52ab4f64f9 Add code for loading vertex colors. 
And correct an oopsie in bledweights.
 2012-05-15 21:08:44 +09:00
Bill Currie
215d2e9747 Add a function to decompose a matrix. 
The function gives rotation(quaternion), scale, shear, and translation (all
three as vectors), shear is (XY, XZ, YZ).

1be9384f10 Load the iqm vertex and triangle data. 
Still have the meshes, joints and animations to go.

8aabb704d2 Add tests for inverting a dual quad transform. 2012-05-15 21:08:43 +09:00
Bill Currie
f874aeb941 Add support for duals and dual quaternions. 
Not everything is unit-tested, but the currently important stuff is.

e6c0512f31 Ensure dstring has space for terminating 0. 
It seems (some versions of) windows vsnprintf don't count the terminating 0
when limiting the number of chars written to the buffer. Nor do they
guarantee the output string will be terminated.

0036a5e113 Ensure edict_size is never 0. 
Avoids division by / in NUM_FOR_EDICT

099d9ec3f2 Move the increment of order out of the loop. 
I don't know what gcc's optimizations would do with it, but it seems quite
reasonable to pull the code out of the loop by hand.

cf5c9f067f Make GL_DrawAliasShadow const correct. 
Despair's having troubles with segfaults that I can't reproduce. If it's a
strict aliasing problem, this might help.

a43bd755ca Fix the 32-bit x86 build of the software renderer. 
I really need to remove the sledge-hammer approach, but this at least gets
QF working out-of-the-box on 32-bit x86 systems.
 2012-04-28 13:02:36 +09:00
Bill Currie
8791b35e55 Add support for half floats. 
iqm and OpenGL use them, so they might come in handy. The tests use values
from wikipedia and a couple extra.

1a0ccf6a92 Add vec = quat * vec to the progs engine. 2012-04-26 11:58:20 +09:00

0a22a98b60 Fix some mis-versioned opcodes. 
Many of the quaternion opcodes were marked as being available for id progs.
oops

efaef89c5f Add a shortcut function for quaterion/vector multiplication. 
I got the idea from blender when I discovered by accident that quat * vect
produces the same result as quat * qvect * quat* and looked up the code to
check what was going on. While matrix/vector multiplication still beats the
pants off quaternion/vector multiplication, QuatMultVec is a slight
optimization over quat * qvect * quat* (17+,24* vs 24+,32*, plus no need to
to generate quat*).

7b0d48313d Fix a signed type mixup. 
I mis-applied calim's patch, and gcc failed to tell me :(
 2012-04-26 07:28:22 +09:00

20b7a46100 Remove a bogus model type check. 
This allows 16-bit alias models to render when viewd straight on.

ba7046ea09 Allow large skins in sw32. 
Dirty rotten magic numbers :P

866c56c236 Do not try to lerp entities when their model changes. 
This avoids sending invalid pose data to the renderer. The symptom was a
vertex array offset higher than the vertex array size. Discovered by calim
of nouveau while he was debugging a driver problem found by QF. Many
thanks.
 2012-04-25 10:09:23 +09:00
Bill Currie
a7870a98a1 Apply a couple of patches from calim of nouveau. 
One's an actual bug, the other a bit of error checking (not sure how
necessary it is, but it's in code that we don't /want/ to run, so it can't
hurt :)

e167300a84 Fix a segfault in the sw32 renderer on entering e1m7 
While this particular tigger of the real bug was caused by 659d95221e
(hopefully fix both the "get stuck waiting for 3d" bug and the null
worldmode bug.), the real bug was lurking in the code since the dawn of
time (from sw32's perspective). This fix is as per LordHavoc's suggestion
(heh, despite the years, he knows his code), but I spent the time hunting
down the trigger to understand just what was going on.

It turns out that (0,0,0) is too close to a wall (probably on, but the
slight default offset is too close) and the above commit changed the first
rendered frame to be before the player origin was set rather than after.
This fix feels correct to me because noclipping around with the sw32
renderer would probably hit the same bug with a bit of bad luck. Thus
ensure the index resulting from zi never exceeds 65535.

bc1b483525 Nuke the rcsid stuff. 
It's pretty useless in git.

