increase xz memory limit
fix fseek/fsize to match definitions.
r_deluxemapping is more aggressive with regards to generating lux files on demand (but won't generate lit data at the same time).
fix webgl shader issues.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5071 fc73d0e0-1445-4013-8a0c-d673dee63da5
tweak rtlights a bit, to not bug out on The Waste's decals.
use compatibility glsl in order to get ftransform working for consistent vertex coords (still uses core if there's no fixed function stuff). this fixes z-fighting issues with rtlights.
Rework punchangles for greater compatibility.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5059 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
implemented identify+iplog stuff for nq users.
r_tessellation forces blinn tessellation on meshes. can also be specified manually.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5055 fc73d0e0-1445-4013-8a0c-d673dee63da5
some tweaks to try to make webgl more robust.
added r_max_gpu_bones cvar. defaults to 0 in webgl for now (64 otherwise).
fixed gles2+skeletal issue that was breaking webgl (note r_max_gpu_bones needs to be set to 32 or something for it to actually use glsl bones with webgl).
sound rates now internally use decimals instead of percents. because meh.
allow PEXT2_MAXPLAYERS and angle deltas in nq.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5052 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix misc bugs.
rewrote skeletal code to use gpu-friendly skeletal data for all skeletal formats.
add modelframecount builtin, to easily get the number of frames in a model.
integrate hlmdl a little better.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5031 fc73d0e0-1445-4013-8a0c-d673dee63da5
openal: doppler now applies to openal more consistently.
vulkan: vk_loadglsl cvar enables vk_nv_glsl_shader, with support for existing glsl shaders (still no permutations for now). needs !!samps stuff.
vulkan: r_renderscale now partly works. r_fxaa also works under specific circumstances. needs more work. still no bloom or projections stuff.
menu_download: got a few tweaks to improve it, including zips. I still want to handle engine updates with this stuff, but that can wait for later.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5008 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some non-ascii encoding.
generate placeholder 8bit mipmaps for gles2/webgl in case anyone tries using 'vanilla' rendering.
revamping the downloads menu.
fix particles needing a specific blend mode in order to use custom shaders.
added trace_bone_id globals for qc. untested.
try to fix ragdoll crash. failing that, at least prevent it from being a crash.
try to fix d3d11 black lightmaps issue.
add r_norefresh to d3d9+d3d11
skin composing can now use subpics.
vulkan now tries to properly detect supported texture formats, instead of assuming.
vulkan now has a cvar to configure which dynamic buffers should be staged or shared.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5006 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
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
isolated transfers a little.
added preliminary support for r1q2 and q2pro protocols (no zlib).
fixed some missing q2 hud configstrings.
fixed models attached to particles not appearing the first time around.
fixed halos appearing on {foo fullbright textures.
fix particle crash bug from missing particlecubes.
implement r_converteffectinfo (instead of r_importeffectinfo with r_exportalleffects) for convenience. also now more complete and more accurate.
loadfont no longer auto-allocates slot 0.
fix issues with r_dynamic -1
don't restart audio on vid_reload (only reload it). this fixes audio issues with capturedemo with gamedir changes.
fix possible crash from loading sounds during an audio reload/restart.
now listens on both ports 27500 and 26000 when running quake, by default. sv_port or -port args will override.
work around surfedge corruption in some instance of the slide4 map that dimman found.
attempt to nudge players to travel at at least 200qu when travelling vertically through portals. this should help alieviate gravity-induced stuttering issues.
fix nested function types used in conjunction with op_state. now assumes static within the parent.
optimise array indexes slightly.
fix issue with ptr[float].foo
fix some qcc bugs to do with implicit type conversions
fix a portal / angle protocol extension issue, so legacy clients can use portals, they just can't see the other side (nor predict them).
fix q2 victory.pcx issue at the end of the game.
use abort/sigabort instead of sigsegv on linux sys_errors. this should help get people to report stuff better.
reformat the nq server advertising to be more helpful.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4996 fc73d0e0-1445-4013-8a0c-d673dee63da5
added //it stuffcmd.
now parsing //wps stuffcmds for ezhud use.
rework worker threads a little so that the main thread is no longer guaranteed to be stalled at least once. This speeds up load times a little.
fix nq server player counts in the server browser.
fix switching from/to spectator mode from destroying frag counts.
tweak custom bf args a little.
fix issue with player names starting with char 0x80.
fix menu.dat not loading.
attempt to fix flush lag on windows.
some fixes for stencil shadows.
try to fix public builds not knowing their svn revision. this should fix autoupdates.
added global_gravitydir vector, for mods that want to be really weird. doesn't clear onground flags however.
