bb93a98762 [clutter-color] Use a different hls->rgb algorithm + use floating point
Using test-cogl-vertex-buffer as a test case which is CPU bound due to
hls -> rgb conversions this alternative algorithm looked to be ~10%
faster when tested on an X61s Lenovo.

567a96c96a [docs] More information on animation queueing
Queuing an animation on an actor cannot be done from within the
::completed signal handler, because we guarantee that the Animation
instance is valid and attached to the actor it animates for the
whole duration of the signal emission chain.

In order to queue animations you have to install an idle handler
on the main loop, and call clutter_actor_animate() inside it.

The documentation should be more clear about this caveat in the
memory management of ClutterAnimations created by the animate()
family of functions.

ca3bfe2cea [cogl] Don't endlessly print the same warning regarding layer fallbacks
There are various constraints for when we can support multi-texturing and
when they can't be met we try and print a clear warning explaining why the
operation isn't supported, but we shouldn't endlessly repeat the warning for
every primitive of every frame. This patch fixes that.

c5bd63648d [tests] Adds an interactive cogl vertex buffer unit test
The test is a sanity check that dynamic updating of vertex data via the cogl
vertex buffer api works and has reasonable performance. (though it can't be
considered a well designed benchmark since it wastes casual amounts of CPU
time simply choosing pretty colors.)

The code also aims to demonstrate one way of creating, updating and efficiently
drawing a quad mesh structure via the vertex buffer api which could be applied
to lots of different use cases.

075ae9c4a7 [cogl-vertex-buffer] Add a flush of attribute changes in the *_draw() functions
For convenience it is now valid to avoid a seperate call to
cogl_vertex_buffer_submit() and assume that the _draw() calls will do this
for you (though of course if you do this you still need to ensure the
attribute pointers remain valid until your draw call.)

a93a93d007 Count timeline frames using the FPS instead of an integer interval
Bug 1495 - Timelines run 4% short

Previously the timelines were timed by calculating the interval
between each frame stored as an integer number of milliseconds so some
precision is lost. For example, requesting 60 frames per second gets
converted to 16 ms per frame which is actually 62.5 frames per
second. This makes the timeline shorter by 4%.

This patch merges the common code for timing from the timeout pools
and frame sources into an internal clutter-timeout-interval file. This
stores the interval directly as the FPS and counts the number of
frames that have been reached instead of the elapsed time.

216373047b [animation] Enhance consistency of the Animation API
The Animation API should follow this pattern:

  - functions with an Interval as part of the arguments should have
    "interval" inside their name, e.g.:

      clutter_animation_bind_interval
      clutter_animation_update_interval

  - functions dealing with property names should have "property"
    inside their name, e.g.:

      clutter_animation_has_property
      clutter_animation_unbind_property

    - unless -

  - functions dealing with a property and its value should not
    have any modifier, e.g.:

      clutter_animation_bind

The change from update_property() to update_interval() frees up
clutter_animation_update(), to be added at a later date.

5706105123 [actor] Add :clip-to-allocation property
A common use of setting clip is to keep an actor inside its allocation;
right now to do this you have to set up a callback on notify::allocation.

There's no overhead added by sticking another bit in ClutterActor
clip-to-allocation that will clip painting to the allocation if set.

0cb0a841cc [animation] Enhance the bind API
Bug 1419 - Add clutter_animation_bind, rename clutter_animation_bind_interval

This is a different approach from the clutter_actor_animatev
vector variant.  The single call should be even easier on
automatic bindings, since calls can be chained like:

  new Clutter.Animation({object: myactor}).bind("x", 42).bind("y", 43);

Note clutter_animation_bind_property which took a ClutterInterval
is renamed to clutter_animation_bind_interval for clarity, and to
discourage use since there are friendlier APIs about.

e1742af368 Avoid drawing twice if relayout queues a draw
It's reasonably normal for a relayout of the stage to cause the stage
to be queued for drawing; for this reason we should do the relayout before
we clear stage->update_idle. (But want to clear update_idle() before actually
doing the redraw to handle the corner case where the draw queues another
redraw.)

72f9646804 Do not cause more size requisitions than necessary
Bug 1499 - clutter_actor_notify_if_geometry_changed causes sync
           layout cycles

Whenever clutter_actor_set_{width,height,x,y,size...} is used, extra
synchronous size requests are triggered in
clutter_actor_notify_if_geometry_changed.

If the get_preferred_width() and get_preferred_height() implementations
are particularly costly (e.g. ClutterText) this will result in a performance
impact.

To avoid excessive allocation or requisition cycles we use the
cached values and flags. If we don't have an allocation, we assume
that we need to notify all the properties; if we don't have a size
requisition we notify only width and height; finally, if we do have
a valid allocation we notify only on the changed values.

0d88ecb459 Avoid casting CoglMatrix to a GLfloat * when calling glGetFloatv
If we later add internal flags to CoglMatrix then this code wouldn't

if that turns out to be something worth optimizing we can look again at
using a cast but adding another way for initializing internal flags.
