ab2c273b12 Added GPL header to sconscripts! 
Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

a0855a95db Cycles: add "Textures" panel in particle properties, to make it possble to add 
textures when Cycles is selected as render engine.

176292067e Cycles OSL: small optimization to geometry node, tangent output still was 
not properly optimized out in some cases.

For reference, setting this will give detailed information about OSL shaders:
export OSL_OPTIONS="statistics:level=1,debug=1,llvm_debug=1"

06888b7beb Cycles OSL minor optimizations: recycle shading context, don't do memory 
allocations for trace data, avoid some virtual function calls. Only helps
a few percentages.

error in some builds.

5616c7a058 Cycles: disable scaling up of ray differentials after diffuse/glossy bounce, this 
isn't working well for OSL texture filtering and wasn't very helpful to begin
with, a better solution should be possible.

3945979f2b Fix #33486: cycles CPU image textures were offset wrong by half a pixel compared 
to OpenGL/CUDA/OSL rendering.

3759c10e5c Fix #33485: cycles OSL now autodetects the presence of emission and transparent 
closures to enable multiple importance sampling and transparent shadows.

188718a3d5 OSL Shader Files: 
* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.

43c04eefe3 Cycles: RGB and Vector Curves nodes now supported, with the limitation that the 
range must be left to the default (0..1 and -1..1).

7c81952179 Cycles: trick to make building with OSL trunk work as well, it has a different 
name for LoadMemoryShader so we make it call the right name depending on which
is available.

369b9fcf0f Fix missing mapping and influence panel for particles when cycles is selected 
as render engine. Still missing is colors and texture slots, but that's too
tricky to fix this close to release.

38dcce2da2 FIX: OSL mix shader clamps 2nd color component to 3rd one. 
Previously the OSL Mix shader node was clamping the 2nd color component (green) to the 3rd color component (blue). Now every component is clamped on its own.

a9d889cba4 Fix #33405: preview render getting stuck in a particular .blend file, ObjectKey 
operator< had wrong brackets, changed it now to be more clear.

Fix #33404: crash GPU rendering with OSL option still enabled. There was a check
to disable OSL in this case, but it shouldn't have modified scene->params because
this is used for comparison in scene->modified().

41f98978e3 Fix cycles issue when NaN is used for RGB ramp, can access array out of bounds then. 
OSL noise() function is generating NaN's in certain cases, fix for that goes to our
OSL branch.

Also add missing minimum weight and max closure checks to OSL, forgot to add these
when fixing another bug.

7c0a0bae79 Fix #33375: OSL geom:trianglevertices gave wrong coordinates for static BVH. 
Also some simple OSL optimization, passing thread data pointer directly instead
of via thread local storage, and creating ustrings for attribute lookup.

186bdbd8d8 Fix #33344: cycles motion blur was still crashing on CUDA sm 2.0. Solution now 
is also an optimization, use quaternion nlerp instead of slerp, there's no good
reason to use slerp, and nlerp is faster too.

0d6976ad0c Fix #32900: object motion blur not working on the GPU. To make this work I disabled motion 
blurring of scale animation, probably not a big loss in practice since it's not so common
to animate this, can be added back later.

ceed3ef640 Fix #32907: failure rendering a complex node setup, hitting fixed max number 
of closures limit. Optimized the code now so it can handle more.

Change SVM mix/add closure handling, now we transform the node graph so that
the mix weights are fed into the closure nodes directly.
