	This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl` files. It defines a clear interface to evaluate the closure nodes leaving more flexibility to the render engine. Some of the long standing workaround are fixed: - bump mapping support is no longer duplicating a lot of node and is instead compiled into a function call. - bump rewiring to Normal socket is no longer needed as we now use a global `g_data.N` for that. Closure sampling with upstread weight eval is now supported if the engine needs it. This also makes all the material GLSL sources use `GPUSource` for better debugging experience. The `GPUFunction` parsing now happens in `GPUSource` creation. The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type agnostic. Is has also been rewritten in C++. This patch changes a view behavior for EEVEE: - Mix shader node factor imput is now clamped. - Tangent Vector displacement behavior is now matching cycles. - The chosen BSDF used for SSR might change. - Hair shading may have very small changes on very large hairs when using hair polygon stripes. - ShaderToRGB node will remove any SSR and SSS form a shader. - SSS radius input now is no longer a scaling factor but defines an average radius. The SSS kernel "shape" (radii) are still defined by the socket default values. Appart from the listed changes no other regressions are expected.

	Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

2020-11-03	Materials: add custom object properties as uniform attributes.	Alexander Gavrilov
	This patch allows the user to type a property name into the Attribute node, which will then output the value of the property for each individual object, allowing to e.g. customize shaders by object without duplicating the shader. In order to make supporting this easier for Eevee, it is necessary to explicitly choose whether the attribute is varying or uniform via a dropdown option of the Attribute node. The dropdown also allows choosing whether instancing should be taken into account. The Cycles design treats all attributes as one common namespace, so the Blender interface converts the enum to a name prefix that can't be entered using keyboard. In Eevee, the attributes are provided to the shader via a UBO indexed with resource_id, similar to the existing Object Info data. Unlike it, however, it is necessary to maintain a separate buffer for every requested combination of attributes. This is done using a hash table with the attribute set as the key, as it is expected that technically different but similar materials may use the same set of attributes. In addition, in order to minimize wasted memory, a sparse UBO pool is implemented, so that chunks that don't contain any data don't have to be allocated. The back-end Cycles code is already refactored and committed by Brecht. Differential Revision: https://developer.blender.org/D2057
2020-09-08	GPU: Cleanup implementation casts	Clément Foucault
	- Use the syntactic wrap/unwrap method to make code more readable. - Update comment about hidden struct behind opaque types. - Cleanup GPUDrawList type.

	No functional changes
2020-08-21	Cleanup: GPU: Update classes comments	Clément Foucault
	This should avoid confusion about what is a class and what is an opaque pointer.
2020-08-21	GPUUniformBuf: GL backend isolation	Clément Foucault
	This is in preparation of vulkan backend. We move all opengl functionnalities behind an abstract class. This also cleansup the "dynamic" ubo create and rename it to `GPU_uniformbuf_from_list()` Contains, no functional change. Part of T68990 Vulkan support.
2020-08-21	GPUUniformBuf: Rename struct and change API a bit	Clément Foucault
	This follows the GPU module naming of other buffers. We pass name to distinguish each GPUUniformBuf in debug mode. Also remove DRW_uniform_buffer interface.
