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
and to Your Contributions.

1. Definitions.

   "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.
