This patch implements the necessary changes to the GPU module that are needed by the realtime compositor. A new function GPU_material_from_callbacks was added to construct a GPU material from a number of callbacks. A callback to construct the material graph by adding and linking the necessary GPU material nodes. And the existing code generator callback. This essentially allows the construction of GPU materials independent of node trees and without the need to do any node tree localization. A new composite source output to the code generator was added. This output contains the serialization of nodes that are tagged with GPU_NODE_TAG_COMPOSITOR, which are the nodes linked to the newly added composite output links. Two new GPU uniform setters were added for int2 and matrix3 types. Shader create info now supports generated compute sources. Shaders starting with gpu_shader_compositor are now considered part of the shader library. Additionally, two fixes were implemented. First, GPU setter node de-duplication now appropriately increments the reference count of the references resources. Second, unlinked sockets now get their value from their associated GPU node stack instead of the socket itself. Differential Revision: https://developer.blender.org/D14690 Reviewed By: Clement
