The Khronos Intellectual Property Rights defines the terms 'Scope',
'Compliant Portion', and 'Necessary Patent Claims'.

Some parts of this Specification are purely informative and so are EXCLUDED from
the Scope of this Specification. The <<introduction-conventions>> section of the
<<introduction>> defines how these parts of the Specification are identified.

Where this Specification uses <<introduction-technical-terminology,technical

enabling technologies that are not expressly set forth in this
Specification, those enabling technologies are EXCLUDED from the Scope of
this Specification.
For clarity, enabling technologies not disclosed with particularity in this
Specification (e.g. semiconductor manufacturing technology, hardware
architecture, processor architecture or microarchitecture, memory
architecture, compiler technology, object oriented technology, basic
operating system technology, compression technology, algorithms, and so on)
are NOT to be considered expressly set forth; only those application program
interfaces and data structures disclosed with particularity are included in
the Scope of this Specification.

For purposes of the Khronos Intellectual Property Rights Policy as it relates
to the definition of Necessary Patent Claims, all recommended or optional
features, behaviors and functionality set forth in this Specification, if
implemented, are considered to be included as Compliant Portions.

Where this Specification includes <<introduction-normative-references,
normative references to external documents>>, only the specifically
identified sections of those external documents are INCLUDED in the Scope of
this Specification. If not created by Khronos, those external documents may
contain contributions from non-members of Khronos not covered by the Khronos

=== Description

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.

shaders replace depth values, for example), and this extension does not change
