It is supported for the GL_DEPTH24_STENCIL8_OES format

https://bugzilla.gnome.org/show_bug.cgi?id=666184

It allows creating a new EGL context, associating a framebuffer to it
and using raw GL to draw into it.

Re-apply the cogl-defines.h as appropriate if one chooses to change
his/her mind on whether he/she wants to build the SDL winsys.

Should read "Visual C++ 2010", not "Visual C++ 2008"-sorry for the
oversight.

Distribute the new VS2008/2010 project/solution files and the
pre-configured cogl-defines.h(.win32_SDL) needed for the build with MSVC.

This had to be in another commit as git am did not like a mixture of
file updates with Windows and Unix EOL.

Should deal with the conflicts that Neil talked about in his comments
for the bug :)

The Visual C++ .sln files must have Windows EOL-somehow GIT insisted that
they are added with UNIX EOL :|

This includes the SDL+COGL test program...

The corresponding README.txt's have been updated with corresponding info
for this support.

Create a pre-configured cogl-defines.h for use during Visual C++
compilation of the SDL winsys (this is in addition to the Win32/WGL
winsys).

The foreach_sub_texture_in_region implementation tries to forward the
function on to its child texture but it was mistakenly forwarding back
on to itself so it would just recurse endlessly and crash.

This will make autotools fill in the versioning info for the COGL/
COGL-Pango .rc files and distribute the resulting .rc files

Integrate the COGL/COGL-Pango .rc files into the build so that the built
DLLs reveal the versioning and copyright info

This tells people on the versioning info and copyright info of the
COGL/COGL-Pango DLLs.  The versioning values are inserted during the
autogen stage.

This adds a simple example based on the hello example but that forces
the SDL winsys and listens for mouse motion events to move the
triangle.

The SDL winsys was missing a few minor features, such as the
implementation. This patch adds that in.

CoglTexture2D had an assert to verify that the EGL winsys was being
used. This doesn't make any sense any more because the EGL winsys
can't be used directly but instead it is just a base winsys for the
platform winsys's. To fix this this patch adds a set of 'criteria'
flags to each winsys, one of which is 'uses EGL'. CoglTexture2D can
use this to determine if the winsys is supported.

Eventually we might want to expose these flags publically so that an
application can select a winsys based on certain conditions. For
example, an application may need a winsys that uses X or EGL but
doesn't care exactly which one it is.

If a frame callback is destroyed before it is invoked then the struct
would be freed but it would not be removed from the array of callbacks
so when cogland later tried to emit the callback it would crash. This
patch instead stores the callbacks in a GQueue with embedded list
nodes so that they can be removed from the list in the resource
destructor. That way it doesn't matter how the resource is destroyed,
it will still get removed from the list.

Wayland has changed so that the shell interface now only has one
function which returns a shell surface for the surface. This patch
makes it create a dummy service in the same way that the wayland demo
compositor does. The implementation of the shell_surface_interface for
that dummy service is all no-ops.

Tabs make me sad.

Eventually we might want to have an XCB-based EGL winsys. We already
have xlib-specific API in CoglRenderer (eg, to set a foreign display)
so the application needs to be able to specifically select between XCB
and XLIB.

This also removes the POWERVR part while renaming
COGL_HAS_EGL_PLATFORM_POWERVR_X11_SUPPORT to
COGL_HAS_EGL_PLATFORM_XLIB_SUPPORT because the winsys is equally
applicable to Mesa.

This moves all of the code specific to the Android platform out of
cogl-winsys-egl. It is completely untested apart from that it
compiles using a dummy android/native_window.h header.

The egl_surface_width/height properties in CoglDisplayEGL were
accidentally being conditionally defined depending on KMS
support. They are not necessary because CoglDisplayKMS also already
stores the width/height and this was just copied over to the EGL
dipslay.

It looks like the documentation for this option has a copy-and-paste
