- converting nurbs to mesh was casting the material to unsigned char.
- subsurf was casting to char, then int -> short in a loop.
- have material functions take & return shorts.
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.

==================
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.

- 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.
Removed the drawSelectedVerts and added drawSelectedVertices, which uses dm->foreachMappedVert.
In calc_weightpaint_vert_color():
Made the weight paint color black and return instead of input=-1
Made the pose bone selection normal when multi-paint is inactive.
Name fix for functions using mv instead of mvert.
Used vector functions provided by the math lib.
Changed some MEM_callocN references to be stacks.
Changed dm_deform_clear to use ob->derivedDeform primarily
Made the variable "float **changes" into "float (*changes)[2]"
Used CTX_data_active_object() in place of CTX_data_pointer_get_type()
Added the invert selection hotkey "Ctrl+I" to weight paint's vertex mask.
- use 'const float *' and array size in some function declarations.
- replace macros for BLI_math functions INPF, VECCOPY, VECADD etc.
- remove unused VertRen.clip struct member.
- remove static squared_dist() from 2 files, replace with BLI_math function len_squared_v3v3().
- use vertex arrays for drawing clipping background in the 3D viewport.
Use quite easy and stupid approach like it used for shape keys:
re-make editmesh (editcurve or editlattice) before creating index array
for hook or storing vertex index in parenting object.
Even if hook was added in "current" edit mode, it should be re-mapped on
loading edit data because topology could be changed after it was created.
Such kind of re-loading edit structures is the easiest way for now to
update keyindexes to relevant state.
Also, fixed bug with not re-mapping indices for vertex-parented objects.
Really old error, not sure why it wasn't noticed yet.
Change OURPLATFORM from "linux<major_version>" to simple "linux".
Since new policy for linux kernel versions that major version in
platform doesn't make much sense for building rules so the same
rules could be used for both of linux2 and linux3 now/
Tested on both of linux2 and linux3 systems.
Removed the extra, unused object mode specific selection functions I had added
(they aren't being used anywhere as of now, and they didn't support zbuffering).
Weight Paint Vertex Select tweaked to act like edit mode's select and Circle select was added, but clipping is not working properly for either.
Select all was added too, but to the Q key until I look into overriding A's select all bones.
The select vertices checkbox was moved to the header, but it does not force face select mask to turn off yet--and it doesn't have the correct icon.
There will definitely be an update tomorrow to fix the problems with all or most of the issues.
(No conflicts had to be manually resolved)
Gave weight paint a basic ability to draw edges and vertices with an option
(with colors for selected/unselected),
but I didn't make any vertex selection functions available in weight paint mode yet
(tested with edit mode for now).
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
