193871ae7d Cycles: Ignore preprocessing time in ETA calculation
This patch makes Cycles ignore the time spent in BVH construction etc. when
estimating the remaining time. Considering that the remaining time is calculated
based on the average time per tile so far, as far as I understand it makes no
sense to include the preprocessing time.

ee36e75b85 Cleanup: Fix Cycles Apache header.
This was already mixed a bit, but the dot belongs there.

bd0b9ed0c0 Cycles: Add dedicated Progress::set_error() call
Currently it acts the same as set_cancel(), but this way we're able to
distinguish situations when rendering was aborted by user demand (for
example pressing Esc in standalone renderer) or if something went horribly
wrong (for example out of VRAM error).

fc55c41bba Cycles Bake: show progress bar during bake
Baking progress preview is not possible, in parts due to the way the API
was designed. But at least you get to see the progress bar while baking.

76525d5398 Cycles: persistent images option
This option enables keeping loaded images in the memory in-between
of rendering.

Implemented by keeping render engine alive for until Render structure
is being freed.

Cycles will free all data when render finishes, optionally keeping
image manager untouched. All shaders, meshes, objects will be
re-allocated next time rendering happens.

Cycles cession and scene will be re-created from scratch if render/
scene parameters were changed.

This will also allow to keep compiled OSL shaders in memory without
need to re-compile them again.

P.S. Performance panel could be cleaned up a bit, not so much happy
     with it's vertical alignment currently but not sure how to make
     it look better.

 P.P.S. Currently the only way to free images from the device is to
       disable Persistent Images option and start rendering.

adea12cb01 Cycles: merge of changes from tomato branch.
Regular rendering now works tiled, and supports save buffers to save memory
during render and cache render results.

Fix part of thread safety issue, there's still something else wrong.

66b1dfae89 Cycles: tweaks to properties and nodes
* Passes renamed to samples
* Camera lens radius renamed to aperature size/blades/rotation
* Glass and fresnel nodes input is now index of refraction
* Glossy and velvet fresnel socket removed
* Mix/add closure node renamed to mix/add shader node
* Blend weight node added for shader mixing weights

There is some version patching code for reading existing files, but it's not
perfect, so shaders may work a bit different.

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later.
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
