Window Management - Implement maximize and semi-maximise transitions

Both of these animations are simply not possible right now. Getting a
preview of a window at a different size requires resizing the window,
which if done today would be a giant hack that would likely result in
unpredictable bugs. Animations cannot rely on being able to render the
window at multiple sizes.

I wasn't able to look at the videos (missing plugins), but I don't
think that these are impossible per-se. If the videos are showing
windows resizing the content, then we need an XComposite patch create
temporary large pixmaps (or at least a pixmap of a new size) and
resize the window inside of that pixmap. This massively increases
binding speed on the nvidia driver and others.

Otherwise it is possible to do in-compiz by copying the old window
texture into temp memory, and stretching the old texture, fading it
out and fading through the new texture.

The video in short shows the window at two sizes at the same time.

I doubt we want full preview of the maximise and semi-maximise windows.
Outline seems more appropriate. I am offline but will check the videos
later.

Having seen the movie I think we should focus on a classy outline
approach first, then come back to a blurred preview (snapshot in time)
in a future iteration.

Description from duplicate bug entered by Charline after conducting the Natty user testing:

--------------------------------

Usability testing has shown that participants misinterpret the semi-maximise and maximise gesture previous shadow as a warning to stop their action. They do not understand the correlation between this gesture preview and semi-maximising and maximising the window.

Desired solution:
- implement the maximise and semi-maximise transitions as illustrated in the animations provided by design.
- see https://chinstrap.canonical.com/~johnlea/transitions/1104unity_elements/maximise_gesture_preview.mov
- see https://chinstrap.canonical.com/~johnlea/transitions/1104unity_elements/maximise_gesture_preview.mov
- This gesture preview does not need to be live. A cached snapshot of the window can be stretched as a performance optimisation.

It is not very encouraging to know that we need to be authenticated to watch a preview, especially as active community members.

Why can't i view these movies even when i'm logged in? it tells me i'm unauthorized.. :(

The movies are now attached ;-)

@rolandixor @coder543: this is a know issue. See this thread: https://lists.launchpad.net/ayatana-dev/msg00167.html

When are the effects shown in the videos are coming to Ubuntu? In Oneiric with all the newest updates (proposed included) I still have the orange rectangle preview like in Natty.

At what point will the window be considered set to maximize/semi-maximize? For natty it had that incremental approach and it was confusing as to when/if it would be registered as a maximize gesture. For oneiric there is none, giving a simple "yes or no" answer. Will the mockup be implemented in the current Oneiric approach?

news?
code, package, integration in Precise?

Is this going to be available in Precise?

>> Is this going to be available in Precise?
no

Tip for anxious people: when a bug is milestoned "backlog", it means that it is delayed until more urgent bugs get fixed. So don't hold your breath! :)

This bug was fixed in the package compiz - 1:0.9.9~daily13.01.21-0ubuntu1
