2019-09-06	EEVEE: Fix bump mapping	Clément Foucault
	Fix issue in latest patch and assure derivatives calculation is correct on all GPU.
2019-09-06	Eevee: Use manual derivatives for better quality bump.	Clément Foucault
	We basically duplicate the height map branch plugged into the bump node, and tag each node in each branch as dx/dy/ref using `branch_tag`. Then we add a one pixel offset on the texture coordinates if the node is tagged as dx or dy. The dx/dy branches are plugged into (new) hidden sockets on the bump node. This match cycles bump better but have a performance impact. Also, complex nodetrees can now become instruction limited and not compile anymore.

2019-08-30	GPU: Split gpu_shader_material into multiple files.	OmarSquircleArt
	This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch. Reviewers: brecht Differential Revision: https://developer.blender.org/D5616
