2012-09-04	Revert "Use one context per OSL thread. Not sure if this actually works, but ↵	Lukas Toenne
	the simple renderer example in OSL does it this way." This does not actually work: The context must not be shared between threads, but using the same context between different samples actually seems to prevent OSL from switching between shaders. The proper solution would be to ensure memory pooling works correctly. This reverts commit 69f87e69258d6266dcb20f09f7e3d4021e663432.
2012-09-04	OSL:	Thomas Dinges
	* Holdout shader is now working in OSL.
2012-09-04	Fix for OSL input parameter name mapping. When assigning input constants to ↵	Lukas Toenne
	shader parameters, use the compatible_name function to strip whitespace.
2012-09-04	Minor syntax error in musgrave osl texture.	Lukas Toenne

2012-09-04	OSL:	Thomas Dinges
	* WIP commit of fixes for musgrave and wave.
2012-09-04	Cycles: merge of changes from tomato branch.	Brecht Van Lommel
	Regular rendering now works tiled, and supports save buffers to save memory during render and cache render results. Brick texture node by Thomas. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures#Brick_Texture Image texture Blended Box Mapping. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures#Image_Texture http://mango.blender.org/production/blended_box/ Various bug fixes by Sergey and Campbell. * Fix for reading freed memory in some node setups. * Fix incorrect memory read when synchronizing mesh motion. * Fix crash appearing when direct light usage is different on different layers. * Fix for vector pass gives wrong result in some circumstances. * Fix for wrong resolution used for rendering Render Layer node. * Option to cancel rendering when doing initial synchronization. * No more texture limit when using CPU render. * Many fixes for new tiled rendering.
2012-09-04	OSL:	Thomas Dinges
	* Gradient texture renders now.
2012-09-04	Use one context per OSL thread. Not sure if this actually works, but the ↵	Lukas Toenne
	simple renderer example in OSL does it this way.
2012-09-04	Fix for bad memory leak in OSL: the context created for each OSL sample did ↵	Lukas Toenne
	not get released properly.
2012-09-04	fix for building without python, also rework python-main-loop control in the ↵	Campbell Barton
	BGE to not use RNA (use lower level BKE/BLI funcs instead)
2012-09-04	code cleanup: move file string defines into BLI_path_utils.h, ↵	Campbell Barton
	BKE_utildefines is now unused but keep incase we want to add defines there later.
2012-09-03	Fix for Cycles OSL: The RenderServices pointer in ShadingSystem is no longer ↵	Lukas Toenne
	accessible from the interface class (presumably because it is just the base class pointer anyway and would have to be casted). The OSLRenderServices pointer to our own implementation is now stored alongside the ShadingSystem in the kernel globals, so it can be accessed in thread_init.
2012-09-03	The shader id generated by the manager contains some special flags in high ↵	Lukas Toenne
	bits, leading to out-of-range index if used directly. This must use the SHADER_MASK to get actual array index.
2012-09-03	Fix #32089: non-progressive integrator issue with semi-transparent surfaces.	Brecht Van Lommel

2012-09-03	Fix #32046: GHOST_DropTargetWin32 memory leak, patch by Matt D.	Brecht Van Lommel

2012-09-03	Fix #32088: cycles crash removing a lamp with non-progressive sampling.	Brecht Van Lommel

2012-09-03	OSL / Cmake:	Thomas Dinges
	* Holdout shader was missing in cmake.
2012-09-03	Fix #32097: cycles window texture coordinate wrong, happened after 2.63.	Brecht Van Lommel

2012-09-03	Enable compilation of the SVM backend for Cycles even when OSL is enabled. ↵	Lukas Toenne
	The switch between SVM/OSL is decided at runtime, so the SVM code cannot simply be ignored when OSL is enabled. Currently all shader functions check the OSL/SVM flag to dispatch to the appropriate backend. If this turns out to be a significant overhead (unlikely) this test should be moved out of the inner loop.
2012-09-03	Fix #32144: cycles viewport missing update with dupliverts. Ideally this ↵	Brecht Van Lommel
	would be fixed in the dependency graph so it gives a proper signal but that would need a bigger refactor.
2012-09-03	* Added back UI switch for the Cycles shading system. Only visible when the ↵	Thomas Dinges
	feature set is "Experimental".
2012-09-03	Fix for OSL shader install paths.	Lukas Toenne

2012-09-03	RTTI needs to be disabled in cycles for OSL.	Lukas Toenne

2012-09-03	Added library linking for cycles_kernel_osl to OSL libraries and added ↵	Lukas Toenne
	cycles_kernel_osl to the list of blender libs in creator.
2012-09-03	Replaced dynamic_casts for node type checks by simple 'special type' ↵	Lukas Toenne
	identifiers. RTTI has to be disabled in cycles for OSL.
2012-09-02	Cycles compile fix: only use std::isfinite when OSL is enabled.	Lukas Toenne

2012-09-02	* Removed last occurrence of get_pointcloud_attr_query.	Thomas Dinges

2012-09-02	* OSL can't overwrite input parameters, use a local variable instead.	Thomas Dinges

