q3map2: bump MAX_OS_PATH to 4096
Fixes a "buffer overflow detected" abort when compiled with _FORTIFY_SOURCE=1.
The realpath(3) function in glibc checks if the destination buffer is large
enough to hold up to PATH_MAX characters and aborts if that is not the case.
PATH_MAX doesn't have to be defined so assume that it's equal to 4096.
We should really be using pathconf(_PC_PATH_MAX) instead of a hard-coded value
but that means we can no longer use static buffers to hold paths.

Switching order of picoModuleLWO and picoModuleOBJ as a quick

Removing optimization GCC flags because q3map2 crashes on Ubuntu 10.10 32 bit,

- Updated Windows build doc, very slight revision. Changed 37 targets to 38.
- Added plugins/imagehl to list of modules built (both Windows and Linux).
Not really sure what this does, but it's the only module (as defined by
stuff in plugins/ or contrib/) that exists and isn't currently part of the
build.
- The code to disable desktop composition in Windows has been moved from start
of main() to an option in Preferences. The pref reads as follows:
"NVIDIA/Aero bug - disable Windows composition". It is enabled by default.
- Color themes controlled by "Misc" -> "Colors" -> "Themes" options are now
saved as soon as you select them. The color theme is no longer clobbered
when opening Preferences.
- The ATI broken driver (bug #802) pref has been reworded since it applies to
Intel cards as well. Before:
"ATI cards with broken drivers - bug #802". After:
"ATI and Intel cards w/ buggy drivers (disappearing polygons)".

The release config for radiant target was busted on Linux in SCons build.
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.

This is a major change that updates the 3rd party libs on Windows builds.
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

Adding "Preferences" -> "Other" -> "Brush" tab. This now has
"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.

Turn off desktop compositing in Windows ("Aero") for Radiant.
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

can be used with Radiant.

Increasing the values of 3 constants that control how much space is reserved
for the stack and/or static memory for holding arrays of structures.
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).

Importing code changes for q3map2 from Rambetter-math-fix-experiments branch
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.

Undoing commits r363 and r371 as it pertains to polylib.c, mathlib.c,

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.

Undoing revision 377 (reverting just those files modified by that
