List of changes since Clutter 1.6

Cogl moved out of tree

The Clutter OpenGL abstraction API has been moved to a separate repository and can be used as a stand-alone shared library for GPU programming. Clutter has been modified to depend on Cogl's experimental API.

Added ClutterGestureAction and ClutterSwipeAction

ClutterGestureAction is a generic "pointer gesture" action; it doesn't provide an implementation: it's up to the developer to add the gesture recognition code. ClutterSwipeAction is a GestureAction sub-class that implements the "swipe" gesture. The GestureAction API is already future proof for multi-device/multi-touch, even though the multi-touch isn't currently implemented.

Allow connecting signals to ClutterState states in ClutterScript

When defining a scene using ClutterScript it's possible to directly connect a state inside a ClutterState object (both defined in ClutterScript or in code) to an object's signal, without using an explicit signal handler in the code.

Add ClutterDropAction

The ClutterDropAction is an action for allowing ClutterActors to react when an actor being dragged through ClutterDragAction crosses, or is dropped over, them.

Mark the OSX backend as non-experimental

The OSX backend is being developed, and maintained, so it should not be considered experimental.

ImproveClutterCairoTexture

Make drawing using Cairo on a ClutterCairoTexture easier to implement, by removing the requirement of handling the cairo_t context manually, and by using invalidations and signals.

Documentation fixes

New recipes were added to the Cookbook, and example code was added in the API reference of various classes.

List of changes since Clutter 1.7.90

Add debug options to catch out-of-band transformations

Transformations performed outside of the ::apply_transform() virtual function are problematic for Clutter, as they might break paint volume, culling, and event handling. The "oob-transform" debug mode will add a check and a warning if the expected modelview matrix as computed by Clutter is not the current modelview matrix set when painting an actor. This debug mode should help when debugging some hard to pinpoint redraw issue.

Implicitly clip to the stage viewport

This should avoid degenerate clip regions.

Paint editable Text actors even when empty

If the cursor is visible we need to actually paint it.

Do not fall back to the text color for the selection color

This avoids invisible text in case the selected-text-color property is not set in ClutterText.

Add a fall back to wildcard source durations in ClutterState

This allows having wildcard sources to provide a duration for other transitions.

Translations updates

Indonesia, Lithuanian, Catalan, Tamil, Slovenian, Hindi, Kannada.

• 659069 - text: Take out a nonsense fallback
• 659116 - text: We still have to paint the actor if the cursor is visible
• 659200 - [PATCH] Use correct duration on ClutterState transitions with wildcard source
• 659501 - Queue a redraw when removing an effect by name
