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.

Ending localview - which is similar to layer change - should send
update similar to change layers too. Needed for example when loading
a file saved in local view or when changing time in localview.
some functions had vague names, I even ended up re-writing some of these functions by accident!
also added doxy comments.
* ED_view3d_win_to_3d (was window_to_3d)
* ED_view3d_win_to_delta (was window_to_3d_delta)
* ED_view3d_win_to_vector (was window_to_3d_vector / viewvector)
* ED_view3d_win_to_segment_clip (was viewline)
* ED_view3d_win_to_ray (was viewray)
- follow rotate/pan/zoom/dolly operators.
- auto-depth preference works.
- smooth view navigation supported.
- view selected, all & numpad operator work too.
TODO
- deal with camera transform locked axis
- find a way to move/zoom the frame while the camera is locked (if it turns out to be a problem).
mouse coords would with cont. grab would wrap at short.
use mouse coords as int rather then short.
this problem still happens on linux because of XTranslateCoordinates
When in quad split view, operators that only apply to the unlocked region can now be accessed from menus and when the mouse is over a locked view.
Applied to:
- VIEW3D_OT_object_as_camera
- VIEW3D_OT_view_persportho
- VIEW3D_OT_view_orbit
- VIEW3D_OT_viewnumpad
- added notes to release todo's.
- renamed view3d view transform matching functions.
- added assert in edge split modifier to make a certain bug easier to spot.
- allow RegionView3D.view_matrix to be set.
- RegionView3D.view_rotation was inverted.
- add C function view3d_settings_from_mat()
note, intentionally removed NULL checks, double checked this is ok with callers.
most local modifier,GPU,ImBuf and Interface functions are now static.
also fixed an error were the fluid modifier definition and the header didnt have the same number of args.
3D View:
In quad-view mode, the options to set back/bottom/left views were
blocked. Now they work again.
Note: the oparator polls don't have a check for properties... so it
cannot be finegrained here. Checks are inside code.
Sketching Sessions.
Fix for secondary issue noted in this bug report. Some of the code for
the fancy 3d view sketching options needed to be moved around so that
there is a clearer "paint/sketch session" and "stroke" separation
between various stages. There's still some more stuff that needs to be
done here before I think it's totally cleaned up.
also minor functional changes
- OBJECT_OT_make_links_data() type property is now assigned to the operator property (so popup menu can find it)
- removing BG image now returns cancelled if no image is removed.
