When shading rate image usage is enabled in the bound pipeline, the pipeline uses a shading rate image specified by the command:
// Provided by VK_NV_shading_rate_image
commandBufferis the command buffer into which the command will be recorded.
imageViewis an image view handle specifying the shading rate image.
imageViewmay be set to VK_NULL_HANDLE, which is equivalent to specifying a view of an image filled with zero values.
imageLayoutis the layout that the image subresources accessible from
imageViewwill be in when the shading rate image is accessed.
