Since the Cogl 1.18 branch is actively maintained in parallel with the
master branch; this is a counter part to commit 1b83ef938fc16b which
re-licensed the master branch to use the MIT license.
This re-licensing is a follow up to the proposal that was sent to the
Cogl mailing list:
http://lists.freedesktop.org/archives/cogl/2013-December/001465.html
Note: there was a copyright assignment policy in place for Clutter (and
therefore Cogl which was part of Clutter at the time) until the 11th of
June 2010 and so we only checked the details after that point (commit
0bbf50f905)
For each file, authors were identified via this Git command:
$ git blame -p -C -C -C20 -M -M10 0bbf50f905..HEAD
We received blanket approvals for re-licensing all Red Hat and Collabora
contributions which reduced how many people needed to be contacted
individually:
- http://lists.freedesktop.org/archives/cogl/2013-December/001470.html
- http://lists.freedesktop.org/archives/cogl/2014-January/001536.html
Individual approval requests were sent to all the other identified authors
who all confirmed the re-license on the Cogl mailinglist:
http://lists.freedesktop.org/archives/cogl/2014-January
As well as updating the copyright header in all sources files, the
COPYING file has been updated to reflect the license change and also
document the other licenses used in Cogl such as the SGI Free Software
License B, version 2.0 and the 3-clause BSD license.
This patch was not simply cherry-picked from master; but the same
methodology was used to check the source files.

|
|
* @short_description: Interface for low-level textures like
|
|
* #CoglTexture2D and #CoglTexture3D.
|
|
*
|
|
* A #CoglPrimitiveTexture is a texture that is directly represented
|
|
* by a single texture on the GPU. For example these could be a
|
|
* #CoglTexture2D, #CoglTexture3D or #CoglTextureRectangle. This is
|
|
* opposed to high level meta textures which may be composed of
|
|
* multiple primitive textures or a sub-region of another texture such
|
|
* as #CoglAtlasTexture and #CoglTexture2DSliced.
|
|
*
|
|
* A texture that implements this interface can be directly used with
|
|
* the low level cogl_primitive_draw() API. Other types of textures
|
|
* need to be first resolved to primitive textures using the
|
|
* #CoglMetaTexture interface.
|
|
*
|
|
* <note>Most developers won't need to use this interface directly but
|
|
* still it is worth understanding the distinction between high-level
|
|
* and primitive textures because you may find other references in the
|
|
* documentation that detail limitations of using
|
|
* primitive textures.</note>