1fd84477a2 Rename char to dchar in the text vertex shader. 
Thanks to Spirit :)

Turns out certain drivers (nvidia?) reserve "char" even though opengl does
not. This should fix his missing console text.
 2012-04-21 20:59:04 +09:00
Bill Currie
3b07928373 Fix an inconsistent numeric constant. 
While checking the shaders to see if there might be anything obvious to
work around the current nouveau shader issues, I found a 1 that should have
been a 1.0. I'm surprised it ever compiled.
 2012-04-20 16:30:25 +09:00

561484842c Fix some snafus in PL_ParseData 
Found them by inspection while writing a python version of qfplist.

6f026e9116 Fix some segfaults in server model loading. 
I'd forgotten to test the servers when I did the vid_plugin changes.

bbd277cb72 Fix building libQFrenderer as a helper library. 2012-04-12 17:16:40 +09:00
Bill Currie
61ae793367 Fix two broken symbols for sw32. 
Now all 4 render plugins load as standard plugins (though there's still a
problem with libQFrenderer.so)
 2012-04-12 17:12:24 +09:00
Bill Currie
633f70b2f1 Remove a functionally dead symbol. 
The only purpose clearnotify seemed to be serving was to stop the console
plugin from loading :P
 2012-04-12 17:05:42 +09:00

7fc99f9c60 Fix gl and glsl support in sdl. 2012-04-12 16:47:37 +09:00

ab486dcdf6 Unregister the quit command before registering it. 
This fixes the quit menu not working.
 2012-04-12 15:07:28 +09:00
Bill Currie
e784754a11 Disable the gl_triplebuffer check in glsl. 
It doesn't seem to have any useful effect in QF (even before the plugin
project) other than setting the number of frames to update. I'm not sure if
it's a useless variable or one where the user is supposed to match it to
the system configuration. Anyway, with this, the glsl plugin now works.
 2012-04-12 14:40:02 +09:00
Bill Currie
8401704c4e Connect up palette setting for gl and glsl. 
The GL plugin now seems to work. GLSL still segs :(
 2012-04-12 13:57:05 +09:00
Bill Currie
525dbcc13e Ensure code paths stay within the one renderer. 
The gl renderer calling sw functions is bad news. Still all black, but I
think that's because palette setting is disabled.
 2012-04-11 22:45:23 +09:00
Bill Currie
898bfa5e5f Split up the vid plugin init sequence. 
This gets gl so it no longer segs. However, the screen remains black
(expect for cshifts).
 2012-04-11 16:44:38 +09:00
Bill Currie
6ff658afe4 Use r_funcs in the client console plugin. 
Getting the sw renderer's functions when running gl was nasty.
 2012-04-11 16:38:15 +09:00
Bill Currie
d62772e9cc Separate render module loading from initialization. 
This allows the vid module to load the render module and access render
specific functions before the renderer initializes, which happens to need
an initialized vid module...
 2012-04-11 14:58:56 +09:00
Bill Currie
799a0ae018 Fix a bogus cshift calculation in sw32. 
Found via valgrind and gammatable having become malloced instead of static.
 2012-04-11 14:58:55 +09:00
Bill Currie
07ab5600c9 Recache viddef in *D_InitCaches. 
sw32 now at least doesn't seg, but doesn't draw any 3d. sw renderer seems
to work.
 2012-04-11 14:58:55 +09:00
Bill Currie
42868d308e Initialize the skins and particles subsystems. 2012-04-11 14:58:55 +09:00
Bill Currie
6ea4e6617a Connect up viddef properly. 
Or mostly so, anyway. sw32 is actually putting stuff on the screen.
 2012-04-11 14:58:55 +09:00
Bill Currie
4d9c3408a1 Start putting the pieces back together. 
The renderer now gets initialized and things sort of work (qw-client will
idle, though nothing is displayed). However, as the viddef stuff is broken,
it segs on trying to run the overkill demo.

