clutter_shader_finalize() was calling clutter_shader_release() which in
turn notifies "compiled". GObject was complaining that we were trying to
_ref() an object that was in _finalize().

Then, let's split release in two, with an _internal() version that does
not notify "compiled" and use it from dispose (as the object is still
usable after a call to release_internal().

The vertex attribute API assumes that if there is a color array
enabled then we can't determine if the colors are opaque so we have to
enable blending. The journal always uses a color array to avoid
switching color state between rectangles. Since the journal switched
to using vertex attributes this means we effectively always enable
blending from the journal. To fix this there is now a new flag for
_cogl_draw_vertex_attributes to specify that the color array is known
to only contain opaque colors which causes the draw function not to
copy the pipeline. If the pipeline has blending disabled then the
journal passes this flag.

There is an internal version of cogl_draw_vertex_attributes_array
which previously just bypassed the framebuffer flushing, journal
flushing and pipeline validation so that it could be used to draw the
journal. This patch generalises the function so that it takes a set of
flags to specify which parts to flush. The public version of the
function now just calls the internal version with the flags set to
0. The '_real' version of the function has now been merged into the
internal version of the function because it was only called in one
place. This simplifies the code somewhat. The common code which
flushed the various state has been moved to a separate function. The
indexed versions of the functions have had a similar treatment.

Cogl no longer has any code that assumes the buffer in a CoglBitmap is
allocated to the full size of height*rowstride. We should comment that
this is the case so that we remember to keep it that way. This is
important for cogl_texture_new_from_data because the application may
have created the data from a sub-region of a larger image and in that
case it's not safe to read the full rowstride of the last row when the
sub region contains the last row of the larger image.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2491
When uploading data for GLES we need to deal with cases where the
rowstride is too large to be described only by GL_UNPACK_ALIGNMENT
because there is no GL_UNPACK_ROW_LENGTH. Previously for the
sub-region uploading code it would always copy the bitmap and for the
code to upload the whole image it would copy the bitmap unless the
rowstride == bpp*width. Neither paths took into account that we don't
need to copy if the rowstride is just an alignment of bpp*width. This
moves the bitmap copying code to a separate function that is used by
both upload methods. It only copies the bitmap if the rowstride is not
just an alignment of bpp*width.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2491
The ffs function is defined in C99 so if we want to use it in Cogl we
need to provide a fallback for MSVC. This adds a configure check for
the function and then a fallback using a while loop if it is not
available.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2491
If we have to copy the bitmap to do the premultiplication then we were
previously using the rowstride of the source image as the rowstride
for the new image. This is wasteful if the source image is a subregion
of a larger image which would make it use a large rowstride. If we
have to copy the data anyway we might as well compact it to the
smallest rowstride. This also prevents the copy from reading past the
end of the last row of pixels.
An internal function called _cogl_bitmap_copy has been added to do the
copy. It creates a new bitmap with the smallest possible rowstride
rounded up the nearest multiple of 4 bytes. There may be other places
in Cogl that are currently assuming we can read height*rowstride of
the source buffer so they may want to take advantage of this function
too.

The builtin vertex attribute for the normals was incorrectly checked
for as 'cogl_normal' however it is defined as cogl_normal_in in the
shader boilerplate and for the name generated by CoglVertexBuffer.

Implement the ClutterStageWindow::set_accept_focus() virtual function in
the win32 backend.
If accept_focus is set to be TRUE then we call SetforegroundWindow()
after calling ShowWindow(). This is similar to what GDK does when
dealing with the same situation.

Allow the developer to set whether the Stage should receive key focus
when mapped. The implementation is fully backend-dependent. The default
value is TRUE because that's what we've been expecting so far.

If an actor is (unfortunately) queuing a relayout in relayout, you would
end up with (ClutterActor*)stage->needs_allocation set to TRUE and
stage->relayout_pending set to TRUE. But if then in the same cycle, an
actor calls clutter_actor_get_allocation_box, that will trigger another
(recursive) _clutter_stage_maybe_relayout, which will wrongly reset the
relayout pending to FALSE, while not actually performing a new relayout
because of the re-entrancy protection.

Keeping the Cogl 2.0 API reference in the build is getting far more
troublesome than it's worth.
It's breaking distcheck far too often, and it makes it impossible to
rebuild the build environment from tarballs - which is something that
some distributions (namely: the Debian-based ones, but not limited to
them) do in order to change build scripts using their own rules.
Added 3 examples for the box layout recipe:
1) Simple box layout demonstrating how to set actor properties
2) Trivial menu implementation using box layout
3) Demonstration app which enables tweaking and testing
of layout property interactions
Also inlined example 1 in the solution section and added
more explanatory text in the discussion.
Other frameworks expose the same functionality as "auto-reverse",
probably to match the cassette tape player. It actually makes sense
for Clutter to follow suit.
The test-viewport interactive test is exercising the clip code - a job
better done by the conformance test suite and by the test-clip
interactive test.
The test-project test case was an old test that was barely working after
landing the size allocation API in Clutter 0.8. It has never been fixed,
and it's been of relative use ever since.
The test-offscreen interactive test was a dummy test for the
ClutterStage:offscreen property, which has been deprecated and
not implemented since Clutter 1.0, and never really worked except
briefly in Clutter 0.2 or something.
The stage has a dirty flag to record whenever the viewport and
projection matrices need to be flushed. However after flushing these
the flags were never cleared so it would always redundantly update the
state.

The ARBfp fragend was bypassing generating a shader if the pipeline
contains a user program. However it shouldn't do this if the pipeline
only contains a vertex shader. This was breaking
test-cogl-just-vertex-shader.
Adding an action should allow passing a user data pointer, and have a
notification action that gets called when removing the action. This
allows introspection and language bindings to attach custom data to the
action - for instance, the real callable object that should be invoked.
