Blender Git Loki

Removed an unconventional typename use that causes problems with MSVC.

Refactor: renamed 'Expression' to 'Function'.

Removed unused deprecated code parts.

Disabled some unused function args.

Merge branch 'master' into object_nodes

Add support for texture node trees in new dependency graph.

Added clouds noise pattern node.

Use the material blending function for the RGB mix node for the time being.

Added the RGB mix node (unfinished).

Fix for debug output to avoid backward links when inputs/outputs share a name.

Added some more opcodes for scalar multiplication and division.

Added optional automatic datatype conversion for nodes.

This only applies to a handful of common types that can be unambiguously converted.
In any other case the link is considered invalid (proper error handling still needed).

Made node name arguments optional.

Node names are only used for identifying them in debugging, but
can just be autogenerated as well.

Make the compose/decompose and scalar math nodes work for textures.

Missing C header for the vfprintf function.

Merge branch 'master' into object_nodes

Added explicit vector input socket to the procedural texture nodes.

Added graphviz debug output for parsed bvm node graphs.

Cleanup for the texture node compiler API functions.

Removed unused code.
