Bug Description

Implement maximize and semi-maximise transitions

Description:

The window maximize and semi-maximize functionality has already been built, however the 'gesture previews' and transitions need to be perfected. Attached are two animations that show the desired 'gesture preview'. Note the behavior when the user backs away from the gesture preview without releasing the window.

The following art assets are linked from this bug:

Note from 12.04 user testing

Participants found that the current 12.04 maximise and semi-maximise transitions are unpredictable and the preview (the orange highlight box) is confusing.
