targets (depending on compiler version anyway...).
SendEntity finally reworked to use flags properly.
effectinfo improved, other smc-targetted fixes.
mapcluster stuff now has support for linux.
.basebone+.baseframe now exist in ssqc.
qcc: -Fqccx supports qccx syntax, including qccx hacks. don't expect these to work in fteqw nor dp though.
qcc: rewrote function call handling to use refs rather than defs. this makes struct passing more efficient and makes the __out keyword usable with fields etc.
qccgui: can cope a little better with non-unicode files. can now represent most quake chars.
qcc: suppressed warnings from *extensions.qc
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5000 fc73d0e0-1445-4013-8a0c-d673dee63da5
fixed most gcc warnings when compiling for linux.
client can now connect to 10002 servers. probably 10000+10001 too, but too lazy to test.
doom3 map loading is working again, but has too many issues for it to be useful (leaks, premature purges, no texture_d suffix support), so its still disabled for now.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4999 fc73d0e0-1445-4013-8a0c-d673dee63da5
device ids with rawinput and xinput are now assigned only on the first event. this means the ordering is easily controllable, thus helping splitscreen usability.
fix compile errors with the nolegacy builds.
client updates "chat" userinfo to match ezquake. does not display them still. server now forwards them correctly for ezquake.
android can now switch gles version. a bit crashy with it though.
android: gyroscope is now available to csqc.
android: added vid_dpi_x/y cvars. will be 0 on other platforms, for now.
added screenshot_vr command, for 360-degree stereoscopic screenshots.
fix a potential crash from frag parsing.
added m_accel_style and friends, for nicer mouse acceleration.
fixed const-correctness in a few places.
added friendly spectate button to the server browser
display a warning if an mdl has dodgy seam values. this won't affect fte, but can crash winquake.
qcc: fix struct fields to at least appear to work.
qcc: -I is finally implemented.
qccgui: options now has tooltips, so people might have a chance of actually figuring out what each option does.
menusys: game configs menu now scans for files rather than listing specific ones. should probably be tested more.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4998 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some issues with ezhud. ownfrags, text alphas, RGB player colours.
tweak gamecontroller input a little, to make axis slightly more usable.
fix issue with menuqc/csqc not being able to query binds reliably.
fix csqc gravitydir.
bump r_particle_tracelimit so that its no longer a limitation by default.
tweak fog to allow far-clip-plane culling on entities (but still not on world, due to issues with glClear).
fix performance issue with q1bspx BRUSHLIST lump.
fix mvd recording bug.
fix limitation that becomes apparent on maps with lots of ents visible at once. will now use more bandwidth in such cases, however.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4994 fc73d0e0-1445-4013-8a0c-d673dee63da5
tweaked cl_maxfps a little. now sticks much closer to the desired rate. also tweaked cl_netfps. clamps 77fps to 13ms frames (read: 76.9 fps) in an attempt to avoid tripping up any framerate checks (we had previously been using a lower net rate with occasional 14ms frames).
viewspace particles are now a thing.
greater control over spawning particles. its now possible to spawn particles only in slime, etc.
fix soundlength builtin.
preliminary version of r_dynamic -1, which can give some significant framerate boosts on certain maps.
fix halflife bsp texture issues.
rewrote worker thread logic. workers now work as a single pool, instead of independent pools. this means that you don't have to wait for a specific thread to finish before it can load new stuff, reducing overall load times some more. worker_count cvar allows reconfiguring the number of active workers. can be changed any time.
updated mod_terrain_create command. should be more useful now and make more sense when first loaded.
fix lit support. apparently its been broken for a while.
brush editor now has csg subtraction.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4990 fc73d0e0-1445-4013-8a0c-d673dee63da5
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
bind command now makes it a bit easier to edit the binding. and any alias.
autoid tweaks.
slightly better q1qvm/ktx support. extend the api a little.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4927 fc73d0e0-1445-4013-8a0c-d673dee63da5
added dimension_default global to provide default dimensions. expected to be a (var) constant.
support setcustomskin in menuqc.
implement some considerations for win95, so it can actually run on that horrendously outdated system.
provide scr_autoid and r_showbbox-field info when running csqc.
ignore vid_restarts at the end of config.cfg files from other engines. in fte, these are at best redundant and at worst overrides user settings.
fix issue with latched cvars not flagging the config as modified.
path command always shows filenames properly.
fix some fteqcc inlining bugs.
added precaches command to display all active precaches.
added docs for mapcluster.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4881 fc73d0e0-1445-4013-8a0c-d673dee63da5
Fixed openal linux .so name, now usable in linux.
sdl audio code now uses sdl2 audio, and thus can support multiple devices simultaneously.
linux non-sdl builds now dynamically link to SDL2 for audio. This is now the default audio system in ALL non-android linux builds. This is the only real option to cope with the mess that is alsa.
