The builtin effects ClutterColorizeEffect, ClutterDesaturateEffect and
ClutterShaderEffect all have properties which only affect the
rendering of the final texture not the contents of it. When these
properties are updated we should queue a repaint of the effect not
the actor so that we don't waste time repainting the contents of the
offscreen buffer.

This adds a check for the EGL_KHR_surfaceless_opengl extension which we
depend on for being able to MakeCurrent (NO_SURFACE) as well as create a
context without and EGLConfig.

Since _cogl_winsys_kms_display_setup was basically just calling
setup_kms() it made sense to fold the code of setup_kms() back into the
_cogl_winsys_kms_display_setup() function.

To start with this backend only supports creating a single CoglOnscreen
framebuffer and will automatically set is up to display fullscreen on
the first suitable crtc it can find.
To compile this backend - get some dribbly black candles, sacrifice a
goat and configure with: --enable-kms-egl-platform
Note: There is currently a problem with using GLES2 with this winsys
so you need to run with EGL_DRIVER=gl
Note: If you have problems with mesa crashing in XCB during
eglInitialize then you may need to explicitly run with EGL_PLATFORM=gbm

There was an #ifdef'd section of code for profiling that was using the
wrong variable name so it would not build.

Previously the offscreen effect was keeping track of the size of the
texture so that it could detect when a different size is requested and
create a new texture. However this breaks if a subclass overrides
create_texture to make the texture bigger because in that case the
size of the texture will always be different from the calculated size
of the actor. This patch makes it also track the size of the fbo that
was requested before being passed through create_texture() and it
instead uses that to detect when a new FBO is needed.

It should be possible to define markers in ClutterScript when
describing a ClutterTimeline.
The syntax is a trivial:
"markers" : [
{ "name", <marker-name>, "time" : <msecs> }
]
While at it, we should document it inside the API reference, as well
as fleshing out the ClutterTimeline description.
When building with MSVC, symbols to be exported that point to data
need to be marked with dllimport to be successfully imported. The
_cogl_debug_flags variable is currently exported because it is used
from cogl-pango. This patch adds a COGL_EXPORT macro to cogl-util.h
which is used in cogl-debug.h

These are the VS 2008/2010 project files to build Cogl, with a README.txt
to explain the process involved.
Note that the Cogl and Cogl-Pango projects (and filters for VS2010) are
expanded with the correct source file listings during "make dist", which
is done to simplify maintenance of these project files.
-added preconfigured config.h(.win32.in), which is expanded with the
correct versioining info during autogen
-added preconfigued cogl/cogl-defines.h.win32
-added symbols files for cogl and cogl-pango
-Have configure.ac expand the config.h.win32.in into config.h.win32
with the correct versioning info, etc, and to include the Visual C++
project files for distribution
-Added rules in cogl/Makefile.am to expand the cogl VS 2008/2010 projects
and filters from the templates with up-to-date source file listings, to
distribute cogl-enum-types.c, cogl-enum-types.h to ease compilation and
to avoid depending on PERL on Windows installations.
-Added rules in cogl-pango/Makefile.am to expand the cogl-pango VS2008/
2010 projects and filters from the templates with up-to-date source file
listings.
-Added/edited various Makefile.am's in build to distribute the VS2008/2010
project files and associated items required for the build.
-Update .gitignore. There needs to be a pre-configured
config.h(.win32) and its template, config.h.win32.in for Visual C++
builds

To allow language bindings to properly override Script.connect_signals()
they'll need access access to Script.connect_signals_full().
Thanks to Jeremy Moles for reporting.
When comparing uniform values, it was not correctly handling the case
where pipeline0 has the value set but pipeline1 does not (only the
other way around) so it would crash.

When the flags contain a value that only has the most-significant bit
set then ffsl will return the size of an unsigned long. According to
the C spec it is undefined what happens when shifting by a number
greater than or equal to the size of the left operand. On Intel (and
probably others) this seems to end up being a no-op so the iteration
breaks. To fix this we can split the shift into two separate
shifts. We always need to shift by at least one bit so we can put this
one bit shift into a separate operator.

Rather than defining keybindings in static arrays generated at compile
time, store them in a hash table initialized in meta_display_init_keys()
and filled in init_builtin_keybindings().
This is a prerequisite for allowing to add/remove keybindings at runtime.

Since we have a _clutter_debug_message() function compiled in
unconditionally we have no further need for the equivalent conditional
version defined in clutter-profile.[ch]: we can simply do the work in
one function.
The change from CoglVertexBuffer to CoglPrimitive led to a change of the
default wrap-mode for the pipeline. Since using REPEAT can introduce
artifacts when sampling outside the [ 0, 1 ] texture coordinates range,
and since the default wrap mode was not documented anyway, we want to
keep the change from REPEAT to CLAMP, but it's worth adding an entry in
the release notes.
