Update the configure.ac to use the LT_INIT() instead of the deprecated
AC_PROG_LIBTOOL. This also allows us to depend on a specific libtool
version, namely one that doesn't thoroughly suck.
Some EGL drivers for embedded devices require a specific framebuffer
device to be opened and passed to eglCreateWindowSurface(). Since it's
optional, we can provide an environment variabled called
CLUTTER_FB_DEVICE that can be used to specify the path of the device
to be opened.

Update the EGL native framebuffer backend to be 1.2-ready:
» create the EGL context and the surface inside the create_context()
implementation so that a context is always available
» simplify the StageWindow implementation
» clean up old code

Just like _cogl_texture_2d_new_with_size(),
_cogl_texture_2d_new_from_bitmap() needs to check if an unsliced
texture can be created at the given size, or if hardware
limitations prevent this.

cogl_read_pixels() no longer asserts that the format passed in is
RGBA_8888 but instead accepts any format. The appropriate GL enums for
the format are passed to glReadPixels so OpenGL should be perform a
conversion if neccessary.
It currently assumes glReadPixels will always give us premultiplied
data. This will usually be correct because the result of the default
blending operations for Cogl ends up with premultiplied data in the
framebuffer. However it is possible for the framebuffer to be in
whatever format depending on what CoglMaterial is used to render to
it. Eventually we may want to add a way for an application to inform
Cogl that the framebuffer is not premultiplied in case it is being
used for some special purpose.
If the requested format is not premultiplied then Cogl will convert
it. The tests have been changed to read the data as premultiplied so
that they won't be affected by the conversion. Picking in Clutter has
been changed to use COGL_PIXEL_FORMAT_RGB_888 because it doesn't need
the alpha component. clutter_stage_read_pixels is left unchanged
because the application can't specify a format for that so it seems to
make most sense to store unpremultiplied values.

* stage-min-size-rework:
docs: Update minimum size accessors
actor: Use the TOPLEVEL flag instead of a type check
[stage] Use min-width/height props for min size
The clutter-profile.c print_report() code would crash if no stats had
been gathered because uprof would return NULL for the "Redrawing" timer
which we then dereferenced.
This changes the code to start by checking for the "Mainloop",
"Redrawing" and "Do Pick" timers and if none are present it returns
immediately without generating any report.
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.
Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.
As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

There is no need for us to check for low-level functions and header
files, especially since we haven't been checking the results until
now. This makes cross-compiling slightly more bearable.
If the actor is an internal child of another actor then we should call
unparent() when destroying it, like clutter_actor_reparent() does;
otherwise we'll leak the actor, since the parent holds a reference to
it.

Instead of shadowing these properties with different properties with the
same names on stage, actually use them. Behaviour should be identical,
except the minimum stage size can now be enforced by setting the
min-width/height properties as well as using the set_minimum_size
function.
Require automake >= 1.10, and add the following options:
» dist-bzip2: create a bz2 tarball in the dist process
» check-news: check that we changed the NEWS file prior to dist,
to avoid another release without NEWS updates, like 1.1.10
If we do not unset the Stage we will have stale data, and the Crossing
event when re-entering a Stage will not be emitted, as the actor under
the pointer might be the same as before.
This adds a COGL_INDICES_TYPE_UNSIGNED_INT enum value so that unsigned
ints can be used with cogl_vertex_buffer_indices_new. Unsigned ints
are not supported in core on GLES so a feature flag has also been
added to advertise this. GLES only sets the feature if the
GL_OES_element_index_uint extension is available. It is an error to
call indices_new() with unsigned ints unless the feature is
advertised.

Allow a ClutterModel to be constructed through the ClutterScript API.
Currently this allows a model to be generated like like this:
{
"id" : "test-model",
"type" : "ClutterListModel",
"columns" : [
[ "text-column", "gchararray" ],
[ "int-column", "gint" ],
[ "actor-column", "ClutterRectangle" ]
]
}
where 'columns' is an array containing arrays of column-name,
column-type pairs.

The code has gotten really complicated to follow.
As soon as we have a sync-to-vblank mechanism we should just bail out.
Also, __GL_SYNC_TO_VBLANK (which is used by nVidia) should be assumed
equivalent to a CLUTTER_VBLANK_GLX_SWAP.
We should explain what a "key frame" is for ClutterAnimator, possibly
with some sort of visual cue.
This allows me to demonstrate my poor skills at using Inkscape, as well
as my overall bad taste for graphics design.
The top-level types list was comically out of date, and it was only
determining whether the type we were constructing was initially unowned
or a full object. We can safely replace it with a simple type check.
It would be useful to be able to share the Timeline across different
animator instances, or with different animation constructs. Also this
allows sharing definitions of Timelines in ClutterScript.
The arguments for remove_key() can be NULL, but there is an extraneous
assertion that fails if they are. The pre-conditions should match the
documentation, in this case.
A sub-class of ClutterBox might add ChildMeta support, and since
pack_at() does not go through clutter_container_add_actor(), we
need to manually call the create_child_meta() ourselves.
It is conceivable that Container implementations might add children
outside of the Container::add() implementation - e.g. for packing at
a specific index. Since the addition (and removal) might happen outside
the common path we need to expose all the API that is implicitly called
by ClutterContainer when adding and removing a child - namely the
ChildMeta creation and destruction.
The adds tests for the remaining layer combine functions, the 1 minus
value operator and the TEXTURE_N source. Note however that Cogl
currently fails when parsing a TEXTURE_N source so the test is
commented out.
Previously the GLES2 backend needed a special wrapper for
glBindTexture because it needed to know the internal GL format of the
texture in order to correctly implement the GL_MODULATE texture env
mode. When GL_MODULATE is used then the RGB values are taken from the
previous texture layer rather than being fetched from the
texture. However since the material API was added Cogl no longer uses
the GL_MODULATE texture env mode but instead always uses GL_COMBINE.
Compiling the GLES2 backend broke since the more-texture-backends
branch merge because the cogl_get_internal_gl_format function was
removed and there was one place in GLES2 specific code that was using
this to bind the texture.
The texture layer combine functions are now hard coded to GL_COMBINE
instead of GL_MODULATE. The combine function can be customized with
all the parameters of GL_COMBINE. A shader is generated to implement
the given parameters.
Currently it will try to generate code for the constant color but it
will use a uniform which does not exist.
The GLES2 backend for Cogl is failing to compile because
GL_MAX_TEXTURE_UNITS is not defined. Let's define it and provide a
wrapper which uses GL_MAX_TEXTURE_IMAGE_UNITS or
COGL_GLES2_MAX_TEXTURE_UNITS, whichever is the smallest.
A bogus ClutterInterpolation argument had been carried from
clutter_animator_set_interpolation to clutter_animator_get_interpolation
in copy and paste.
GLib 2.24 (but starting from the 2.23.2 unstable release) added a new
macro for collecting GValues from a va_list.
The newly added G_VALUE_COLLECT_INIT() macro should be used in place
of initializing the GValue and calling G_VALUE_COLLECT(), and improves
the collection performances by avoiding multiple checks, free and
initialization calls.