reworked the status command a little to attempt to report bursts a little better.
fix multicasts missing in mvds issue.
fix illegible server message with dpp7 downloads.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4992 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
implement cfg_save_auto cvar, to replicated vanilla quake, ish. default off, obviously.
support for Q2RDF_IRGOGGLES (in combination with Q2RF_IR_VISIBLE). untested.
rework vectorvectors to be more predictable. v_right_z is now _much_ more commonly 0.
fix potential sound-related lock-up/console spam.
implement $colored_armor+$colored_powerup macros.
if command now copes with ' quotes.
fix crash on flushing q3bsps.
fix black bits with r_renderscale+cl_sbar 1
implement emulation for legacy q3 shaders when glsl is required. this is primarily for webgl right now, but potentially also useful with any gles2 port (fixme: still need to tweak d3d11 backend to support this too).
include scrollbar glyphs in the fallback font logic. this is primarily for download progress bars, especially with webgl.
don't try applying gamma to screenshots when using glsl.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4976 fc73d0e0-1445-4013-8a0c-d673dee63da5
allow providing a videomap shader as a cwindow background. because I can.
move all the tenebrae hacks over to only explicitly detected tenebrae progs.
small irc plugin update.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4969 fc73d0e0-1445-4013-8a0c-d673dee63da5
load times reduced slightly.
don't show autoid armour if they're dead. its just not relevant.
fix csqc staticsound builtin.
fix some shader leaks/double-frees in certain situations.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4960 fc73d0e0-1445-4013-8a0c-d673dee63da5
implement hardware cursors in d3d9+d3d11
fix crash from closing the audio menu in the webgl port.
make deluxemapping+softwarebanding require a vid_reload before anything happens. this solves missing textures until the user does it anyway.
fix scores+spectating issue. again. oops.
rename openal devices in the webgl port, so that it makes more sense.
remove glsl/hlsl parameter limit. this also fixes the final ie webgl issue (still gets half the framerate though).
fix some issues with bloom and waterwarp active at the same time.
attempted to give properish error messages from emscripten, despite emscripten hating me.
hack drag+drop into fteqccgui. I ought to make fteqw accept demos etc this way some time too.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4959 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix vbos not being used for skeletal animations (50->770 fps jump, yes, really. OOPS!)
so yeah, 7700% speedup there. lol... *sigh*
fixed update notification prompt not appearing by splitting menu key dest into emenu+gmenu. thus the prompt is no longer killed by menu.dat starting up.
fog command now displays a the extra params.
rewrote console char handling to support 32bit unicode chars. font code does not support more than 16bit codepoints still, however.
rewrote beam code in order to restore models on vid_restart. this solves a crash where they were invalid pointers afterwards.
revived old menu_media, because jogi wanted shuffle.
music now fades out for a sec when changing fake-cd-tracks.
music no longer abruptly stops when changing maps.
added fxaa support.
reworked bloom a bit. can now bloom further.
added r_renderscale cvar, for people that want supersampling (max 2), or subsampling for more speed or whatever.
$timer now favours cvars with that name, rather than the $time macro.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4942 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix issues with converted qizmo demos that appear to contain connectionless packets.
clarify some spam a little.
made demos menu re-open in the same path as before, with the same demo selected. still no mouse.
attempt to cope with gles2's potential lower attribute limit.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4939 fc73d0e0-1445-4013-8a0c-d673dee63da5
make sure demos freeze at the start, instead of reading everything out of the file while we're still loading content.
added a couple of lame 'list' commands.
added 'in' command.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4928 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
implemented hud_teaminfo_show ezhud element. _LOTS_ of hacks. ezhud needs updated engine.
fix issue with overly friendly prints.
handle svc_setinfo more gracefully, for the next time OMC makes a bug.
allow glsl to embed default values for float cvars, in case they're not already set. this can save some docs...
removed prints about "wad" "foo\", fixing a crash concerning just which print function to call.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4925 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
$diffuse can now sample animmaps correctly (although this only makes sense when using glsl or replacement shaders (read: rtlights)).
$fullbright now defaults according to the animmap too.
added reflectcube and reflectmask (the latter defaults according to map/animmap, the former needs to be explicitly stated).
fix d3d9+d3d11 renderers a little. needs much more work.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4868 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
automatic lightmap texture scaling to retain more performance on large maps.
r_clutter preliminary implementation should probably fix up the shader still.
