Implements a generic ClutterActorClone that doesn't need fbos. Many use cases for clonning an actor don't require running a shader on the resulting clone image and so requiring FBOs in these cases is overkill and in-efficient as it requires kicking and synchronizing a render for each clone. This approach basically just uses the paint function of another actor to implement the painting for the clone actor with some fiddling of the model- view matrix to scale according to the different allocation box sizes of each of the actors. A simple unit test called test-actors2 was added for testing.

Remove Units from the public API With the recent change to internal floating point values, ClutterUnit has become a redundant type, defined to be a float. All integer entry points are being internally converted to floating point values to be passed to the GL pipeline with the least amount of conversion. ClutterUnit is thus exposed as just a "pixel with fractionary bits", and not -- as users might think -- as generic, resolution and device independent units. not that it was the case, but a definitive amount of people was convinced it did provide this "feature", and was flummoxed about the mere existence of this type. So, having ClutterUnit exposed in the public API doubles the entry points and has the following disadvantages: - we have to maintain twice the amount of entry points in ClutterActor - we still do an integer-to-float implicit conversion - we introduce a weird impedance between pixels and "pixels with fractionary bits" - language bindings will have to choose what to bind, and resort to manually overriding the API + *except* for language bindings based on GObject-Introspection, as they cannot do manual overrides, thus will replicate the entire set of entry points For these reason, we should coalesces every Actor entry point for pixels and for ClutterUnit into a single entry point taking a float, like: void clutter_actor_set_x (ClutterActor *self, gfloat x); void clutter_actor_get_size (ClutterActor *self, gfloat *width, gfloat *height); gfloat clutter_actor_get_height (ClutterActor *self); etc. The issues I have identified are: - we'll have a two cases of compiler warnings: - printf() format of the return values from %d to %f - clutter_actor_get_size() taking floats instead of unsigned ints - we'll have a problem with varargs when passing an integer instead of a floating point value, except on 64bit platforms where the size of a float is the same as the size of an int To be clear: the *intent* of the API should not change -- we still use pixels everywhere -- but: - we remove ambiguity in the API with regard to pixels and units - we remove entry points we get to maintain for the whole 1.0 version of the API - we make things simpler to bind for both manual language bindings and automatic (gobject-introspection based) ones - we have the simplest API possible while still exposing the capabilities of the underlying GL implementation

Allow passing the pick mode to get_actor_at_pos() Bug 1513 - Allow passing in ClutterPickMode to clutter_stage_get_actor_at_pos() At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL internally to find an actor. It would be useful to allow passing in ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller can specify CLUTTER_PICK_REACTIVE as a criteria.

Implements a generic ClutterActorClone that doesn't need fbos. Many use cases for clonning an actor don't require running a shader on the resulting clone image and so requiring FBOs in these cases is overkill and in-efficient as it requires kicking and synchronizing a render for each clone. This approach basically just uses the paint function of another actor to implement the painting for the clone actor with some fiddling of the model- view matrix to scale according to the different allocation box sizes of each of the actors. A simple unit test called test-actors2 was added for testing.

Improves the unit test to verify more awkward scaling and some corresponding fixes This simplifies the mucking about with the model-view matrix that was previously done which improves its efficiency when scaling is necessary. Notably: There should now be no performance advantage to using ClutterCloneTexture as a special case clone actor since this method is just as efficient. The unit test was renamed to test-actor-clone.

Rename ActorClone to Clone/2 Step two: rename the object and its methods. While we're at it, adhere more strictly to the coding style practises; rename :clone-source to :source; add a setter method for the :source property; take a reference on the source actor to avoid it disappearing while we're still accessing it.