f5d6959f4b Copy out the model functions pointer. 2012-04-11 14:58:55 +09:00
Bill Currie
6f7b4276e9 Move VID_InitBuffers back from the renderer to targets. 
First, it was nearly identical between sw and sw32 (one paranoia line in
sw32), and second, it's common enough.
 2012-04-11 14:58:55 +09:00
Bill Currie
a093e6af97 Move palette setting into viddef_t. 2012-04-11 14:58:55 +09:00
Bill Currie
e08d5ccb41 Move the gl util functions into viddef_t. 
Static plugins almost link now, just two more symbols to sort out.
 2012-04-11 14:58:55 +09:00
Bill Currie
7ed33f6345 Hide D_FlushCaches. 
There'd been a way to do so all along :/ There might be some issues with
this, but those will be easy to fix :)
 2012-04-11 14:58:55 +09:00
Bill Currie
7865f6afe1 Rename sw's R_Init to sw_R_Init. 
For now, the only symbol I'll bother messing with in the sw renderer.
 2012-04-11 14:58:54 +09:00
Bill Currie
1dd1aec48f Make libgl_handle static. 
This will make life interesting for getting the final stages working, but
it helps for now.
 2012-04-11 14:58:54 +09:00
Bill Currie
772af29cb3 Move the gl cvars into gl. 
That gets rid of the gl_overbrite_f clash. They were put in r_cvar for
saving to the config file, but that was before seta existed.
 2012-04-11 14:58:54 +09:00
Bill Currie
65bd29353c Make a start on putting the pieces together. 
Still many undefined and multiply defined symbols, but there seems to be a
light in this darkness. I just hope it's not an oncoming train :)
 2012-04-11 14:58:54 +09:00
Bill Currie
d445b4ef88 Rename the glsl qfgl functions to qfegl. 
Keep them separate from the gl renderer :)
 2012-04-11 14:58:54 +09:00
Bill Currie
36504547a8 Rename the public symbols for gl, glsl and sw32. 
Evil hack, but it does the job.
 2012-04-11 14:58:54 +09:00
Bill Currie
8de5c9ae3f Do a final cleanup before doing the big rename. 2012-04-11 14:58:54 +09:00

f7007825e4 Run the vacuum cleaner over sw32's global variables. 
This seems to be everything that can be made static.

eb536dc995 Remove D_BeginDirectRect and D_EndDirectRect from gl/glsl. 
They were never really needed anyway (they're for the sw renderer).
 2012-04-11 14:58:54 +09:00

e991c1fed3 Make a bit of progress cleaning up vid for plugins. 2012-04-11 14:58:54 +09:00
Bill Currie
80f5cc59e9 Plug a memory leak. 
Allocating (and not freeing) rects every frame... ouch.
 2012-04-11 14:58:54 +09:00
Bill Currie
96b80433d8 Make some progress in getting static plugins to link. 
Still many redefined symbols (and I expect more to come), and many
undefined symbols too.
 2012-04-11 14:58:54 +09:00

8530959752 Link the model libs to the render plugins. 2012-04-11 14:58:53 +09:00
Bill Currie
8e91fb7bc1 Get the basics linking. 
Still, nothing will work: no plugins are loaded and they're all broken
anyway.

glx, sgl, glslx etc are going away, just the basics will be built: fbdev
(probably go away eventually), sdl, x11 and hopefully someday win. That's
actually the only reason anything links.
 2012-04-11 14:58:53 +09:00
Bill Currie
a4c280f2b2 Take the first step towards render plugins. 
No clients link. Even if they did, nothing would work.

1cbabf72c9 Fix a buffer overflow. 
gcc 4.7 found it :)
 2012-04-11 14:56:49 +09:00

39e1ccc506 Don't try to process skins in GL without a player model. 
If the client receives a skin updated message from the server before having
loaded the player model (shouldn't happen, but some servers have very
strange programmers), no skin data is avaible for updating, so just bail
out.
 2012-03-14 16:08:48 +09:00
Bill Currie
82679066cc Run a vacuum cleaner over the diffs between x11 and glx init. 
X11 and GLX init are nowhere near as scary as I thought they were, once
they've been tidied up.

72fb96245f Cleanup global symbols for the sw and sw32 renderers. 
Names not mangled, but those symbols that could be made static have been.
Also, many dead variables have been removed.
 2012-02-18 14:34:14 +09:00
Bill Currie
ef37ed39a9 Clean up global symbols for the glsl renderer. 
Where possible, symbols have been made static, prefixed with glsl_/GLSL_ or
moved into the code shared by all renderers. This will make doing plugins
easier but done now for link testing. The moving was done via the gl
commit.
 2012-02-18 11:48:52 +09:00

447ff2f2f5 Clean up global symbols for the gl renderer.

057da55385 Fix the incorrect linkage of libQFrenderer* 
They're now currently not installed, but they were still building as shared
libs, and thus the installed bins were broken.
 2012-02-18 11:46:46 +09:00
Bill Currie
78789a6833 Add support for blender's environment maps. 
QF will now load a single image with (${skyname}_map.*) using blender's
layout. That is, 3x2 with the top row being back, right, front and the
bottom row being bottom, top, left.
 2012-02-16 20:47:38 +09:00

bfdb2b20d5 Clearify skybox layout.

ce6ab908a5 Don't include the specific plugin headers in plugin.h.

