Original change's description:
> Support large kernels on GPU in matrix convolution effect
>
> Currently matrix convolution falls back to CPU execution for large kernels, due to the argument limit for fragment shaders.
>
> Now for large kernels, we store them in a texture and sample them in a shader to sidestep the limit.
