Implements a more flexible internal connect function for standard nodes
(compositor, shader, texture). Allow feasible datatype connections by
priority.
The priorities for common datatypes in compositor, shader and texture
nodes are encoded in a simple function. Certain impossible connections
(e.g. color -> cycles shader) are excluded by giving them -1 priority.
Priority overrides link status: If a higher priority input can be found,
this will be used regardless of link status. Link status only comes into
play for inputs with same priority.

It would include/exclude shadow depending on the pass being disabled/enabled,
but that should have no influence on the combined render result. Now it always
includes shadow.

Blender Internal shader nodes.
All nodes now use the `nodestack_get_vec` function to convert whatever
input values are connected to the desired type, instead of using the
stack values directly regardless of what they contain.
Note that this might break old node setups that have been adapted to the
faulty behavior, but as discussed in the bug report the 2.70 version is
the right time to fix this.

BI.
The shaderfrom setting in the node editor only makes sense for "new"
shading nodes (cycles), otherwise it should be ignored and default to
SNODE_SHADER_OBJECT.

don't get updated based on context.
As discussed in T38340 the solution is to use the current scene from
context whenever feasible.
Composite does not use node->id at all now, the scene which owns the
compositing node tree is retrieved from context instead.
Defocus node->id is made editable by the user. By default it is not set,
which also will make it use the contextual scene and camera info.
The node->id pointer in Defocus is **not** cleared in older blend files.
This is done for backward compatibility: the node will then behave as
before in untouched scenes.
File Output nodes also don't store scene in node->id. This is only needed
when creating a new node for initializing the file format.

The same can be achieved by flipping normals on the mesh, but it can be
convenient to do this in the shader.

Now it uses the last activated node like compositing does. This should have no
effect on existing files until you activate another output node there.

not really needed anyway, but need to be adjusted to make use of the
socket value copy methods.
|
|
The sanity check for copying socket default value was using the socket
idname for type compatibility checks, which is too strict. Subtypes
would not be recognized as copyable, but since only the plain data type
is needed below this is all that needs to be checked.
That alone would not cause crash (just missing default value copy),
but the tree view template was messing with the default_value DNA
directly by freeing it in advance, which is not necessary and should
be left to blenkernel when freeing the node. Otherwise this would
leave the node invalid without a default_value if the copy function
bails out.

* Henyey-Greenstein scattering closure implementation.
* Rename transparent to absorption node and isotropic to scatter node.
* Volume density is folded into the closure weights.
* OSL support for volume closures and nodes.
* This commit has no user visible changes, there is no volume render code yet.
This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.

moved the hide preview logic to a method on bNodeTreeType. This way the node.c keeps clean, but logic could still be shared.
Implementing this per node, can lead to future errors.

information such as light vector from specified Lamp.
For now this provides the following outputs:
- Color
- Light Vector
- Distance
- Shadow
- Visibility Factor
Note: Color output is multiplied by the lamp energy. Multiplication of
color*max(dot(light_vector,normal_vector),0)*shadow*visibility_factor
produces the exact same result as the Lambert shader.
Many thanks to Brecht for code review and discussion!

GLSL code for view vector output of "Geometry" node.
Revert 0c7d2de38219. The "Camera Data" node actually gives the location
of the point in camera coordinate system. To obtain actual camera data,
we can use "Geometry" node instead.
Also modify the "Geometry" node, to produce correct view vector output
in orthographic GLSL preview.

so that it becomes (1.0, 1.0, 1.0) when AO is disabled.
For materials using AO pass, this makes the material preview and the GLSL
preview more accurate, but shouldn't affect final rendering in most cases
because we usually enable AO when using the AO pass in node tree.

for either mode are converted into equivalent settings of the other. This keeps the result of both modes roughly the same and
mimics the previous behavior when settings were shared by both modes (but not equivalent).
NOTE: Due to the use of additional sRGB conversion in the LGG mode the result is not entirely accurate, this should perhaps be fixed.
Settings for each mode are kept in their own color values nevertheless, this avoids potential problems with float precision.

offset/power/slope variables for the CDL mode in color balance node. This avoids stupid default values in particular for offset, which would be 1 when just using the lift value for it.

shader node editor. The 'free' callback for node execution data was accessed from the node->typeinfo, but this pointer can
become invalid because the render database is not immediately freed after the job finishes. To avoid access to dangling node pointers, store the function callback in the exec data itself. The node
pointer must not be accessed in the free function (wasn't used before either), these functions are purely for the execution data.

Scene/Render "spaces" are actually absolute values, they do not use the input X/Y scale factors, hide them in this case.
Thanks to Lukas for review and improvement!

* Keep the Mapping node default type as Point for now, instead of Texture. The
latter is a better default, but this is breaking API compatibility and it's
too close to release to expect addons to be fixed in time.
* Vector Transform and Mapping nodes had properties with name "type" to set the
type of vector, but this conflicts with the node type property, so renamed to
vector_type now.

scale and rotation in mapping node, there would be shearing, and the only way
to avoid that was to add 2 mapping nodes. This is because to transform the
texture, the inverse transform needs to be done on the texture coordinate
Now the mapping node has Texture/Point/Vector/Normal types to transform the
vector for a particular purpose. Point is the existing behavior, Texture is
the new default that behaves more like you might expect.

A new hair bsdf node, with two closure options, is added. These closures allow the generation of the reflective and transmission components of hair. The node allows control of the highlight colour, roughness and angular shift.
Llimitations include:
-No glint or fresnel adjustments.
-The 'offset' is un-used when triangle primitives are used.

file/layer slots (input sockets) can be added without using the operator. Instead of adding sockets to these node using the
node.inputs collection, the node.file_slots or node.layer_slots collections should be used. Both of them work, they just provide slightly different properties for use with simple files or multi-layer
EXR.
The FileOutput node design is cumbersome and should be considered broken. It should eventually be replaced, the problem with that is backward/forward compatibility.
