sets texture samplers in a compute program * Sets texture samplers in a compute program, if the samplers exist. Use this function to change the settings of texture samplers. * To set actual textures that should be bound to the samplers, use the `compute.set_textures` function instead. * * @name compute.set_samplers * * @param path [type:hash|string] The path to the re