2012-09-02	Cycles / OSL:	Thomas Dinges
	* Updates for noise_turbulence, to match svm function.
2012-09-02	Fixed a number of OSL syntax errors from the updated 1.2 API. Microfacet ↵	Lukas Toenne
	functions now all take an eta parameter, set to 1.0 if no IOR is given.
2012-09-02	Fix for r50314:	Thomas Dinges
	* oren_nayar is not part of the default stdosl, added it back.
2012-09-02	Fixed remaining syntax errors in OSL files. node_sepcomb_rgb.osl is split ↵	Lukas Toenne
	into 2 parts, since OSL only allows one shader per file.
2012-09-02	Cycles / OSL:	Thomas Dinges
	* Add oslutil.h, from osl 1.2.
2012-09-02	OSL / Cycles:	Thomas Dinges
	* Update the stdosl header file, from official osl 1.2.
2012-09-02	Cycles / OSL:	Thomas Dinges
	* Remove declaration of node_blend_weight_texture from cmake, does not exist, and match node_blend_weight name in nodes.cpp with the actual file.
2012-09-02	Cycles / OSL:	Thomas Dinges
	* First batch of compile fixes for several shaders, mainly syntax errors.
2012-09-02	Cycles / OSL:	Thomas Dinges
	Fixes for API changes in OSL RendererServices: * Added two new required get_matrix methods, from OSL RendererServices (otherwise the constructor fails). The two new matrix methods probably still need an implementation. * Removed deprecated "get_pointcloud_attr_query" and "pointcloud". There are two new routines for pointclouds, function headers for those are there. * Removed the (unused) PARTIO code parts from OSL. It was marked as not tested / not working, and due to the api changes here broken for sure. Code is still in svn history if needed.
2012-09-01	Cycles / OSL:	Thomas Dinges
	* Compile fix for the "direction_to_panorama" issue. Added kernel_projection.h to kernel_triangle.h.
2012-09-01	Fix #32463, Cycles crashing. The particle system sync_recalc part was ↵	Lukas Toenne
	checking object data, which can be NULL and doesn't actually say anything about particles, removed.
2012-09-01	Cycles fix: don't skip particle device update when there are no particle ↵	Lukas Toenne
	systems. The device texture always contains at least one dummy particle in case particle info node is used for non-instance objects, this must be initialized in any case.
2012-09-01	Cycles / OSLGlobals:	Thomas Dinges
	* Fixes for changes in the Open Shading Langauge API from version 0.6.0: https://github.com/imageworks/OpenShadingLanguage/commit/11ce51418b45e975ace4d919a4bdd8c2001ba300 * Removed the need for ShadingSystemImpl.
2012-09-01	Cycles / OSL:	Thomas Dinges
	* OSL namespace fixes for osl_shader.cpp.
2012-08-31	Cycles / OSL:	Thomas Dinges
	* Fixes for changes in r40163. Removed unused code and fixed emissive_eval function.
2012-08-31	Cycles: Fix for particle info node crash: The particle 'alive' state can be ↵	Lukas Toenne
	set to 'dying', which is just an indicator that the particle will be removed, but it is is used for instancing. This would lead to insufficient texture size and assert crash.
2012-08-31	Cycles: Fully initialize the dummy particle at index 0.	Lukas Toenne

2012-08-31	Cycles: Start the particle index for object instances at 1 instead 0. The ↵	Lukas Toenne
	first particle in the device texture is a dummy for non-instance objects using the particle info node.
2012-08-31	Cycles: Tag particle systems after syncing to make sure the particle system ↵	Lukas Toenne
	manager updates the device data.
2012-08-31	Added a bunch of additional particle state attributes to the Cycles particle ↵	Lukas Toenne
	info node: * Location: Basically the same as the location from Object Info node for object instances on particles, but in principle there could be additional offsets for dupli objects, so included for completeness. * Size: Single float scale of the particle. Also directly translates to object scale for current dupli objects, but handy to have as a single float to start with instead of a scale vector (currently not even exposed in Object Info). * Rotation: This is a quaternion, which are not yet supported by Cycles nodes. The float4 is copied to internal Cycles data and stored in the particles texture data, but the node doesn't have a socket for it yet and the data is not yet written to the stack. Code is just commented out so could be enabled quickly if/when rotation support is added to cycles. * Velocity: Linear velocity vector of particles. * Angular Velocity: Angular velocity around principle axes. The texture data is currently packed tightly into the particles texture, which saves a few bytes, but requires an additional texture lookup for some vector attributes which spread over two float4s. Could also add another float4 to particle size to avoid this.
2012-08-31	Fix for #32184 and redesign of particle storage in Cycles.	Lukas Toenne
	The particle data used by the Particle Info node was stored in cycles as a list in each object. This is a problem when the particle emitter mesh is hidden: Objects in cycles are only intended as instances of renderable meshes, so when hiding the emitter mesh the particle data doesn't get stored either. Also the particle data can potentially be copied to multiple instances of the same object, which is a waste of texture space. The solution in this patch is to make a completely separate list of particle systems in the Cycles scene data. This way the particle data can be generated even when the emitter object itself is not visible.
2012-08-31	Cycles / OSL:	Thomas Dinges
	* Assume OSL libs in the libdir.
