272a91f754 Merge of apricot branch game engine changes into trunk, excluding GLSL.
GLEW
====

Added the GLEW opengl extension library into extern/, always compiled
into Blender now. This is much nicer than doing this kind of extension
management manually, and will be used in the game engine, for GLSL, and
other opengl extensions.

* According to the GLEW website it works on Windows, Linux, Mac OS X,
  FreeBSD, Irix, and Solaris. There might still be platform specific
  issues due to this commit, so let me know and I'll look into it.
* This means also that all extensions will now always be compiled in,
  regardless of the glext.h on the platform where compilation happens.

Game Engine
===========

Refactoring of the use of opengl extensions and other drawing code
in the game engine, and cleaning up some hacks related to GLSL
integration. These changes will be merged into trunk too after this.

The game engine graphics demos & apricot level survived my tests,
but this could use some good testing of course.

For users: please test with the options "Generate Display Lists" and
"Vertex Arrays" enabled, these should be the fastest and are supposed
to be "unreliable", but if that's the case that's probably due to bugs
that can be fixed.

* The game engine now also uses GLEW for extensions, replacing the
  custom opengl extensions code that was there. Removes a lot of
  #ifdef's, but the runtime checks stay of course.
* Removed the WITHOUT_GLEXT environment variable. This was added to
  work around a specific bug and only disabled multitexturing anyway.
  It might also have caused a slowdown since it was retrieving the
  environment variable for every vertex in immediate mode (bug #13680).

* Refactored the code to allow drawing skinned meshes with vertex
  arrays too, removing some specific immediate mode drawing functions
  for this that only did extra normal calculation. Now it always splits
  vertices of flat faces instead.
* Refactored normal recalculation with some minor optimizations,
  required for the above change.
* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.
* Fixed various bugs in setting of multitexture coordinates and vertex
  attributes for vertex arrays. These were not being enabled/disabled
  correct according to the opengl spec, leading to crashes. Also tangent
  attributes used an immediate mode call for vertex arrays, which can't
  work.
* Fixed use of uninitialized variable in RAS_TexVert.
* Exporting skinned meshes was doing O(n^2) lookups for vertices and
  deform weights, now uses same trick as regular meshes.

b6a6507ddf getting ARB shaders working again in GE.
This is is a kludge, and only to get a release
working. later solution is to use glew

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

867e12836b This patch spawns from this game engine issue:
[#7113] GE crash pressing as soon as P on 64 bit


Note:         glext.h has been removed from the source
        If you get errors compiling with it you have 2 options
                download/install 	glext.h        (preferred method)
                or set WITH_BF_GLEXT=false
        If your a user and having problems with game engine try
                setting the env var: WITHOUT_GLEXT 1

a30dc3866c Some issues compiling on Irix:
+ the code in writemovie.c no longer compiles (since the renderer
refactor). I have #if 0-ed it.

+ OpenGL on Irix doesn't have GL_ARB_vertex_program

+ mmap on Irix doesn't like MAP_ANON.

+ If using the MipsPro 7.3 compiler, the variable MIPS73_ISOHEADERS
can be set to point to the directory with those weird C++ headers
that don't have .h in the name

e4790aef46 Improved OpenGL Shader Language support for game engine. The python interface is much simplified. Drawback is that scripts need to be updated next release. Testfiles:

77c4eef90b after much suffering, got GE build and work almost cleanly on Os X
(with make, need to confirm with scons)

after cleaning the changes are in fact minimal, but the situation
is still quite a bit hackish.

Game engine coders, there is also quite a number of warnings that
need to be fixed.

current situation is that everything seems to work, but GLSL shaders
spew a lot of errors on console and blender may crash on exit when
a GLSL shader was used. ARB stuff works fine.

2e6d576182 Sorry to break the cvs-closed status, so if you really need to make a new 2.40 build, just disable the game engine if it doesn't compile for a platform. Again, sorry if this breaks non-windows platforms, but I hope people help to get this amazing fix working for all platforms. Armature-fixing contribution from Snailrose. Also lots of cool things from Snailrose and Lagan.
Armatures are back
Split screen
Double sided lightning
Ambient lighting
Alpha test
Material IPO support (one per object atm)
Blender materials
GLSL shaders - Python access
Up to three texture samplers from the material panel ( 2D & Cube map )
Python access to a second set of uv coordinates

e926d392a8 OK, the game engine has been un-buildable on irix for long enough
-- I'm committing this change I had discussed on the mailing list
about a month ago.

00291b5cf4 [GameEngine] Commit all Kester's changes made to the gameengine to restore 2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them

That was about it.

There are a few things that needs double checking:

* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
