Revert all the work that happened on the master branch.
Sadly, this is the only way to merge the current development branch back
into master.
It is now abundantly clear that I merged the 1.99 branch far too soon,
and that Clutter 2.0 won't happen any time soon, if at all.
Since having the development happen on a separate branch throws a lot of
people into confusion, let's undo the clutter-1.99 → master merge, and
move back the development of Clutter to the master branch.
In order to do so, we need to do some surgery to the Git repository.
First, we do a massive revert in a single commit of all that happened
since the switch to 1.99 and the API version bump done with the
89a2862b05 commit. The history is too long
to be reverted commit by commit without being extremely messy.

|
* @short_description: Implementation of the ATK interfaces for a #ClutterClone
|
|
* @see_also: #ClutterClone
|
|
*
|
|
* #CallyClone implements the required ATK interfaces of #ClutterClone
|
|
*
|
|
* In particular it sets a proper role for the clone, as just a image,
|
|
* as it is the sanest and simplest approach.

|
/* Design rationale for CallyClone:
|
|
*
|
|
* In the old times, it was just ClutterCloneTexture. So, from a a11y POV
|
|
* CallyCloneTexture was just another image, like ClutterTexture, and if
|
|
* it was a clone was irrevelant. So on cally-0.8, CallyCloneTexture
|
|
* expose a object with role ATK_ROLE_IMAGE. But now, ClutterClone is more
|
|
* general. You can clone any object, including groups, and made things
|
|
* like have one text entry, and a clone with different properties in the
|
|
* same window, updated both at once.
|
|
*
|
|
* The question is if the idea is have a ClutterClone as a "first-class"
|
|
* citizen inside the stage hierarchy (full clone), or it is just supposed
|
|
* to be a mirror image of the original object.
|
|
*
|
|
* In the case of the a11y POV this would mean that if the text changes on
|
|
* the source, the clone should emit as well the text-changing signals.
|
|
*
|
|
* As ClutterClone smartly just paint the same object with different
|
|
* parameters, this would mean that it should be the cally object the one
|
|
* that should replicate the source clutter hierarchy to do that,
|
|
* something that just sound crazy.
|
|
*
|
|
* Taking into account that:
|
|
*
|
|
* - ClutterClone doesn't re-emit mirrored signals from the source
|
|
* I think that likely the answer would be "yes, it is just a
|
|
* mirrored image, not a real full clone".
|
|
*
|
|
* - You can't interact directly with the clone (ie: focus, and so on).
|
|
* Its basic usage (right now) is clone textures.
|
|
*
|
|
* Any other solution could be overwhelming.
|
|
*
|
|
* I think that the final solution would be that ClutterClone from the
|
|
* a11y POV should still be managed as a image (with the proper properties,
|
|
* position, size, etc.).