Fix netgraph when running q2. No longer makes palette assumptions.
Fixed q2 ping values.
Tweaked a load of windows code to use wide chars, because microsoft do not support utf-8.
fixed an issue with winsspi where data from large packets could get lost.
now tries to read .lit2 files (although still refuses to read them for now).
Fixed motionblur. To make Shpuld happy... :P
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4871 fc73d0e0-1445-4013-8a0c-d673dee63da5
fixed non-browser ogg decoding and openal logic. should finally be fixed, I guess.
wasted some time on an ezhud plugin, along with ensuring certain info is available to the plugin. this is still a work in progress however.
non-web builds are now able to download images from urls.
download progress does not display for uri_get/uri_post builtins, nor other non-saved things.
q1qvm logic now uses pr_maxedicts cvar. the gamecode api still provides no way to tell how many are permissable, so set at own risk.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4852 fc73d0e0-1445-4013-8a0c-d673dee63da5
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
tweak some dp compatibility things. probably futile.
moved ode to a plugin.
added screenshot_mega command to take massive screenshots that are not tied to current video mode.
removed offscreen-gecko code completely.
added cvars to rescale offsetmapping from paletted sources, so it can be disabled where its ugly.
added support for zip weak encryption. the password defaults to 'thisispublic'. nothing is fool-proof.
gl: fix stereoscopic rendering.
gl: fix rendertargets with depth.
qc: added support for named builtins that do not have any specific number.
qc: added some new builtins. drawrotpic, drawtextfield, search_getfilemtime, and a few others.
qc: PF_Fixme now attempts to figure out which builtin you tried to call, for more friendly fatal error messages.
qccgui: stepover and stepout are now implemented, as is setnextstatement.
qccgui: added a way to annotate code with the asm statements generated from them.
qccgui: fixed double-clicking a src file.
qccgui: handles multiple .src files more usefully.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4832 fc73d0e0-1445-4013-8a0c-d673dee63da5
net: revert the player angles inversion thing from last build. hack some angles. gonna need to tweak the protocol.
net: cl_lerp_players is smoother, and defaulted. lets see how many people complain.
cl: fix juddering with chase_active+prediction.
cl: download progress where the total size is not known now displays something more sane.
cl: fixed some issues with rawinput keyboards.
cl: added autoupdate option to the menu.
cl: autoupdate defaults to a new 'tested' set of builds, instead of the completely untested svn builds.
cl: added 'borderless windowed' option to the menus. works on windows.
cl: saved games save a preview screenshot.
cl: fix some memory leaks on shutdown.
cl: added 'setrenderer random' option, might be useful for modders in that it helps highlight bugs/differences between renderers...
qc: r_showbboxes now displays the fields of the various entities.
tweaked entity lighting to overbright more gracefully.
gl: fixed crepuscular lighting.
qcc: added % operator.
qcc: added inline keyword.
qcc: some fixes for accessors.
qccgui: now prompts for exe+basedir.
sv: added sv_specprint, ala mvdsv.
sv: stats now sent over the unreliable channel instead of the reliable one. this allows them to change more frequently.
sv: rewrote speedcheat detection. clients will be throttled instead of kicked. unresponsive clients will be simulated instead of freezing in mid-air.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4829 fc73d0e0-1445-4013-8a0c-d673dee63da5
allow skin files to force qw skin player colours.
qccgui now does a quick parse-only compile to see comments on globals, as well as populate file lists correctly with preqcc-style src. however, doesn't compile actual functions, so can fail to pick up function defs (will go to first prototype instead of the body).
try to fix seasick issue when viewing an fte-protocol mvd. needs testing.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4828 fc73d0e0-1445-4013-8a0c-d673dee63da5
gui debugging works with -dedicated. actual dedicated servers still not tested.
preliminary hack to support directly loading .map files without compiling. stable but buggy, not really yet worth using. attempted to rework entity lump parsing to work properly with threads.
reworked colour clears. gl_clear now clears *BEFORE* csqc is called. also, now also supports a range of colours. use 8 for black.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4818 fc73d0e0-1445-4013-8a0c-d673dee63da5
