Summary:
========
The idea here is to move the texface options into the material panel.

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.

- Use enum instead of back/front flags combinations.
- This flags behaves differently for 2d/3d curves so use different enums for them.
- This commit shouldn't change existing files.
- removed some unused functions.
- renamed vars to make more sense paint_vertex.c 'flags' --> 'lock_flags'
- some odd modifications were made in unrealted, commented code, copy these back from trunk.
- rename vertex_group_fix 'cp' property to 'accuracy'
- make style more consistant with trunk.
- remove 'Radish' comments.
- merge object.vertex_group_lock_all / object.vertex_group_invert_locks / "object.vertex_group_unlock_all into one operator.
- change lock button from a checkbox to a lock icon.
- move get_selected_defgroups & count_selected_defgroups into blenkernel
- split calc_weightpaint_vert_color() logic so its more obvious whats default and multipaint behavior
* The new NAVMESH Modifier did not show any buttons, console printed errors instead!
* Poll of "PHYSICS_PT_game_obstacles" panel caused errors as well, self instead of cls was used as argument.
* Check to show/hide buttons in "WORLD_PT_game_physics_obstacles" panel did not worked due to wrong ENUM identifier ('None' instead if 'NONE')
* Moved "SCENE_PT_navmesh" panel out of properties_scene.py into the properties_game.py where it belongs and renamed it. Also, don't use abreviations in Panel Headers (Navmesh > Navigaion Mesh)
* Code cleanup, removed unnescecary code.
* bpy.types.Panel > Panel
Add navigation mesh capability to the BGE, both by logic bricks and python.
Add tools to creation navigation mesh in the creator:
- manualy
- automatically from existing mesh with "object.create_navmesh" operator
- automatically from existing mesh with "Navigation mesh" modifier
Editing navigation mesh is possible via special modifier edit mode.
Creation and modification of Navigation mesh is also possible at runtime in the BGE.
Documentation at http://wiki.blender.org/index.php/User:Nicks/Gsoc2010/Docs
Warning: No upgrade is provided for blend files created under the branch.
If you load a blend with navigation data created with a branch
build, it will likely crash blender or behave incorrectly.
*Updated UI code (replaced “row columns” by splits ;) ).
*Clamped global influence to [0.0, 1.0] range!
*Added/edited some tooltips for Proximity.
*Proximity distance mapping can now be reversed by entering Lowest Dist > Highest Dist.
*Moved mapping before masking in Proximity, much more sensible this way!
- It's like sketch mode for lines, but you're specifying line knots
by clicking on position you want to add next knot.
- View can be navigated between knots creation.
- Holding LMB down and sliding mouse will lead to new segment preview
so it can be created more accurate.
Additional change: fixed GP->Bezier conversion. Last point used to
be ignored in this operator.
*Added Smooth/Sharp/Root/etc. mappings to WeightVGEdit modifier, in addition to custom curve one.
*Added Smooth/Sharp/Root/etc. mappings to WeightVGProximity modifier, without the custom curve one!
*Factorized the common mapping code into MOD_weightvg_util.
This patch adds:
* support for proxy building again (missing feature from Blender 2.49)
additionally to the way, Blender 2.49 worked, you can select several
strips at once and make Blender build proxies in the background (using
the job system)
Also a new thing: movie proxies are now build into AVI files, and
the proxy system is moved into ImBuf-library, so that other parts
of blender can also benefit from it.
* Timecode support: to fix seeking issues with files, that have
a) varying frame rates
b) very large GOP lengths
c) are broken inbetween
d) use different time code tracks
the proxy builder can now also build timecode indices, which are
used (optionally) for seeking.
For the first time, it is possible, to do frame exact seeking on
all file types.
* Support for different video-streams in one video file (can be
selected in sequencer, other parts of blender can also use it,
but UI has to be added accordingly)
* IMPORTANT: this patch *requires* ffmpeg 0.7 or newer, since
older versions don't support the pkt_pts field, that is essential
for building timecode indices.
Windows and Mac libs are already updated, Linux-users have to build
their own ffmpeg verions until distros keep up.
