The ultimate goal is to only allow the rasterizer to handle OpenGL and bf_gpu
calls. This commit creates a RAS_ILightObject interface and a RAS_OpenGLLight
implementation.
This mode is designed for passive 3D TV: the viewport is split
horizontally - left eye above, right eye below - but the original camera
viewport is squashed in each half (with half the vertical resolution).
This is necessary to restore the aspect ratio in the 3D output because the TV expands each half to the full screen size.
to support more than 2 UV maps. This code indirectly depended on the order of
OpenGL attribute ID's assigned by the OpenGL driver being the same as the
attributes being declared in the GLSL shader code, which is not always the case.
* Cleaning up the conversion code to avoid a per-face material conversion. Materials are now stored in buckets and only converted if a new material is found. This replaces some of Campbell's earlier work on the subject. His work wasn't as thorough, but it was much safer for a release.
* Shaders are only compiled for LibLoaded materials once. Before they could be compiled twice, which could really slow things down.
* Refactoring the rasterizer code to use a strategy design pattern to handle different geometry rendering methods such as immediate mode, vertex arrays and vertex buffer objects. VBOs are added, but they will be disabled in a following commit since they are still slower than vertex arrays with display lists. However, VBOs are still useful for mobile, so it's good to keep them around.
* Better multi-uv support. The BGE should now be able to handle more than two UV layers, which should help it better match the viewport.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
Summary:
========
The idea here is to move the texface options into the material panel.
For images with the change please visit:

1 - Some of the legacy problems 2.49 and 2.5x has with the texface system:
==========================================================================
1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can
select a face to be more than one mode.
1.2) Sort only works for blend Alpha yet it's an option regardless of the
Transparency Blend you pick.
1.3) Shared doesn't affect anything in BGE.
1.4) ObColor only works for Text objects (old bitmap texts) when using Texture
Face Materials. (not address yet, I so far ignored obcolor)
2 - Notes:
============
2.1) Now "Use Face Textures" in material Option panel will work in Multitexture
even if there is no texture channel.
2.2) In FaceTexture mode it will use TexFace all the time, even if you don't
check the "Use Texture Face" option in the UI. It's a matter of decision, since
the code for either way is there. I decided by the solution that makes the
creation of a material fast - in this mode the user doesn't need to mess with
textures or this "Use Texture Face" option at all. I'm not strong in my opinion
here. But I think if we don't have this then what is the point of the Texture
Face mode?
2.3) I kept references for tface only when we need the image, UV or the tiling
setting. It should help later when/if we split the Image and UV layers from the
tface struct (Campbell and Brecht proposal).
3 - Changes in a Nutshell:
==========================
3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set.
3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …).
3.3) New options in the Material Panel
* Shadeless option in the Material panel is now supported for all three Shading modes.
* Physics is now toggleable, this is the old Collision option.
* Two Side (on) is now called Back Culling (off).
* Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid).
* Shadow, Billboard and Halo are grouped in the “Face Orientation” property.
* "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually).
* The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties.
4 - Acknowledgment:
==================
Mike Pan for the design discussions, and testing along the whole development process.
Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that.
Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).
Blender artists that gave feedback and helped testing the patch.

---------------------------------------------------------------------------
The Rasterizer code was relying in the values defined on TF_ DNA files. I'm working in the recode of TexFace, bringing the options to the material panel and ran into those cases. They are hard to spot and add a lot of the "magic" effect to the code. Hardcoded values are at least easy to spot. We (still) have a few defines duplicated, relying on each other (a flag previously defined in the code is checked later on but using a different define (although with same value. (e.g. TF_BMFONT and RAS_RENDER_3DPOLYGON_TEXT). It's hell =)
I'm adding some comments to help on that.
Things will be revamped anyways, but it's nice to keep the code a bit more coherent before the real feature commit. That's all, thanks for listening.
- ignore MSVC warnings when FREE_WINDOWS is defined to quiet warnings.
- the CMake flags were not being set correctly making blender have weirdo colors (no -funsigned-char).
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.

Fixed two bugs from original patch:
- deleting a text will clear the warp field from Game framing settings
- removed spurious black dots along the edge of the cube map in the gameplayer
Known limitation:
- resizing of the screen doesn't work in the gameplayer
Known bugs:
- Texture with reflexion are not rendered correctly
- Spurious problems with light
vector in perspective mode. This is default OpenGL behavior, but
by now this optimization is really insignificant. Works in both
the 3d view and game engine.
* Fix issue with add transparency mode with blender materials.
* Possible fix at frontface flip in the game engine.
* Fix color buffering clearing for multiple viewports, it used
to clear as if there was one.
* Fix for zoom level in user defined viewports, it was based on
the full window before, now it is based on the viewport itself.
* For user defined viewports, always use Expose instead of
Letterbox with bars, the latter doesn't make sense then.
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
=======================================
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.
=============================
* 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.
