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.
The GL framebuffer driver now makes sure to bind the framebuffer
before counting the number of bits. Previously it would just query the
number of bits for whatever framebuffer happened to be used last.
In addition the virtual for querying the framebuffer bits has been
modified to take a pointer to a structure instead of a separate
pointer to each component. This should make it slightly more efficient
and easier to maintain.

This moves the direct use of GL in cogl-framebuffer.c for handling
cogl_framebuffer_read_pixels_into_bitmap() into
driver/gl/cogl-framebuffer-gl.c and adds a
->framebuffer_read_pixels_into_bitmap vfunc to CoglDriverVtable.

This adds a new "nop" driver that does nothing. This can be selected at
runtime either with the COGL_DRIVER=nop environment variable or by
passing COGL_DRIVER_NOP to cogl_renderer_set_driver()
Adding the nop driver gives us a way to test workloads without any
driver and hardware overheads which can help us understand how Cogl's
state tracking performs in isolation.
Having a nop driver can also serve as an shell/outline for creating
other drivers later.
