This patch implements the Inpaint node for the Realtime Compositor. The inpainting region is filled by sampling the color of the nearest boundary pixel if it is not further than the user supplied distance. Additionally, a lateral blur is applied in the tangential path to the inpainting boundary to smooth out the inpainted region. The implementation is not identical to the existing CPU implementation due to technical infeasibility. In particular, the CPU implementation uses a Manhattan distance transform, while the GPU implementation uses an Euclidean one, which is a consequence of the use of the Jump Flooding algorithm. Furthermore, the CPU uses a serial convolution starting from the boundary outwards, while the GPU uses a lateral Gaussian blur in the direction tangent to the boundary.