CSQC_Parse_Damage implemented.
finally implement q2 inventory.
fix mixer overflow crash.
glsl can now use s_diffuse etc to force inclusion of a diffuse sampler/texture, meaning shaders don't need to include them.
fix issue with writeip
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4841 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
fix gles+q3bsp black lightmaps bug.
enable q3bsp support in webgl port.
enable uncompressed pk3 support even if zlib isn't available.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4800 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to handle mvd prespawning a little more generically, to enable support for vweps (when protocol extensions are active). also fix issues with mid-demo map changes, which can potentially affect qtv streams.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4795 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix occasional vid_restart crash.
fix dynamic rtlight memory leak.
tweak some gl robustness things, so we can throw away the gl context and restart video cleanly if the drivers decide to randomly crash us. grr. dodgy drivers/hardware are annoying.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4775 fc73d0e0-1445-4013-8a0c-d673dee63da5
hexen2 players now have colourmaps again. doesn't crash with rgb player colours.
hexen2 colour previews now work (as well as they did in actual hexen2, anyway)
fix possible issue with 'bad type - needs fixing'
color command now longer omits 0 values when displaying.
readded support for all hexen2 palette lookup types.
fixed some hexen2 image positions.
using premultiplied alpha for pics as an easy fix for hexen2's various ugly halos.
the checkerboard texture is back!
fix q1 maps that have more than 32k clipplanes.
new features:
when associated with mdl etc file extensions, now opens up the modelviewer. also potentially changes gamedir (this applies to bsps too).
multiplayer setup menu now supports selecting rgb colours (lower colour remains with the 14 team colours). press shift for the normal/hue colour selection instead.
attempt to use bgra for texture uploads by default where available. reimplement possible support for 16bit textures.
attempt to implement gamepad support for web port. untested, but should be completeish.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4764 fc73d0e0-1445-4013-8a0c-d673dee63da5
unified image loading code a little between renderers.
support switching worldmodel in csqc. also associated bugfixes.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4758 fc73d0e0-1445-4013-8a0c-d673dee63da5
added option for softer/wider lines.
attempt to use hardware cursors in windows. provide api for csqc to specify its own.
cl_downloads cvar blocks all automatic downloads.
QUAKETC: new compile-time setting. if defined lots of stuff will be disabled including built in menus.
remove spam from log files.
try to get the webgl port to complain a bit more reliably when webgl is not usable.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4738 fc73d0e0-1445-4013-8a0c-d673dee63da5
gles renderer can use fbos now.
webgl now saves configs+savedgames persistently using localstorage.
misc startup/manifest refinements.
make nacl compile again.
webgl port can now use #stuff to select different manifest files.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4733 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some compiler warnings.
update the emscripten port.
reduce bss a little (as emscripten blatently can't cope with it)
support for '_wateralpha'. also support for cvar_foo too.
demo_jump works in nq demos.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4732 fc73d0e0-1445-4013-8a0c-d673dee63da5
added r_part_classic_square, cl_demoreel.
fixed a couple of things that the ever vigilant gb spotted. I guess I don't play quake enough.
fixed a load of random warnings reported by gcc. many many many warnings remain. I got bored.
internal mrt feature implemented, not properly tested yet.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4719 fc73d0e0-1445-4013-8a0c-d673dee63da5
add the particle debugging commands to release builds too. probably should only be the particles one and not the trails one, but whatever.
try to do something about black screens on android etc by sys_erroring if we get glsl compile errors on the default2d glsl when there's no fixed function available. this is enough to ensure that the console text+background is always visible, or they know(ish) why its not.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4660 fc73d0e0-1445-4013-8a0c-d673dee63da5
reworked a few q2 particle effects. q2 should feel a bit better now. by no means complete.
ssqcless csqc should have time progressing.
q3ui+console should be a bit less stupid.
stripped old huffman code. copied over from ioquake3. should help avoid bugs in that shit.
system mouse cursor should now always be hidden when running windowed. soft-cursor only.
added bindlist.lst feature.
particle system can now support weighted/randomized sounds. model command now more verbose, and supports renderflags.
renamed debugger cvar to pr_debugger, in the hopes that it'll be easier to find. also added to menu a little more visibly in a politically-motivated move.
fix q2+viewsize 30
'high' particles now have scrag+hknight impact effects. perhaps I overdid the scrag one.
fixed q2 player icons on the scoreboard.
added q3bsp_surf_meshcollision_* cvars.
dedicated servers now use the same bsp etc loading code as clients. the dedicated-server-only stuff is no longer needed, which is a good thing because it seemed a little buggy last time I tried.
split vertex+fragment shader compilation, for systems that secretly thread that.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4651 fc73d0e0-1445-4013-8a0c-d673dee63da5
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.
