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.

- 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

- The code to disable desktop composition in Windows has been moved from start

"NVIDIA/Aero bug - disable Windows composition". It is enabled by default.

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.

Increasing the values of 3 constants that control how much space is reserved

There is a real-world case where increasing these constants is needed.
That case is when compiling Icy World for Urban Terror.

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.

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.

Rewriting BaseWindingForPlane() in polylib.c from the ground up. The behavior

Performance should be better as well (but that is not tested).
This is a major milestone because it fixes two regression tests:

Improvements to math precision is ongoing and more improvements can probably

This is a big big GTK file dialog change in Rambetter-temp-fixes branch.
Thank you to Markus Fischer who provided some example code on how to
use the "new" method of GTK file dialogs. I then did a lot of research into
how to shape his code into exactly what I wanted.
This is an incomplete change in that I have not cleaned up the code such
as removing unused local variables and unused functions yet. However, I
wanted to commit this now because it really works beautifully (the GTK file
dialog that is).
- In CFileType, m_pstrGTKMasks now contains string like
"quake3 maps (*.map)" instead of like "quake3 maps <*.map>". Nobody else
is using this code except in gtkmisc.cpp so it's a safe change.
- Removing all FILEDLG_DBG blocks in gtkmisc.cpp. It really clutters up the
code and since it's completely overhauled, it's OK to remove.
- Instead of the "old" way of gtk_file_selection_new(), now using
gtk_file_chooser_dialog_new() instead. Thx to Markus Fischer for examples.
- Actually adding GTK file dialog filters. It works really nice! :-)
- Now using the same file extension logic on Windows file dialogs and GTK
file dialogs.
- Improved file extension logic. "No file extension specified in file to
be saved. Attempt to save anyways?"
Tested on Win7 and Linux.
