Description

This extension adds a new structure, VkDepthBiasRepresentationInfoEXT, that can be added to a pNext chain of VkPipelineRasterizationStateCreateInfo and allows setting the scaling and representation of depth bias for a pipeline.

This state can also be set dynamically by using the new structure mentioned above in combination with the new vkCmdSetDepthBias2EXT command.
