908337bee1 Game Engine: alpha blending and sorting
=======================================

Alpha blending + sorting was revised, to fix bugs and get it
to work more predictable.

* A new per texture face "Sort" setting defines if the face
  is alpha sorted or not, instead of abusing the "ZTransp"
  setting as it did before.
* Existing files are converted to hopefully match the old
  behavior as much as possible with a version patch.
* On new meshes the Sort flag is disabled by the default, to
  avoid unexpected and hard to find slowdowns.
* Alpha sorting for faces was incredibly slow. Sorting faces
  in a mesh with 600 faces lowered the framerate from 200 to
  70 fps in my test.. the sorting there case goes about 15x
  faster now, but it is still advised to use Clip Alpha if
  possible instead of regular Alpha.
* There still various limitations in the alpha sorting code,
  I've added some comments to the code about this.

Some docs at the bottom of the page:
http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/

Merged some fixes from the apricot branch, most important
change is that  tangents are now exactly the same as the rest
of Blender, instead of being computed in the game engine with a
different algorithm.

Also, the subversion was bumped to 1.

99fdf27af9 Sync with Apricot Game Engine
=============================

* Clean up and optimizations in skinned/deformed mesh code.
* Compatibility fixes and clean up in the rasterizer.
* Changes related to GLSL shadow buffers which should have no
  effect, to keep the code in sync with apricot.

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!

1f0ae739cb BGE memleak fix: OpenGL Display Lists not deleted when switching scene
This fix also improves performance of Display List for replica objects: Display List ID caching is now enabled for replica objects which avoids a tree search on each frame and for each replica.

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:

Make game engine materials use Zoffs in Materials.
Added Python material hooks.

90fb631526 Port a few rasterizer changes from tuhopuu2:
Up the max batch size.
Clean up some of the code - move code in headers to source files etc.

c9b4585618 Switch to using floats instead of shorts for normal data - they're supposed to be faster.
Also use shorts instead of ints for the index data, since index arrays are limited anyhow.

4c53f38756 Minor Fixes:
Better use of booleans for python
#include fixes for Windows
Python Doc fixes
Use the farthest vertex as the face position when z sorting faces. (Camera is on -z axis!)

e78ef29a59 Depth sorting for alpha mesh objects.
- Mesh Objects are sorted by depth (based on object centre.)  Using object centre means the user has control over the sort.
- Polygons are not sorted.
- Polygons are not split.
- O(nlog(n))

f03fa79d28 Fix for bug #945 getVertexArrayLength(x) returns different values on different runs of the game engine.
http://projects.blender.org/tracker/index.php?func=detail&aid=945&group_id=9&atid=125

The material buckets were being sorted by pointer (ie their location in memory.)

Also fixed find shared verticies.

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.

f1c4f705a1 Removed the config.h thing from the .h's in the source dir.
So we should be all set now :)

b9a19f1ea7 Did all of the .h's in source
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac

01bff70383 fixed spacing in the headers to get rid of some warnings and some other
little minor spacing issues.
