Description

This extension is based on the VK_EXT_depth_clamp_zero_one extension. This extension gives defined behavior to fragment depth values which end up outside the conventional [0, 1] range. It can be used to ensure portability in edge cases of features like depthBias. The particular behavior is chosen to match OpenGL to aid porting or emulation.
