vkCmdSetFragmentShadingRateKHR

To dynamically set the pipeline fragment shading rate and combiner operation, call:

void vkCmdSetFragmentShadingRateKHR(
    VkCommandBuffer           commandBuffer,
    const VkExtent2D*                           pFragmentSize,
    const VkFragmentShadingRateCombinerOpKHR    combinerOps[2]);

• commandBuffer is the command buffer into which the command will be recorded.
• pFragmentSize specifies the pipeline fragment shading rate for subsequent drawing commands.
• combinerOps specifies a VkFragmentShadingRateCombinerOpKHR determining how the pipeline, primitive, and attachment shading rates are combined for fragments generated by subsequent drawing commands.

This command sets the pipeline fragment shading rate and combiner operation for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_FRAGMENT_SHADING_RATE_KHR set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineFragmentShadingRateStateCreateInfoKHR values used to create the currently active pipeline.
