+Khronos Open Source Contributor License Agreement
+
+In order to clarify the intellectual property license granted with
+Open Source Contributions from any person or entity to any products
+The Khronos Group (“Khronos”) manages or maintains and makes available
+under the www.apache.org/licenses/LICENSE-2.0 license, as indicated by
+a copyright notice that is included in or attached to the product (the
+"Work"), Khronos must have an Open Source Contributor License Grant
+("Grant") on file that has been signed by each Contributor, indicating
+agreement to the license terms below. This license is for your
+protection as a Contributor as well as the protection of Khronos; it
+does not change your rights to use your own Contributions for any
+other purpose.
+
+You accept and agree to the following terms and conditions for Your
+present and future Contributions submitted to Khronos. Except for the
+license granted herein to Khronos and recipients of software
+distributed by Khronos, You reserve all right, title, and interest in

-institute patent litigation against any entity (including a cross-claim or counterclaim 
-in a lawsuit) alleging that the Work or a Contribution incorporated within the Work 
-constitutes direct or contributory patent infringement, then any patent licenses granted 
-to You under this License for that Work shall terminate as of the date such litigation

-generated by the Derivative Works, if and wherever such third-party notices normally 
-appear. The contents of the NOTICE file are for informational purposes only and do not 
-modify the License. You may add Your own attribution notices within Derivative Works 
-that You distribute, alongside or as an addendum to the NOTICE text from the Work,

-the conditions stated in this License.

-(including negligence), contract, or otherwise, unless required by applicable law (such 
-as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor 
-be liable to You for damages, including any direct, indirect, special, incidental, or 
-consequential damages of any character arising as a result of this License or out of the 
-use or inability to use the Work (including but not limited to damages for loss of 
-goodwill, work stoppage, computer failure or malfunction, or any and all other 
-commercial damages or losses), even if such Contributor has been advised of the 
-possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing the Work or 
-Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of 
-support, warranty, indemnity, or other liability obligations and/or rights consistent 
-with this License. However, in accepting such obligations, You may act only on Your own 
-behalf and on Your sole responsibility, not on behalf of any other Contributor, and only 
-if You agree to indemnify, defend, and hold each Contributor harmless for any liability 
-incurred by, or claims asserted against, such Contributor by reason of your accepting 
-any such warranty or additional liability.

-
+   "You" (or "Your") shall mean the copyright owner or legal entity
+   authorized by the copyright owner that is making this Grant. For
+   legal entities, the entity making a Contribution and all other
+   entities that directly or indirectly control, are controlled by, or
+   are under common control with that entity are considered to be a
+   single Contributor. For the purposes of this definition, "control"
+   means (i) the power, direct or indirect, to cause the direction or
+   management of such entity, whether by contract or otherwise, or
+   (ii) ownership of fifty percent (50%) or more of the outstanding
+   shares, or (iii) beneficial ownership of such entity.
+
+   "Contribution" shall mean any original work of authorship,
+   including any modifications or additions to an existing work, that
+   is intentionally submitted by You to Khronos for inclusion in, or
+   documentation of, the Work. For the purposes of this definition,
+   "submitted" means any form of electronic, verbal, or written
+   communication sent to Khronos or its representatives, including but
+   not limited to communication on electronic mailing lists, source
+   code control systems, and issue tracking systems that are managed
+   by, or on behalf of, Khronos for the purpose of discussing and
+   improving the Work, but excluding communication that is
+   conspicuously marked or otherwise designated in writing by You as
+   "Not a Contribution."
+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   this Grant, You hereby grant to Khronos and to recipients of
+   software distributed by Khronos a perpetual, worldwide, non-
+   exclusive, no-charge, royalty-free, irrevocable copyright license
+   to reproduce, prepare derivative works of, publicly display,
+   publicly perform, sublicense, and distribute Your Contributions and
+   such derivative works. You acknowledge that Khronos is not
+   obligated to use Your Contribution as part of the Work and may
+   decide to include only Contributions that Khronos considers
+   appropriate.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+   this Grant, You hereby grant to Khronos and to recipients of
+   software distributed by Khronos a perpetual, worldwide, non-
+   exclusive, no-charge, royalty-free, irrevocable (except as stated
+   in this section) patent license to make, have made, use, offer to
+   sell, sell, import, and otherwise transfer the Work, where such
+   license applies only to those patent claims licensable by You that
+   are necessarily infringed by Your Contribution(s) alone or by
+   combination of Your Contribution(s) with the Work to which such
+   Contribution(s) was submitted. If any entity institutes patent
+   litigation against You or any other entity (including a cross-claim
+   or counterclaim in a lawsuit) alleging that your Contribution, or
+   the Work to which you have contributed, constitutes direct or
+   contributory patent infringement, then any patent licenses granted
+   to that entity under this Grant for that Contribution or Work shall
+   terminate as of the date such litigation is filed.
+
+4. Moral Rights. If moral rights apply to Your Contribution, to the
+   maximum extent permitted by law, You waive and agree not to assert
+   such moral rights against Khronos, our successors in interest, or
+   any of our licensees, either direct or indirect.
+
+5. You represent that you are legally entitled to grant the above
+   license. If your employer(s) has rights to intellectual property
+   that you create that includes your Contributions, you represent
+   that you have received permission to make Contributions on behalf
+   of that employer, that your employer has waived such rights for
+   your Contributions to Khronos, or that your employer has executed a
+   separate Corporate Contributor License Grant with Khronos.
+
+6. You represent that each of Your Contributions is Your original
+   creation (see section 8 for submissions on behalf of others). You
+   represent that Your Contribution submissions include complete
+   details of any third-party license or other restriction (including,
+   but not limited to, related patents and trademarks) of which you
+   are personally aware and which are associated with any part of Your
+   Contributions.
+
+7. You are not expected to provide support for Your Contributions,
+   except to the extent You desire to provide support. You may provide
+   support for free, for a fee, or not at all. Unless required by
+   applicable law or agreed to in writing, You provide Your
+   Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS
+   OF ANY KIND, either express or implied, including, without
+   limitation, any warranties or conditions of TITLE, NON-
+   INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
+
+8. Should You wish to submit work that is not Your original creation,
+   You may submit it to Khronos separately from any other
+   Contribution, identifying the complete details of its source and of
+   any license or other restriction (including, but not limited to,
+   related patents, trademarks, and license agreements) of which you
+   are personally aware, and conspicuously marking the work as
+   "Submitted on behalf of a third-party: [named here]".
+
+9. You agree to notify Khronos of any facts or circumstances of which
+   you become aware that would make these representations inaccurate
+   in any respect.
