d024238fb2 Cycles / OpenCL: 
* Enable __KERNEL_SHADING__ per default for OpenCL.
This enables basic shading (color, emission, textures...) for AMD cards. 

You need the latest AMD catalyst driver in order to have this work.

6e93e33294 Cycles: add rejection of inf/nan samples, in principle these should not happen 
but this makes it more reliable for now.

Also add an integrator "Clamp" option, to clamp very light samples to a maximum
value. This will reduce accuracy but may help reducing noise and speed up
convergence.

e12adeb8c9 Fix #30551: cycles passes combining did not always give identical result combined 
with antialiasing/defocus, now divide out color at the very end instead of for each
sample.

755f018324 Cycles: shadow pass support. Note that this only takes into account lamps, 
emitting objects or world lighting do not contribute to the shadow pass.

Consider this more as a pass useful for some compositing tricks, unlike
other lighting passes this pass can't be used to exactly reconstruct the
combined pass.

33740c5eb5 Cycles: viewport rendered draw mode now shows background images, also changed the

d3c596035b Cycles / CUDA: 
* Make Cycles aware of Computing Capability 3.0, used by the new Kepler Cards.
You'll need the CUDA 4.2 Toolkit to compile it.

9b8dae71a5 Cycles: support for environment texture "Mirror Ball" projection mode, next to 
existing "Equirectangular". This projection is useful to create light probes
from a chrome ball placed in a real scene. It expects as input a photograph of
the chrome ball, cropped so the ball just fits inside the image boundaries.

Example setup with panorama camera and mixing two (poor quality) photographs
from different viewpoints to avoid stretching and hide the photographer:

9fba458a7f Cycles: float texture support. Due to GPU limitations there are now 95 byte, 
and 5 float image textures. For CPU render this limit will be lifted later
on with image cache support. Patch by Mike Farnsworth.

Also changed color space option in image/environment texture node, to show
options Color and Non-Color Data, instead of sRGB and Linear, this is more
descriptive, and it was not really correct to equate Non-Color Data with
Linear.

92322b57d4 Fix for 30439, Cycles node group conversion wasn't checking node->id pointer (group node without internal node tree). This is a somewhat unusual case (UI buttons don't allow unlinking group tree), but not entirely forbidden. 
Also fixed similar issue in node_templates.c where the group tree is used to generate a button name.

4a90339519 Cycles: support for camera rendering an environment map with equirectangular 
environment map, by enabling the Panorama option in the camera.

http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Camera#Panorama

The focal length or sensor settings are not used, the UI can be tweaked still to
communicate this, also panorama should probably become a proper camera type like
perspective or ortho.

3eaa46e80d Cycles: improve the Oren-Nayar BSDF (roughness value for Diffuse), to avoid 
undesired dark rings, and give more accurate lighting when the light is
behind the object. As a bonus, the code is simpler & faster.

b6d12f11fe Fix #30004: cycles brightness/contrast node issues. The formula used did not work 
very well for colors that can be outside of the 0.0..1.0 range, giving +/- infinity
results.

Now we just use a simple linear contrast factor as proposed by Paolo Sourvinos, and
clamp values to be >= 0, and also make the parameters work more in the 0..1 range
instead of the 0..100 range, to be more consistent with other nodes.
