5da0064de7 constraint: Add ::update_allocation()
The Constraint should plug directly into the allocation mechanism, and
modify the allocation of the actor to which they are applied to. This is
similar to the mechanism used by the Effect class to modify the paint
sequence of an actor.

d1b4495f7f offscreen-effect: Update handling of transforms
In line with the changes made in f5f066df9c to clean up how Clutter
deals with transformations of actors this patch updates the code in
clutter-offscreen-effect.c. We now query the projection matrix from the
stage instead of the perspective and instead of duplicating the logic to
setup the stage view transform we now use
_clutter_actor_apply_modelview_transform for the stage instead.

f0ab8edac0 clutter.modules: Specify the checkoutdir for the gtk2 module
If no checkoutdir is specified then jhbuild seems to use the name of
the module which in this case would be 'gtk+'. This ends up
overwriting the checkout of the master branch of gtk+ and causes all
kinds of build problems. This patch adds a checkoutdir attribute to
the gtk2 module to force it to checkout into the gtk2 directory.

7338541452 cogl: Make cogl_util_next_p2 internal and fix the documentation
cogl_util_next_p2 is declared in cogl-util.h which is a private header
so it shouldn't be possible for an application to use it. It's
probably not a function we'd like to export from Cogl so it seems
better to keep it private. This patch renames it to _cogl_util_next_p2
so that it won't be exported from the shared library.

The documentation for the function is also slightly wrong because it
stated that the function returned the next power greater than
'a'. However the code would actually return 'a' if it's already a
power of two. I think the actual behaviour is more useful so this
patch changes the documentation rather than the code.

42dacf97f8 cogl-vertex-buffer: Don't always set COGL_MATERIAL_FLUSH_FALLBACK_MASK
Previously CoglVertexBuffer would always set the flush options flags
to at least contain COGL_MATERIAL_FLUSH_FALLBACK_MASK. The code then
later checks whether any flags are set before deciding whether to copy
the material to implement the overrides. This means that it would
always end up copying the material even if there are no fallback
layers. This patch changes it so that it only sets
COGL_MATERIAL_FLUSH_FALLBACK_MASK if fallback_layers != 0.

8cfb158f63 material-arbfp: fix updating params if sharing progs
If a single arbfp program is being shared between multiple CoglMaterials
then we need to make sure we update all program.local params when
switching between materials. Previously we had a dirty flag to track
when combine_constant params were changed but didn't take in to account
that different materials sharing the same program may have different
combine constants.

d87522596d material-arbfp: Another pass at simplifying the code
Previously the backend private state was used to either link to an
authority material or provide authoritative program state. The mechanism
seemed overly complex and felt very fragile. I made a recent comment
which added a lot of documentation to make it easier to understand but
still it didn't feel very elegant.

This patch takes a slightly different approach; we now have a
ref-counted ArbfpProgramState object which encapsulates a single ARBfp
program and the backend private state now just has a single member which
is a pointer to one of these arbfp_program_state objects. We no longer
need to cache pointers to our arbfp-authority and so we can get rid of
a lot of awkward code that ensured these pointers were
updated/invalidated at the right times. The program state objects are
not tightly bound to a material so it will also allow us to later
implement a cache mechanism that lets us share state outside a materials
ancestry. This may help to optimize code not following the
recommendations of deriving materials from templates, avoiding one-shot
materials and not repeatedly modifying materials because even if a
material's ancestry doesn't naturally lead us to shareable state we can
fallback to searching for shareable state using central hash tables.

f6dc3ddcba material: Adds experimental cogl_material_foreach_layer API
This adds a way to iterate the layer indices of the given material since
cogl_material_get_layers has been deprecated. The user provides a
callback to be called once for each layer.

Because modification of layers in the callback may potentially
invalidate any number of the internal CoglMaterialLayer structures and
invalidate the material's layer cache this should be more robust than
cogl_material_get_layers() which used to return a const GList *
pointing directly to internal state.

5583d9c12e material-arbfp: don't recompile for constant changes
Instead of lazily incorporating combine constants as arbfp PARAM
constants in the source directly we now use program.local parameters
instead so we can avoid repeating codegen if a material's combine
constant is updated. This should be a big win for applications animating
a constant used for example in an animated interpolation, such as
gnome-shell.

2815cf4719 material-arbfp: don't redo codegen for texture changes
This makes it so we don't consider LAYER_STATE_TEXTURE changes to affect
the arbfp code. This should avoid a lot of unneeded passes of
code generation for applications modifying the texture for a layer.

3adeef6604 material: make layer/material_pre_changes mutually exclusive
This makes it so we only notify backends of either a single material
change or a single layer change. Previously all material STATE_LAYERS
changes would be followed by a more detailed layer change.

For backends that perform code generation for fragment processing they
typically need to understand the details of how layers get changed to
determine if they need to repeat codegen. It doesn't help them to report
a material STATE_LAYERS change for all layer changes since it's so
broad, they really need to wait for the layer change to be notified.