3cb4cb59b5 Link QFgamecode directly into QFruamoko. 
First step in the library "merge down".

QFgamecode is now a convenience library. The only things that mention it
directly now are ruamoko and qfcc.

9a91aff93c Move the ambient level check out of the sound renderer. 
Instead, the client gets the current leaf and passes ambient_sound_level
from the leaf to S_Update.

Bill Currie
d8a37bc791 Correct the usage of gzFile. 
Thanks to spirit for pointing that QF wasn't compiling with zlib 1.2.6
(archlinux, not yet in debian).

I was using gzFile as "gzFile *gzfile", but gzFile is already a pointer. In
older versions of zlib (including the 1.2.3 that's in debian), gzFile is
declared as a void *, and it seems that gcc is happy with assigning void **
to void *. However, in recent zlib, gzFile is now struct gzFile_s *, which
gcc is most definitely unhappy about assigning to struct gzFile **.

I just hope that either I had misread the type back when I wrote quakeio,
or that nobody is using such an ancient zlib.
 2012-02-13 09:00:31 +09:00

02d24189ef Use QF_NEED for plugins. 
At the moment, the selection of the default sound driver etc is broken.
 2012-02-12 11:37:25 +09:00
Bill Currie
4707706f5d Use QF_NEED for the renderer and model libraries. 
This breaks RPM building, but I can fix that later.

7a8f91edda Move bi_gib.c from ruamoko to gib. 
This makes gib depend on gamecode, but removes the dependency on gib from
ruamoko. Unfortunately, carne now needs to be linked against gamecode even
though it never uses it.

e34f0178b6 Build GLSL clients for SDL. 
Just about to do a release, and I realized windows users wouldn't have any

8ecf74753c Refer to local libs without a path. 
I'm sure I've been here before... Anyway, using $(top_builddir)/... to

9fbff2f4d5 Do an audit of the Makefile.am files. 
o All instances of LIBADD/LDADD have a corresponding DEPENDENCIES
    specificatiion.
  o libraries now use a lib_ldflags macro to keep things consistent
  o duplication of source/lib names has been minimized (particularly in
    the libraries; more work needs to be done for the executables)

c98ffa4eda Create a message buffer API for Ruamoko 
The api hides all the gory details of message buffer setup and usage

all wrong.

Thanks to "Sander van Dijk" <a.h.vandijk@gmail.com>, we now have much
better SDL sound support.

Here's the promised cleaned up version of the "double buffer" approach
patch for "snd_sdl.c". I've taken some more time to re-read and test
it this time, and it seems to behave well. All memory that is used by
both the main thread and the SDL audio thread is prefixed with "shm_",
and locking is used to ensure that only one thread accesses it at the
same time.

1229d24ef6 Get world rendering mostly working. 
Just some problems with lightmaps. There also seem to be some issues with
seams (t-junctions?) and far clip, but they're quite separate.

There's also a problem with a segfault when loading a second map.

6f18035c12 Fix up alias-16 support. 
After getting in contact with serplord, I now know that the sw alias
loading was correct. Turns out the gl loaders was mostly correct, just a
mistaken subtract rather than add. And with that, I can implement alias-16
support in glsl. better yet, since all the work is done in the loader, the
renderer doesn't know anything about it :) However, I need to create some
16-bit models for testing.

It's not perfect (it can't be), but it looks a whole lot nicer than no
interpolation.
 2012-01-04 18:31:35 +09:00

f0e88bbe85 Rip out the duplicate lerp code and merge it. 
While the vertex lerping needs to be duplicated in the current GL code,
there's no need for the setup code to be duplicated. Also, I want it for
GLSL.
 2012-01-04 16:26:52 +09:00
Bill Currie
99381b8b8c Rework the alias vertex shader and rendering code for lerping. 
Lerping isn't actually done yet (need to get both poses and blend), but
this still renders correctly with blend forced to 0.0.

Bill Currie
add5440ad1 Upload the normals with the vertex data. 
Not all hardware can access a texture sampler from the vertex shader, and I
don't want multiple paths this early in the game. Now, vertex normals are
uploaded as shorts. Should be 14 bytes per vertex (was 10, could have been
8 if I had put the normal index with the vertex rather than st).
 2012-01-04 09:42:00 +09:00

091b714e4c Implement dynamic lighting. 
This uses the same calculations as the software renderer. However, as the
lightmap calculations are not done yet, if there is no dlight in the
vicinity, there will be no light. demo1 is pretty cool to watch :)
 2012-01-03 20:36:07 +09:00
Bill Currie
209c4cda8b Scale the light level index correctly before colormap lookup. 
With this, lighting seems to be working. I'm not certain the normals are
100% correct, but I can see something happening on rotating models.

