Cam's patch to enable parenting in the OOPS menu.

Fix for MSVC compiler. ;-)

Do a databrowse window for sound actuators when necessary.

Updates to GamePython Reference.
Added Actuator documentation.

new Object.select() and Object.isSelected() methods to manipulate the
selection state of Objects.
Contributed by Campbell Barton.

Fix for the IK Assertion bug when the IK constraint on a bone
points to the armature that owns the bone and the subtarget
bone for the constraint is invalid.

Thanks to Stephane Soppera for tracking this one down.

Use epydoc for generating game python reference (like the bpython guys)

Limit for Normalise() call was 0.000000001 or so. This is still far too
big, since a float can go to 10^-37. And, this value is still squared, so
a square root will not frustrate it.

Limit now is 10^-35, fixing disappearing faces in extreme small object
thats extreme close to a camera. (thanks OOPz!)

- added some "Transform Properties" for MetaElem (Metaball in edit mode, N key). It is locx, loxy, locz, dx, dy, dz and stiffness

Added Python module for Lights.
Added attributes to the vertex class.

Check for zero normal vectors in the clip planes (if eg Python has set a strange projection matrix)
Fix the transformation of the frustum bound sphere to world coordinates.

report #1338

Switched order of routines for displacement and autosmooth, where the
autosmooth will be last now. This prevents displaced (loose) faces, and
might give attractive sharp edges in other cases too.

bug #1340

Key alpha (render) set alph component at '1' for sky... this is an old
convention from NeoGeo days, and I have absolutely no clue whatfor...
maybe for some antique amiga iff format or so. Made it zero now.

Counter of mballs, before polygonize, had error in taking linked mball-
data into account, causing errors modeling.

Oh, the fix is an addition of a OB_NEG_SCALE flag in ob->transflag, which
is calculated in where_is_object.
Negative scale is found by a cross product of first 2 rows in matrix, and
comparing that (dot product) with third row.

NEW! Blender now displays flipped (negative scaled) Objects correctly in
OpenGL draw.

(BTW: the previous commit also solves raytrace errors with negative scaled
objects...)

Further a cleanup of displaylist flags and object/base flags. The #define
ACTIVE is moved to filesel.c (only used here).
The GONNA_MOVE #define got a OB_ added in front.

Recoded the methods how normals get corrected and flipped during render
conversion. Old method tried to solve it per object, detecting a flipped
matrix. Since we have displacemapping and raytracing this is too inaccurate.
Also, flipping normals should alsways result i correct flipped vertex-
normals too.

Solution is to completely recalcuate the 'puno' (vertex normal) flags in
renderHelp.c now (set_normal_flags). The face normals themselves are not
flipped until that stage.

Second major improvement involves the calculation of correct splitted
triangles, when a quad is not flat. It now creates triangles based on the
vertex normals, which have actual information on surrounding geometry, thus
resulting in much smoother results.
Without this you get errors in ray-shadow, with light shining almost
parallel to a face. But again, displacement mapping improves with it too.

Third fix is that by removing normal flipping from displace code the result
is much better now.

Bug fix 1332

EnvMap render now uses the percentage button for size (f10 buttons).
That wasn't implemented yet for saving envmaps....

Panagiotis Papadakos's patch to fix the following:

Implicit declaration of swab in Linux, needs to define __USE_XOPEN at
source/blender/src:

I also added #includst <stdlib.h> to this file to fix it on solaris as well.

Tom's additions to the windows build.
(I changed #blendersaue to #blendercoders not #blendercompilers,
does anyone actually use #blendercompilers?)
