## 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.