I spent way too long trying to figure out why triangle order wasn't making
any difference... :P
 2012-01-03 18:08:01 +09:00
Bill Currie
1437cbec91 Make the face culling a little more sensible. 
GL Quake was weird, culling front faces. Partly understandable, since
Quake's front order is clockwise and GL's default order is
counter-clockwise. However, since the order can be specified, that should
be done instead. Thus, specify the winding order as clockwise (for quake's
data), set culling for back-face removal, and then mess with the winding
direction in the mirror and fish-eye code.
 2012-01-03 18:06:26 +09:00

ba04cf73d0 Add my test tetrahedrons. 2012-01-03 09:34:17 +09:00
Bill Currie
baab15279f Correct the alias vertex data types. 
Vertex locations need to be unsigned byte rather than byte (GL is funy
with that). s and t need to be at least short, and since the normal index
is embedded in the st vector, it needs to be the same type. With this, my
test tetrahedrons seem to be working.
 2012-01-03 09:34:17 +09:00

55e53b796d Make a start on getting sprites rendering. 
The plan is to do interpolated sprites based on a discussion I had with
LordHavoc about them: blending between the two sprite frames. He didn't

necessary too.

e69a583f1b Work around a bug in mesa. 
Since I'm not specifying the api when creating my context, mesa is giving
me GL2. This is fair enough, but in GL2, vertex attribute 0 is the vertex
position. This too, is fair enough. The problem is, mesa is assigning 0 to
my vcolor attribute and thus I can't set it. The work around is simply to
swap the declaration order of vcolor and vertex (this really shouldn't work
eiter, I suspect).

The links are now in "instance surfaces". For non-instanced models (world,

instance surface per model surface. However, for instanced models (ammo
boxes etc), there will be many, dynamically allocated (not yet
implemented). This commit gets the static instance surfaces working.

3eb859a88f Move the entity transform setup into the clients. 
This has several benifits:
  o The silly issue with alias model pitches being backwards is kept out
    of the renderer (it's a quakec thing: entites do their pitch
    backwards, but originally, only alias models were rotated. Hipnotic
    did brush entity rotations in the correct direction).
  o Angle to frame vector conversions are done only when the entity's
    angles vector changes, rather than every frame. This avoids a lot of
    unnecessary trig function calls.
  o Once transformed, an entity's frame vectors are always available.
    However, the vectors are left handed rather than right handed (ie,
    forward/left/up instead of forward/right/up): just a matter of
    watching the sign. This avoids even more trig calls (flag models in
    qw).
  o This paves the way for merging brush entity surface rendering with the
    world model surface rendering (the actual goal of this patch).
  o This also paves the way for using quaternions to represent entity
    orientation, as that would be a protocol change.

51aaee5c3b Put that OpenGL error message to rest. 
The error was quite valid: setting GL_TEXTURE_MAX_ANISOTROPY_EXT to 0 is
incorrect. The problem was caused by the call to glTexParameterf being
before the gl_anisotropy cvar was initialized. Thus, move all of the setup
code in GL_Init_Common() to after all the checks and, more importantly,
after the call to GL_Common_Init_Cvars().

14d8e8669f Rework the legacy bind/unbind commands. 
in_bind_imt is now gone. I guess mercury was right in that it was a poor
design. However, it was (and still is necessary) to support "bind" and
"unbind". Now, instead, they work only with the IMT_MOD table. IMT_MOD sits
below IMT_0 in the imt hierarchy. If the key is not bound in IMT_0+, then
IMT_MOD will be checked. This way, "bind" and "unbind" can never mess with
a user's more sophisticated binding setup.

d9d56760e1 Add cvars to control the keys for menus and console. 
The backquote is not always usable for toggling the console, and the new
bind system doesn't automatically bind a key to both game and console imts
(by design). Thus create a cvar that allows the "always works" console
toggle to be specified in eg $fs_globalcfg. While I'm at it, do one for the
menus, too.

45288a1a7f Fix the ghastly sound quality. 
Due to quake's original sound engine using a push model, the actual place

Thus, the correct output location is indicated by snd_paintedtime rather
than snd_shm->framepos.

