An application might for whatever reason want to control a specific output
directly and have cogl only swap the other outputs if any. So add an api that

The surfaceless context extension can be used to bind a context
without a surface. We can use this to avoid creating a dummy surface
when the CoglContext is first created. Otherwise we have to have the
dummy surface so that we can bind it before the first onscreen is
created.
The main awkward part of this patch is that theoretically according to
the GL and GLES spec if you first bind a context without a surface
then the default state for glDrawBuffers is GL_NONE instead of
GL_BACK. In practice Mesa doesn't seem to do this but we need to be
robust against a GL implementation that does. Therefore we track when
the CoglContext is first used with a CoglOnscreen and force the
glDrawBuffers state to be GL_BACK.
There is a further awkward part in that GLES2 doesn't actually have a
glDrawBuffers state but GLES3 does. GLES3 also defaults to GL_NONE in
this case so if GLES3 is available then we have to be sure to set the
state to GL_BACK. As far as I can tell that actually makes GLES3
incompatible with GLES2 because in theory if the application is not
aware of GLES3 then it should be able to assume the draw buffer is
always GL_BACK.

Currently, due to the way that Visual Studio 2010+ projects are handled,
the "install" project does not re-build upon changes to the sources, as it
does not believe that its dependencies have changed, although the changed
sources are automatically recompiled. This means that if a part or more
of the solution does not build, or if the sources need some other fixes
or enhancements, the up-to-date build is not copied automatically, which
can be misleading.
Improve on the situation by forcing the "install" project to trigger its
rebuild, so that the updated binaries can be copied. This does trigger an
MSBuild warning, but having that warning is way better than not having an
up-to-date build, especially during testing and development.
When a new CoglAtlasTexture tries to fit into an existing CoglAtlas
it should make sure the atlas stays valid while it expands.

This environment variable predates the reliable platform detection in mesa

it also leaks into the GNOME session, preventing clients from

Cogl, when built with the SDL winsys, includes the SDL headers in its
headers, which causes main() to be defined to SDL's main() wrapper on
Windows, which means that SDL2.lib and SDL2main.lib need to be linked to
every single program that links to Cogl with the SDL winsys.
Avoid this behavior by defining SDL_MAIN_HANDLED in the CFLAGS of the
sample and test programs, and let people know that this is the case.
Remove #pragma directives that causes any applications that use Cogl to
link to the SDL libraries when Cogl was built with the SDL winsys. This is
mainly due to the availability of both SDL-1.x and SDL-2.x support in the
SDL winsys, where different libraries are linked for SDL-1.x and SDL-2.x.
To avoid having to link to the SDL/SDL2 libraries when the application code
is not directly using SDL/SDL2, define SDL_MAIN_HANDLED in the CFLAGS so
that SDL's wrapper main() implementation will not be used when the
application is being built.

cogl_gst_video_sink_get_natural_size was using g_return_val_if_fail

The pkg-config file might not necessarily be installed yet so I don't
think it makes sense to try and include it when running g-ir-scanner.
Presumably it should pick up the headers from source directory instead
of the installed directory. It seems to build without this patch so
let's just revert it.
This reverts commit d9c8570f14.
