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.
Previously the WGL winsys was expecting the application to send all
windows messages to Cogl via the cogl_win32_renderer_handle_event
function. When using a GLib main loop we can make this work
transparently to the application with a GSource for the magic
G_WIN32_MSG_HANDLE file descriptor. That causes the GMainLoop to wake
up whenever a message is available.
This patch makes the WGL winsys add that magic value as a source fd.
This will only have any meaning if the application is using glib, but
it shouldn't matter because the cogl_poll_renderer_get_info function
is documented to only work on Unix-based winsys's anyway.
This patch is an API break because by default Cogl will now start
stealing all of the Windows messages. Something like Clutter that wants to handle
its own event retrieval would now need to call
cogl_win32_renderer_set_event_retrieval_enabled to stop Cogl from
stealing the events.

This fixes some problems which were stopping --disable-glib from
working properly:
• A lot of the public headers were including glib.h. This shouldn't be
necessary because the API doesn't expose any glib types. Otherwise
any apps would require glib in order to get the header.
• The public headers were using G_BEGIN_DECLS. There is now a
replacement macro called COGL_BEGIN_DECLS which is defined in
cogl-types.h.
• A similar fix has been done for G_GNUC_NULL_TERMINATED and
G_GNUC_DEPRECATED.
• The CFLAGS were not including $(builddir)/deps/glib which was
preventing it finding the generated glibconfig.h when building out
of tree.

To delimit which symbols were considered experimental we used to use
some preprocessor defines to gives experimental symbols an _EXP suffix
so that anyone monitoring the ABI for changes would easily be able to
discount changes made to clearly experimental functions.
These days we simply rely on the gtk-doc "Stability: unstable"
annotation to serve this purpose because changing the actual symbol name
made it slightly more awkward to debug Cogl using GDB and was an extra
mechanical step we decided we could do without.
This patch removes the last remaining _EXP suffix defines in Cogl
(cherry picked from commit 5a1c4a979e00accd492097cfb8f6a8d0fd8331bc)
This adds a cogl-win32-renderer.h for the win32 specific cogl-renderer
API instead of having #ifdef guards in cogl-renderer.h
