This adds much more comprehensive support for gobject-introspection
based bindings by registering all objects as fundamental types that
inherit from CoglObject, and all structs as boxed types.

The DriverCallback is a function that is defined by the Windows SDK 8.0+
headers, which was initially used for device driver development. The use
of DriverCallback would cause a clash, causing things to break when built
with newer Windows SDKs, so rename DriverCallback to CoglDriverCallback to
avoid this problem.

In commit 1b83ef938f the license in the plugin description was changed
from “LGPL” to “MIT”. GStreamer strictly whitelists the names of the
licenses and the correct name for the MIT license is “MIT/X11” so it
was rejecting the plugin.

To help facilitate integration with third party frameworks this exposes
the EGL context and display to applications as well as the GLX context.
(Note that the GLX display is already available via
cogl_xlib_renderer_get_display())
This adds a new top-level <cogl/cogl-glx.h> header that needs to be
included explicitly to access the glx specific api.
Anyone using these apis will be responsible for checking that Cogl
is indeed using EGL or GLX by calling cogl_renderer_get_winsys_id()
This will enable GStreamer, for example, to be able to create a GL
context that shares resources with Cogl's context.

This splits out the GLeglImageOES define in cogl-egl.h into a private
cogl-egl-private.h header and updates the guards in cogl-egl.h to be
consistent with other top-level headers where we need to be careful
about how __COGL_H_INSIDE__ is defined and undefined, esp when the
gobject introspection scanner is running.

This ensures we use EGLNativeWindowType and EGLNativeDisplayType
everywhere instead. The previous names come from EGL 1.2 but it seems
reasonable to require more recent EGL versions. If someone wanted to add
compatibility for EGL 1.2 later it would be straightforward to define
the new names to the old.

Since we don't generate a mipmap chain for uploaded video frames this
avoids setting the min filter to COGL_PIPELINE_FILTER_LINEAR_MIPMAP_LINEAR.
Since COGL_PIPELINE_FILTER_LINEAR is the default and since it is also
dubious that cogl-basic-video-player is directly manipulating layers
that are conceptually internal to cogl-gst this removes the loop that
updates the filtering for cogl-gst layers.

This makes sure video textures being uploaded via
video_texture_new_from_data are allocated before the function returns.
This function create a CoglBitmap to wrap the data from gstreamer and by
allowing cogl to allocate the texture lazily it's possible that the data
being pointed to by the bitmap won't remain valid until we actually come
to allocate the texture.
Note: we don't simply use cogl_texture_2d_[sliced_]new_from_data() here
because we need to be able to call cogl_texture_set_premultiplied()
before allocating the texture.

We have an #ifdef EGL_WL_bind_wayland_display guard in

This winsys feature flag is exposed via the deprecated
cogl_clutter_winsys_has_feature function and Clutter is curently
relying on it. Previously the EGL winsys was only setting the internal
COGL_EGL_WINSYS_FEATURE_BUFFER_AGE flag and there was no mapping to
the public flag. Therefore the feature would only be used on GLX. This
patch just adds the mapping.

This adds a PlatformToolset tag in order to make upgrading the projects to
Visual Studio 2012/2013 formats easier, especially when done with a script.
The script, for example, can change the value inside these tags
apporpriately to do the upgrade job quite easily.
This updates the Visual Studio 2010 Projects in the following ways,
similar to the recent changes to the Visual Studio 2008 projects:
-Make all the copying of the pre-configured header files custom build
rules, so that it is cleaner when people clean their builds, and the files
can be re-copied when updated.
-Split up the property sheets, so to ease future maintenance
-Make the cogl-path library built as a DLL
-Build and link against SDL-2.x for SDL builds
-Make everything except the .sln file and the README.txt file use UNIX line
endings, for easier maintenance.
-Merge cogl_sdl.sln and install-sdl.vcxproj into cogl.sln and
install.vcxproj respectively.
-Update build of the conformance test to not use COGL_COMPILATION, and make
it link to cogl-path.
Split up the property sheets, so that it is easier to maintain, and update
the project files accordingly. Also clean up the project files by
finishing up the merge of the *_sdl.vcproj items into their regular
counterparts, and dropping all the *_sdl.* files.
Make use of UNIX line endings for all the MSVC 2008 build files, except the
.sln file and the README.txt files, for easier maintenance.
We need to link the conformance test executable to cogl-path, so make that
project depend on the cogl-path project, so that it will link to it as
well.
...for all of the copying of the pre-configured headers for Cogl. This
makes it much easier for people using the projects for building Cogl to
clean up files that are "generated", and this commit is the last bit for
it. Also clean up the property sheets as a result.
Also fix the Cogl project that it does indeed look for headers in
cogl/deprecated, so that the build is fixed.
Similar updates to the Visual Studio 2010 Projects will follow.
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.
Not doing so leads to the following error, if stddef.h is not included
indirectly through EGL headers:

The _cogl_egl_texture_2d_new_from_image function has a CoglError
argument which implies that it is unlike the other texture
constructors and returns errors immediately rather than having a
delayed-allocation mechanism. cogl_wayland_texture_2d_new_from_buffer
which calls it is also like this. We can't rely on delayed-allocation
semantics for this without changing the applications because the
texture needs to be allocated before the corresponding EGLImage is
destroyed. This patch just makes it immediately allocate.
A better patch might be to remove the error argument to make it
obvious that there are delayed-allocation semantics and then fix all
of the applications.
This was breaking Cogland and Mutter.

The previous implementation was dereferencing the sample pointer in
order to get the offset to subtract from the member pointer. The
resulting value is then only used to get a pointer to the member in
order to calculate the offset so it doesn't actually read from the
memory location and shouldn't cause any problems. However this is
probably technically invalid and could have undefined behaviour. It
looks like clang takes advantage of this undefined behaviour and
doesn't actually offset the pointer. It also generates a warning when
it does this.
This patch splits the _cogl_container_of macro into two
implementations. Previously the macro was always used in the list
iterator macros like this:
SomeType *sample = _cogl_container_of(list_node, sample, link)
Instead of doing that there is now a new macro called
_cogl_list_set_iterator which explicitly assigns to the sample pointer
with an initial value before assigning to it again with the real
offset. This redundant initialisation gets optimised out by compiler.
The second macro is still called _cogl_container_of but instead of
taking a sample pointer it just directly takes the type name. That way
it can use the standard offsetof macro.

If no context is set on the CoglGstVideoSink then it would previously
call gst_caps_ref with a NULL pointer. This patch makes it just return
NULL instead. I think that is a valid thing to do because that is what
gst_base_sink_default_get_caps does. If we don't do this then it's not
possible to use CoglGstVideoSink with GstParse because that tries to
link the pipeline after parsing the string. That was previously
causing a critical error because the freshly parsed sink doesn't have
a CoglContext.
