There is a new internal Cogl function called _cogl_check_driver_valid
which looks at the value of the GL_VERSION string to determine whether
the driver is supported. Clutter now calls this after the stage is
realized. If it fails then the stage is marked as unrealized and a
warning is shown.
_cogl_features_init now also checks the version number before getting
the function pointers for glBlendFuncSeparate and
glBlendEquationSeparate. It is not safe to just check for the presence
of the functions because some drivers may define the function without
fully implementing the spec.
The GLES version of _cogl_check_driver_valid just always returns TRUE
because there are no version requirements yet.
Eventually the function could also check for mandatory extensions if
there were any.

We can not process events for a stage that has been destroyed so we
should make sure that the events for the stage are removed from the
global event queue during dispose.

Both ClutterAlpha:mode and ClutterAnimation:mode can be defined using:
• an integer id
• the "nick" field of the AnimationMode GEnumValue
• a custom, tweener-like string
All these methods should be documented.
Like in ClutterAlpha, ClutterAnimation:mode must be overridden when
parsing a Script definition, as we accept both a numeric id and the
string id for easing modes.
When _cogl_add_path_to_stencil_buffer is used to draw a path we don't
need to clear the entire stencil buffer. Instead it can clear just the
bounding box of the path. This adds an extra parameter called
'need_clear' which is only set if the stencil buffer is being used for
clipping.

With the change from bug 582639, we no longer call the reload
functions for properties that are not initially set, so the
initialization of fields in window.c has to match what
window-props.c would set for a missing property.
There was only one discrepancy, window->input, which needs
to be set to TRUE by default (or a window missing a WM_HINTS
property won't get focus); we also add explicit initializers
for a couple of fields that were getting 0-initialized
to the correct default value of FALSE for consistency with
the explicit intialization of the rest of the fields.

Since the rectangles packed inside the BoxLayout interactive test
have random colors it's not easy to verify the ordering. By using
the CoglPango API to print out the index in the middle of each
rectangle.
When the text direction changes we should evict the cached layouts
to avoid stale entries in case the direction change produces a layout
with the same size.
Every actor should have a property for retrieving (and setting) the
text direction.
The text direction is used to provide a consisten behaviour in both
left-to-right and right-to-left languages. For instance, ClutterText
should perform key navigation following text direction. Layout
managers should also take into account text direction to derive the
right packing order for their children.
Instead of using PangoDirection directly we should use the
ClutterTextDirection enumeration.
We also need a pair of accessor functions for setting and
getting the default text direction.
These changes caused the test to try to load redhand.png but this no
longer works since the TESTS_DATADIR changes in 0b4899ef23. The only
use of the hand is commented out anyway so it looks like the changes
were intended for temporary debugging.
With this, if one changes the underlying template files, we run
glib-mkenums again to generate updated glib_enum_[ch] files.

This fixes a warning about an uninitialised value. It could also
potentially fix some crashes for example if the enable_flags value
happened to include a bit for enabling a vertex array if no vertex
buffer pointer was set.

While loading a JPEG from disk (with clutter_texture_new_from_file),
I got the following:
<Error>: CGBitmapContextCreate: unsupported parameter combination: 8
integer bits/component; 24 bits/pixel; 3-component colorspace;
kCGImageAlphaNone; 3072 bytes/row.
<Error>: CGContextDrawImage: invalid context
Looking around, I found that CGBitmapContextCreate can't make 24bpp
offscreen pixmaps without an alpha channel...
This fixes the bug, and seems to not break other things...

Apple where nice and changed API between releases. This patch checks the
version of the compilation environment and tries to use the right parameter
type.
