Problem was that the compile flags were overly aggressive and caused segfaults.
They included: -O3 -Winline -ffast-math -fno-unsafe-math-optimizations
-fno-strict-aliasing
Changed to: -O2 -fno-strict-aliasing
From my experience, -O3 is usually a bad idea.

A couple of things are broken right now:
- OpenGL font in Windows not appearing (expected to be broken, will fix)
- Linux build broken because it loads some .vcproj files that are removed
- 3rd party libs are downloaded from porky.nerius.com, not id Software

I didn't realize they were so broken.
The fix is safe and should not break plugins or anything else.

"Default texture scale:". (Preferences are game specific by the way.)
The default value for this preference is specific to a game, but most
of the time it's 0.5. This field allows the user to override that default.
This is a feature that was specifically requrested by someone who wants to
try using ZeroRadiant (he wants to set it to 0.25 for his "premium" maps).
It's already a feature in NetRadiant.

is made, or it must be explicitly downloaded before the build.

Otherwise, "hall of mirrors" effect takes place in the OpenGL viewports.
This fix is a real hack. It's actually borrowed from other Radiants such
as NetRadiant. I'd like to fix the underlying issue someday so that Aero
can be used with Radiant.

in there, and it's active if MATHLIB_VECTOR_NORMALIZE_PRECISION_FIX is 0.
Right now it's 1, so the fixed code is active. I need this quick way to
test regression tests.

MAX_ORIGINAL_EDGES changed from 0x10000 to 0x20000 (x2 increase).
MAX_MAP_BRUSHES changed from 0x8000 to 0x10000 (x2 increase).
MAX_MAP_DRAW_VERTS changed from 0x80000 to 0x100000 (x2 increase).
This is pertaining to q3map2 only.
There is a real-world case where increasing these constants is needed.
That case is when compiling Icy World for Urban Terror.
Besides that, increasing these does not hurt anything (other than requiring
more memory).

Sure enough, they expose the "problem". I just created these based on my
understanding of the code and seeing a potential problem.

into trunk. Right now all the new code that fixes problems is turned off.
There are three new #defines in q3map2.h:
EXPERIMENTAL_HIGH_PRECISION_MATH_Q3MAP2_FIXES, EXPERIMENTAL_SNAP_NORMAL_FIX,
and EXPERIMENTAL_SNAP_PLANE_FIX. All of these are currently set to 0, which
means don't enable that new code. You can easily edit these to be 1 in order
to enable the new code.
There are very very minor changes to the code even with these three #defines
disabled. They are as follows.
- In PlaneEqual() in map.c, now considering deltas equal to given epsilon
values as "far enough to be different". Previously, the '<=' operation was
used, now '<' is being used.
- In FindFloatPlane() in map.c, considering delta equal to distanceEpsilon
(for plane distance) to be sufficiently far away. Before, delta had to be
strictly greater than distanceEpsilon.
- VectorNormalize() in mathlib.c is more accurate now. This change itself
causes at least one regression test to succeed. The previous implementation
of VectorNormalize() caused excessive errors to be introduced due to sloppy
arithmetic.
Note, the epsilon changes account for the possibility that the epsilons
are set to 0.0 on the command-line.

and mathlib.h (the regression tests have not been removed).
Trunk is now restored to a state that it was in before I started
trying to fix the math accuracy errors in q3map2. Commits r363 and
r371 were "correct" and did improve math accuracy significantly, but
unfortunately the underlying cause of math accuracy issues is something
else, which is being addressed in branch Rambetter-math-fix-experiments
currently. I'm taking the BSD approach here, which is "we not going to
partially fix the problem. it's all or nothing". Otherwise it's just
too risky in my opinion. I don't like playing Whack-A-Mole.
Someday, we might merge Rambetter-math-fix-experiments branch to trunk.
Sorry about all these needless commits to trunk.

commit). I have disovered the fundamental problem to the math error problems,
and although this commit (r377) is "correct", it fails to address the
fundamental problem. Therefore, I'd rather leave the code in a state that
has the exact same behavior as before until I get a chance to address the
fundamental issue.

examined yet, which is the plane intersection code. I want the errors to be
much less than they are now, even though the disappearing_sliver* tests are
now working.

the approach that was committed in r375 (but was then backed out). I can't
believe my eyes, but I seem to be getting 0.000000% error in some of my
regression tests. The trick is to scale by a power of 2 and never do a
VectorNormalize().

VectorSetLength() which contain floating point multiplications. Behavior
of BaseWindingForPlane() has been verified against base_winding regression
test (comparing output w/ logging patch).

is totally unchanged, and I verified this by running extensive tests. The
only difference is that the math precision is much much better now.
Performance should be better as well (but that is not tested).
This is a major milestone because it fixes two regression tests:
disappearing_sliver2 and sparkly_seam.
Improvements to math precision is ongoing and more improvements can probably
be made even after this patch.
I will update the README.txt files in the regression tests in a separate
commit. This commit only includes the actual fixed code.