What does help though is to report a STATE_LAYERS change for a change in
material->n_layers because they typically do need to repeat codegen in
that case.

a114843f74 material: pass material owner for layer pre changes
When notifying a backend about a layer being modified we now pass the
layers current owner for reference. NB: Although a layer can indirectly
be referenced by multiple layers, a layer is considered immutable once
it has dependants, so there is only ever one material associated with a
layer being modified. Passing the material pointer to the backends
layer_pre_change callback can be useful for backends that associate
their private state with materials and may need to update that state in
response to layer changes.

d9a32f979c arbfp: rename get_arbfp_authority clarifying semantics
This renames the get_arbfp_authority function to
get_arbfp_authority_no_check to clarify that the function doesn't
validate that the authority cache is still valid by looking at the age
of the referenced material. The function should only be used when we
*know* the cache has already been checked.

ed1123a06b material: track if material change is layer change
We now pass a boolean to _cogl_material_pre_change_notify to know when
a material change is as a result of a layer change. We plan to use this
information to avoid notifying the backends about material changes if
they are as a result of layer changes. This will simplify the handling
of state changes in the backends because they can assume that layer and
material changes are mutually exclusive.

53acf4d1b0 material: Adds _get_layer_combine_constant API
This adds an internal _cogl_material_get_layer_combine_constant function
so we can query the current layer combine constant back. We should

this so we can read the constant in the arbfp backend.

thing that has been moved into this is the sampled boolean to know when
a particular texture unit gets sampled from in the generated arbfp code.

98516061c3 Enumeration value should be on the same line
The glib-mkenums script is not clever enough to deal with

  FLAGS_VALUE = FLAGS_A |
                FLAGS_B

And since this breaks the enumeration GType and the introspection data,
we cannot really wait for it to be fixed.

fb7bf9ce02 profile: Update to uprof-0.3 dep for --enable-profile
When building with --enable-profile we now depend on the uprof-0.3
developer release which brings a few improvements:

» It lets us "fix" how we initialize uprof so that instead of using a shared
object constructor/destructor (which was a hack used when first adding
uprof support to Clutter) we can now initialize as part of clutter's
normal initialization code. As a side note though, I found that the way
Clutter initializes has some quite serious problems whenever it
involves GOptionGroups. It is not able to guarantee the initialization
of dependencies like uprof and Cogl. For this reason we still use the
contructor/destructor approach to initialize uprof in Cogl.

» uprof-0.3 provides a better API for adding custom columns when reporting
timer and counter statistics which lets us remove quite a lot of manual
report generation code in clutter-profile.c.

» uprof-0.3 provides a shared context for tracking mainloop timer
statistics. This means any mainloop based library following the same
"Mainloop" timer naming convention can use the shared context and no
matter who ends up owning the final mainloop the statistics will always
be in the same place. This allows profiling of Clutter with an
external mainloop such as with the Mutter compositor.

» uprof-0.3 can export statistics over dbus and comes with an ncurses
based ui to vizualize timer and counter stats live.

The latest version of uprof can be cloned from:

a45f67bbdc cogl-framebuffer: Clear the renderbuffer list on failure
When try_creating_fbo fails it deletes any intermediate render buffers
that were created. However it doesn't clear the list so I think if it
failed a second time it would try to delete the render buffers
again. This could potentially cause problems if a subsequent fbo is
created because the destructor for the original might delete the
renderbuffers of the new fbo.

570fa3f044 clone: scale src with apply_transform not cogl_scale
Since a ClutterClone may be allocated a different size than its source
actor we need to apply a scale factor before painting the source actor.
We were manually using cogl_scale to do this in clutter_clone_paint but
really this kind of thing is best handled in an implementation of the
apply_transform virtual so Clutter can be aware of the transform for
other purposes, such as input transformations. Also we want to provide
an implementation of the get_paint_volume virtual where Clutter will
also expect to be able to use the apply_transform virtual to transform
the volume into its parent's coordinate space.

This adds a verbose warning that will be displayed if

f5f066df9c Try to clean up how we handle actor transformations
When building actor relative transforms, instead of using the matrix
stack to combine transformations and making assumptions about what is
currently on the stack we now just explicitly initialize an identity
matrix and apply transforms to that.

This removes the full_vertex_t typedef for internal transformation code
and we just use ClutterVertex.

ClutterStage now implements apply_transform like any other actor now
and the code we had in _cogl_setup_viewport has been moved to the
stage's apply_transform instead.

ClutterStage now tracks an explicit projection matrix and viewport
geometry. The projection matrix is derived from the perspective whenever
that changes, and the viewport is updated when the stage gets a new
allocation. The SYNC_MATRICES mechanism has been removed in favour of
_clutter_stage_dirty_viewport/projection() APIs that get used when
switching between multiple stages to ensure cogl has the latest
information about the onscreen framebuffer.

e8e360eaa7 cookbook: Added a recipe for reusing a complex animation
This recipe explains how to "reuse" the same animation
definition for different actors, by creating a new
instance of a "rig" (empty container) and animation
for the rig each time the animation is required.

An actor is then re-parented to the rig and animated
using it, rather than being animated directly.

JSON is used to define the rig + animator, to make
creating new instances of them simpler. The recipe
also discusses various caveats around using this
approach, rather than directly animating an actor.
