6a313ec2e2 Implemented clutter_actor_get_accessible
Added the implementation for clutter_actor_get_accessible, virtual
ClutterActor function, used to obtain the accessible object of
any ClutterActor.

As it is defined virtual, it would be possible to redefine it, so
any custom clutter actor could implement their accessibility object,
withouth relying totally on a accessibility implementation module.

See gtkiconview as example.

173e497ff4 state: Use Interval.compute() instead of compute_value()
Use the newly-added compute() variant to avoid creating a GValue only
for getting it copied by g_object_set_property().

af84d97fca interval: Add a pointer variant to compute_value()
ClutterInterval.compute_value() computes the new value given a progress
and copies it to a given GValue. Since most of the time we want to pass
that very same value to another function that copies it again, we should
have a compute_value() variant that stores that computed value inside
ClutterInterval and returns a pointer to it. This way we initialize the
result GValue just once and we never copy it, as long as the Interval
instance is valid.

bb2d088cb1 math: Adds an experimental cogl_vector3_* API
This adds a math utility API for handling 3 component, single precision
float vectors with the following; mostly self explanatory functions:

cogl_vector3_init
cogl_vector3_init_zero
cogl_vector3_equal
cogl_vector3_equal_with_epsilon
cogl_vector3_copy
cogl_vector3_free
cogl_vector3_invert
cogl_vector3_add
cogl_vector3_subtract
cogl_vector3_multiply_scalar
cogl_vector3_divide_scalar
cogl_vector3_normalize
cogl_vector3_magnitude
cogl_vector3_cross_product
cogl_vector3_dot_product
cogl_vector3_distance

Since the API is experimental you will need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h if you want to use
the API.

ee7ebe096e Stubs out _cogl_xlib_handle_event
This stubs out an xlib event handling mechanism for Cogl. The intention
is for Clutter to use this to forward all x11 events to Cogl. As we move
winsys functionality down into Cogl, Cogl will become responsible for
handling a number of X events: ConfigureNotify events for onscreen
framebuffers, swap events and Damage events for cogl_x11_texture_pixmap.

it still works to use the old names under EGL 1.3 so let's just use
those to keep compatibility.

4b239e1fe8 clutter-backend-egl: Chain up in dispose before destroying the context
clutter_backend_egl_dispose now chains up before disposing its own
resources so that ClutterBackendX11 will destroy all of the stages
before we destroy the egl context. Otherwise the actors may try to
make GL calls during destruction which causes a crash.

c4ae1a55fa fix case when EGL driver doesn't support EGL_NATIVE_VISUAL_ID
Some EGL drivers, such as the PowerVR simulator (and some proprietary drivers)
return zero when the EGLConfig is queried for the EGL_NATIVE_VISUAL_ID
attribute via eglGetConfigAttrib().

This patch detects and attempts to work around that situation by picking a
visual with the same color depth.

26b061c3a8 clutter-backend-egl: Create a dummy X window and EGL surface

backend introduced in d2c091e62.

4fd74e71e6 action: Add DragAction, an action implementing drag capabilities
DragAction is an Action sub-class that provides dragging capabilities to
any actor. DragAction has:

  • drag-begin, drag-motion and drag-end signals, relaying the event
    information like coordinates, button and modifiers to user code;

  • drag-threshold property, for delaying the drag start by a given
    amount of pixels;

  • drag-handle property, to allow using other actors as the drag
    handle.

  • drag-axis property, to allow constraining the dragging to a specific
    axis.

An interactive test demonstrating the various features is also provided.

A typed container for ActorMeta instances is also provided to the
sub-classes can be attached to an Actor.
