* Added per surface options "influence scale" and "radius scale" for tweaking brush settings individually for each surface.
* Added option to completely disable drying. This should be nice for indefinitely spreading paint etc.
* Improved paint mixing algorithm.
* "Paint effects" now work in relative mesh space instead of global. This means that effect speed remains same for identical shapes regardless of their size.
* Complete rewrite of "spread effect" algorithm. It now works much better in all test cases done. Old algo sometimes produced artifacts and stopped spreading too early.
* Adjustments / rewrite on some parts of dripping algorithm to make it work better with transparent paint.
* Added a new "color dry" setting. It can be used to define wetness level when paint colors start to shift to surface "background". Lower values can be useful to prevent spreading paint from becoming transparent as it dries, while higher (default) values give better results in general.
* Fix: If multiple displace/wave surfaces were used simultaneously, displace was applied using wrong normal.
Please note that due to these changes in "paint effects" system older save files may require some tweaking to match results from previous versions.
File subversion is bumped to two in order to copy over the old fields.
This removes two RNA properties, sculpt_paint_use_unified_size and
sculpt_paint_use_unified_strength.

Instead of generally hiding all unused sockets in collapsed mode, the sockets now have a new explicit flag SOCK_AUTO_HIDDEN, which is only toggled when the hide_toggle operator is called. This way the auto-hidden sockets stay as they are when nodes are duplicated etc. The new flag is necessary to distinguish between manually hidden sockets (via hide_sockets_toggle operator) and automatically hidden sockets and restore the node state when unhiding a node.
- Rotation now happens around initial stroke location rather than around scene origin
- Added slider for rotation strength which helps in cases only few rotation is needed
to be to increase the precision of such strokes
- use NULL rather then 0 for pointers
- use static functions where possible
- add own includes to ensure func's and their declarations don't get out of sync.
Warning!
Angles in nodes have just been moved to consistant Radians values (ANGLE subtype of RNA Float property). You will still see them as degrees in the GUI, though, unless you chose otherwise in Scene properties, Units panel.
Conversion from degrees to radians for old files is obviously done at loading time, but if you use a mixed pipeline of trunk and releases, be carefull!
Loading a 2.60.4 file (or higher) into any previous version of Blender, your angles in nodes will have odd values (well, radians interpreted as degrees)!
And if you save such file in a pre-2.60.4 version, the angle node values will be converted again when loaded in Blender 2.60.4 or higher...
This affects following nodes:
* Compo: Rotate, Defocus, ChromaMatte, Glare and DirectionalBlur
* Shader: Mapping
And all future code using the TexMapping struct’s rotation part (its rot memember is now in radians).
ColorMapping struct for color manipulation of textures. These will be the
standard built-in texture node options for manipulating the incoming texture
coordinate and outgoing color.
Separate DNA properties for bounding box used for bounding box display
in 3d viewport and bounding box used for collision detection in game engine.
Bumped subversion for proper updating old files to new system, but it
need more complex testing.
Files created in blender before this revision should be rendered in
exactly the same way they used to render before.
Patch by Morten Mikkelsen, finished by Ton and me.
Summary:
========
The idea here is to move the texface options into the material panel.
For images with the change please visit:
http://code.blender.org/index.php/2011/09/bge-material-texface-changes
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.

This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too.
