This re-licenses Cogl 1.18 under the MIT license 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.

Add _primitive_draw to replace _framebuffer_draw_primitive When splitting out the CoglPath api we saw that we would be left with inconsistent drawing apis if the drawing apis in core Cogl were lumped into the cogl_framebuffer_ api considering other Cogl sub-libraries or that others will want to create higher level drawing apis outside of Cogl but can't use the same namespace. So that we can aim for a more consistent style this adds a cogl_primitive_draw() api, comparable to cogl_path_fill() or cogl_pango_show_layout() that's intended to replace cogl_framebuffer_draw_primitive() Note: the attribute and rectangle drawing apis are still in the cogl_framebuffer_ namespace and this might potentially change but in these cases there is no single object representing the thing being drawn so it seems a more reasonable they they live in the framebuffer namespace for now. Note: the cogl_framebuffer_draw_primitive() api isn't removed by this patch so it can more conveniently be cherry picked to the 1.16 branch so we can mark it deprecated for a short while. Even though it's marked as experimental api we know that there are people using the api so we'd like to give them a chance to switch to the new api.
