TileBranch
* Cycles layers
* OpenEXR support

Merge trunk rev 45664-45710

Tile: Alpha Convert node (premul/key)

TileBranch
* The distortion node could read from unassigned memory. This is solved by this commit

TileBranch
* Added absolute scale and scene scale options

TileBranch
* added cycles passes

TileBranch
* fill an uninitialized value

TileBranch
* added caching operations to Distortion node.

With thanks to Sergey!

TileBranch
* added initial version of the MovieDistortion/MovieDistortion node.

TileBranch
* do not use area of interest, when the blur has already been calculated. Saves some time in the memory manager.

TileBranch
* fixed the vectorBlur additional artifacts. These were created as the editor output socket is an vector, but the output operation was a color. this color type was set to the editor node output socket type. this was an early optimization, and this is the only 'issue' that we can have with it :)
* replaced spaces => tabs in ConvertVectorToColor

TileBranch
* added quality setting for vector blur. The quality setting will change the actual number of samples to be calculated. With high quality the user selected number of samples will be used. with low this amount is divided by 3, medium by 2. Tests are needed if this suits in a normal workflow.

TileBranch
* added first implementation of the VectorBlur; It uses Blender Internal renderer to calculate the vectorBlur.
* still needs some work (artifacts + quality setting)

- At Mind -

TileBranch
* increased editing performance of the bilateral blur

- At Mind -

TileBranch:
* added a simple implementation of the bilateral blur. The implementation needs still has a lot of places to improve speed. The simplicity of the kernel makes it an ideal candidate for OpenCL!

TileBranch
* Added sampler operation to the Rotate node
* Added sampler operation to the Transform node

Effect:
* Bilinear, Bicubic, nearest filtering should work on MovieClips

TileBranch
* Fixed issue with Stabilize2d node.
reason of crash:
- the resolution of the movie clip attribute operation was set to the default values
- the system did a translate operation to center this
- these new added operations crashed the system

Tile branch
* added debug info (dot graph) during debugging;
* fixed issue in the movieclip node, where wrong connections where created

TileBranch
* Added a sampler node

With the sampler node it is possible to change image sample methods where you want.
Sampler only works for Images & MovieClips