4f13d19b7e Optimize edges_intersect(). 
I found wolfram's line-line intersection page and noticed their equation
for the time of intersection was rather different to mine. After analyzing
the differences, it turns out they produce exactly the same results (when
the lines are coplanar), but their method allows me to eliminate one dot
product (4->3). Not only that, but it turns out that their method works
equally well for skew lines (ie, non-coplanar).

8fe703d747 Trace to adjoining leafs when necessary. 
When the trace stradles a plane in the current leaf, check the other side
of the portal, too, as it is possible that leaf will restrict the movement
of the trace.

already have a solution) where things will fail, but that's next.

9a9079a2b3 Correct the start-solid in a corner test. 
It turns out that the box trace CAN get out of the solid from that location
(though a similar point trace can not). This is because of my decision to
allow non-points to touch a plane from either side without crossing the
plane, whereas a point touching a plane is always considered to be on the
front side of the plane as there is no further information to disambiguate
on which side of the plane the point is.

4419d4c4ad Move the trace into the leaf before testing the contents. 
The trace is moved as far into the leaf as possible without leaving the

plane getting, but this has cleared up all the current contents related
tests.

f9d56f2941 Add MOD_HullContents(). 
If trace is null or point type, or the hull doesn't have portals, or the
first node is a leaf, MOD_HullContents operates in point mode (exactly the
same way as SV_HullPointContents()). However, in box mode, all leafs
touched by the trace are checked for their contents. The contents field of
trace (a bit field) will indicate the contents type of all touched leafs.
The returned contents value indicates the most important contents:

    solid > lava > slime > water > empty

The one's complement value of the contents type is the bit number of the
contents bit field. I'm not sure how useful this will be as getting the
amount of overlap is currently not supported.

750b5ba0ed Be a little more lenient with float comparisons. 
Unfortunately, Pythagorus and binary don't play well together, so rounding
errors are inevetible when testing with a slope. However, 1e-6 seems to be
a good epsilon (printf's %g hides it nicely :).

73b93ffd74 Clean up the in_leaf test line. 2011-11-28 20:54:35 +09:00

e3d8394b7a Use the split_plane for the in-leaf test. 
This seems to work better (all previously working tests pass again), but
the target test is still broken.

7b59eaf0cd Use the correct vector for the plane distance. 
Oops :)

cde0bbb807 For now, don't use box clipping for point traces. 
Until I figure out how I want to handle zero sized boxes, don't test them.

fd5aee1d5e Use the portals to check leaf validity. 
If the trace hits a portal on the plane that brought us to the leaf, then
we actually are in the leaf (otherwise, we shouldn't be here and thus
should ignore the leaf). At least, that's my thinking.

Many point tests fail (but they're really using box clipping with a zero
sized box) and two box tests fail.

Oops. Yay, valgrind.

d61cb25a44 Add code to rebuild the bsp brushes. 
Names and locations of declarations are still up in the air, but things
seem to be working assuming my test code is correct.

91e65b6c80 Rename mplane_t to plane_t and clean up the mess. 
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.

2f23cfa4d0 Add a new (failing) test case. 
This one demonstrates the need for more information in the bsp tree
(surface polygons). When the box collides with a corner where one side is
flat and the other angled, but there's a partition plane cutting the two,
the box can instead collide with the angled side before it hits the corner.

a943cdf2c4 Handle dual collisions. 
When the trace collides with something on both sides of a plane, the nearer
collision is required. The code now correctly checks both sides and keeps
the nearer collision.

0cf5dec5bb Fix the covered step tests. 
However,  there is still a problem with moves where the box is always cut
by the plane: both sides need to be tested (done), but when the first side
checked allows longer motion than the second, but still collides, only the
first side is checked. The shorter motion is required.

8cc320b7ef Move the start point to the near side of the crossed plane. 
I'm not sure the end point needs to be moved at all, but I'll leave it
alone for now. I have a couple of failing test cases that seem to be caused
by not handling moves where the box is always cut by the plane.

fa6390a46a Correct the sign for the shift in frac. 
However, this is not entirely correct as the new start point when testing
the other side of the plane also needs to be calculated.

b82d9f5894 Another test, another bug. 
Fix an incorrect test using offset (forgot to negate).

9984a2e87a Fix some missing usages of offset. 
This fixes my one failing box clip test. Now I need to find more broken
cases. At least now, they should be real tests.

9d63298032 Tweak a fixme comment. 
The code is potentially slow, especially on big maps, but I haven't noticed
any issues yet.

Not that boxes work yet, but the fix is the same.

I even have a failing test to fix :)
