This optimizes a few loops that become significant bottlenecks during viewport rendering of scenes with large numbers of curves. To render a curves object, Blender needs to generate a potentially very large (but trivial) index buffer. As previously implemented, this index buffer is generated in an extremely inefficient manner, with a single-threaded loop and an explicit function call per entry. The buffer then needs to be pushed onto the GPU, which is also a fairly slow task. The PR generates the index buffer directly on the GPU with compute shader.
