bf9d5f3949 build: distinguish CLUTTER_WINSYS and CLUTTER_SONAME_INFIX
This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.

For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.

0411ba7d32 actor: Parse actions, constraints and effects members
ClutterActor should allow attaching actions, constraints and effects
just like it allows behaviours, e.g.:

  {
    ...
    "constraints" : [
      {
        "type" : "ClutterAlignConstraint",
        "source" : "stage",
        "align-axis" : "x-axis",
        "factor" : 0.5
      },
      {
        "type" : "ClutterAlignConstraint",
        "source" : "stage",
        "align-axis" : "y-axis",
        "factor" : 0.5
      }
    ],
    ...
  }

or:

  {
    ...
    "actions" : [
      {
        "type" : "ClutterDragAction",
        "signals" : [
          { "name" : "drag-end", "handler" : "on_drag_end" }
        ]
      }
    ],
    ...
  }

In order to do so, we use the Scriptable interface implementation and
add three new custom properties accepting an array; then we parse each
member of the array as a new object.

2d99f77e3b cairo-texture: Disable :sync-size
The :sync-size property of ClutterTexture should be set to FALSE by
default by ClutterCairoTexture. The preferred size of the
ClutterCairoTexture is already the size of the internal Cairo surface,
and we override the preferred width/height getters to that effect.

The :sync-size property is also responsible of changing the size of
the Texture actor when changing the texture handle - but since we
encourage that to happen during the CairoTexture allocation, we get a
queue_relayout() invocation (and a warning) when we change the size
of the Cairo image surface.

Since GObject doesn't make it easy to override the default value of the
:sync-size property in sub-classes, we should simply call the setter
function during the ClutterCairoTexture instance initialization.

We should also change one of the interactive tests using a CairoTexture
to rebuild the contents of the actor in response to an allocation.

c434f1fc48 material: Make CoglMaterial responsible for depth state
This redirects the legacy depth testing APIs through CoglMaterial and
adds a new experimental cogl_material_ API for handling the depth
testing state.

This adds the following new functions:
cogl_material_set_depth_test_enabled
cogl_material_get_depth_test_enabled
cogl_material_set_depth_writing_enabled
cogl_material_get_depth_writing_enabled
cogl_material_set_depth_test_function
cogl_material_get_depth_test_function
cogl_material_set_depth_range
cogl_material_get_depth_range

As with other experimental Cogl API you need to define
COGL_ENABLE_EXPERIMENTAL_API to access them and their stability isn't
yet guaranteed.

4c22f122e1 script: Support layout manager properties
Layout properties work similarly to child properties, with the added
headache that they require the 3-tuple:

  ( layout manager, container, actor )

to be valid in order to be inspected, parsed and applied. This means
using the newly added back-pointer from the container to the layout
manager and then rejigging a bit how the ScriptParser handles the
unresolved properties.

Similarly to the child properties, which use the "child::" prefix, the
layout manager properties use the "layout::" prefix and are defined with
the child of a container holding a layout manager.

a86f1b45bb Add the ClutterEffect abstract class
ClutterEffect is an abstract class that should be used to apply effects
on generic actors.

The ClutterEffect class just defines what an effect should implement; it
could be defined as an interface, but we might want to add some default
behavior dependent on the internal state at a later point.

The effect API applies to any actor, so we need to provide a way to
assign an effect to an actor, and let ClutterActor call the Effect
methods during the paint sequence.

Once an effect is attached to an actor we will perform the paint in this
order:

  • Effect::pre_paint()
  • Actor::paint signal emission
  • Effect::post_paint()

Since an effect might collide with the Shader class, we either allow a
shader or an effect for the time being.

ec59af290c analysis: None used in pointer context
While this is totally fine (None is 0L and, in the pointer context, will
be converted in the right internal NULL representation, which could be a
value with some bits to 1), I believe it's clearer to use NULL instead
of None when we talk about pointers.

589c8d9579 [texture] Support picking textures according to their alpha channel
This adds a boolean "pick-with-alpha" property to ClutterTexture and when
true, it will use the textures alpha channel to define the actors shape when
picking.

Users should be aware that it's a bit more expensive to pick textures like
this (so probably best not to blindly enable it on *all* your textures)
since it implies rasterizing the texture during picking whereas we would
otherwise just send a solid filled quad to the GPU.  It will also interrupt
the internal batching of geometry for pick renders which can otherwise often
be done in a single draw call.

728e2d8071 drag: Add a default drag-motion behaviour
The DragAction should, by default, drag the actor to which it has been
applied, instead of delegating what to do to the developer. If custom
code need to override it, g_signal_stop_emission_by_name() can be called
to stop the default handler to ever running.

ff7ce2c5b2 test-cogl-materials: Run the 'all layers' test with different prims
The drawing code from test_invalid_texture_layers which draws a
rectangle, a polygon and a vertex buffer has been split out to
separate function. test_using_all_layers now also uses this so that it
will also test the other two primitives. This causes the test to fail
when all of the layers are drawn using a vertex buffer.

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.
