Creating a pipeline cache objectA PCO can be used to create either a graphics (vkCreateGraphicsPipelines) or compute pipeline (vkCreateComputePipelines). Creating these pipelines with a PCO ensures the reusability of the pipeline objects. If the PCO does not contain a similar pipeline, then it creates a new one and adds it to its pool.
