8e6fac38fa Don't update or use last_paint_box when painting inside a clone
The last_paint_box for an actor represents its "normal" position - we
shouldn't update it or use it to cull drawing if we are painting
a clone of the actor. Tracking whether we are painting a clone is
done by adding  _clutter_actor_push/pop_clone_paint() and a global
"clone paint level".

c68280556e clip-stack: combine modelview-projection in set_clip_planes
When using clip planes and we we have to project some vertices into
screen coordinates we used to transform those by the modelview and then
the projection matrix separately. Now we combine the modelview and
projection matrix and then use that to transform the vertices in one
step instead.

99f4832c28 journal: remove possability of fallback layers
When logging quads in the journal it used to be possible to specify a
mask of fallback layers (layers where a default white texture should be
used in-place of the corresponding texture in the current source
pipeline). Since we now handle fallbacks for cogl_rectangle* primitives
when validating the pipeline up-front before logging in the journal we
no longer need the ability for the journal to apply fallbacks too.

305bb124b7 use cogl_matrix_transform_points in clutter
When transforming a paint-volume or transforming allocation vertices we
are transforming more than one point at a time so we can batch those
together with cogl_matrix_transform_points instead of
cogl_matrix_transform_point. Also in both of these cases we don't need
to do a projective transform so using cogl_matrix_transform_points also
lets us reduce the per-vertex computation.

2dba3e8cbf matrix: Adds experimental cogl_matrix_{transform,project}_points
This add two new function that allows us to transform or project an
array of points instead of only transforming one point at a time. Recent
benchmarking has shown cogl_matrix_transform_point to be a bottleneck
sometimes, so this should allow us to reduce the overhead when
transforming lots of vertices at the same time, and also reduce the cost
of 3 component, non-projective transforms.

For now they are marked as experimental (you have to define
COGL_ENABLE_EXPERIMENTAL_API) because there is some concern that it
introduces some inconsistent naming. cogl_matrix_transform_point would
have to be renamed cogl_matrix_project_point to be consistent, but that
would be an API break.

4307e65f93 primitives: validate with _cogl_pipeline_foreach_layer
Switch _cogl_rectangles_with_multitexture_coords to using
_cogl_pipeline_foreach_layer to iterate the layers of a pipeline when
validating instead of iterating the pipelines internal list, which is
risky since any modifications to pipelines (even to an override pipeline
derived from the original), could potentially corrupt the list as it is
being iterated.

fb564cc2ca cogl: remove WrapModeOverrides from FlushOptions
This removes the possibility to specify wrap mode overrides within a
CoglPipelineFlushOptions struct since the right way to handle these
overrides is by copying the user's material and making the changes to
that copy before flushing. All primitives code has already switched away
from using these wrap mode overrides so this patch just removes unused
code and types. It also remove the wrap_mode_overrides argument for
_cogl_journal_log_quad.

ab6da347f6 color: Support CSS color definitions
The CSS Color Module 3, available at:

  http://www.w3.org/TR/css3-color/

allows defining colors as:

  rgb ( r, g, b )
  rgba ( r, g, b, a)

along with the usual hexadecimal and named notations.

The r, g, and b channels can be:

  • integers between 0 and 255
  • percentages, between 0% and 100%

The alpha channel, if included using the rgba() modifier, can be a
floating point value between 0.0 and 1.0.

The ClutterColor parser should support this notation.

1299672b5a Actually free buffer objects
With the refactoring to centralize code into CoglBuffer,
_cogl_buffer_fini() was never actually implemented, so all GL
vertex and index buffer objects were leaked.

The duplicate call to glDeleteBuffers() in CoglPixelArray is
removed (it wasn't paying attention to whether the buffer had been
allocated as a PBO or not.)

a5c30398df egl: Adds support for clipped redraws
This adds egl backend support for handling clipped redraws. This uses
the EGL_NOK_swap_region extension to enable the EGL backend to present a
subregion from the back buffer to the front so we don't always have to
redraw the entire stage for small updates.

It also works for indexed vertex arrays.

78ac92f8e5 vertex-buffer: don't unref NULL object

f473c213fc vertex-array: Adds data arg for _vertex_array_new()
This adds an optional data argument for cogl_vertex_array_new() since it
seems that mostly every case where we use this API we follow up with a
cogl_buffer_set_data() matching the size of the new array. This
simplifies all those cases and whenever we want to delay uploading of
data then NULL can simply be passed.

a94ea93bde paint-volume: Do not take a reference on the actor
The paint volume structure is cached in the Actor it references, and
this causes a reference cycle.

The paint volume is going to be used when painting, so the actor must
still be valid - otherwise Clutter will bail out far before than
accessing the actor pointer in ClutterPaintVolume.

Otherwise, we could have used dispose() to check for a valid actor and
remove a reference if the actor field is !NULL; it feels less clean,
though, since we're effectively managing an extra reference on
ourselves.

b55346151c build: Cogl-2.0 API reference should be conditionally built
Building the API reference for Cogl 2.0 is fairly confusing: the API
itself is experimental and for internal use only -- though we want
feedback for it.

Let's build the API reference only when Clutter is configured with a
specific configure switch, so that people that wish to give feedback on
the API and its documentation can do it.

8f60d5a3a2 Start using the monotonic API in GLib ≥ 2.27
Starting from the 2.27 cycle, GLib is exposing a monotonic clock with
microseconds granularity throughout the time-based API. We can start
using it, given that the old, non-monotonic version is going to be
deprecated by the same cycle.

68d7a5e847 Move away from GTimeVal
GLib 2.28 will deprecate GTimeVal and related API in favour of
standardizing on microseconds granularity for all time-based API.

Clutter should switch too.

All of the current users of GTimeVal convert to milliseconds when
doing time operations, and use GTimeVal only as storage. This can
effectively be replaced by a gint64.

The Master Clock uses a microsecond resolution, except when interacting
with the main loop itself, since the main loop has a millisecond
resolution - at least until Ryan Lortie manages to switch that too to
microseconds on Linux.

The clutter_timeline_do_tick() function was erroneously not privatized,
but it was still assumed to be private; we should just remove it from
the public symbols.
