This merge request adjust animations in the VolumeOSD and NotificationPopup to bring consistency and to make it feel better when swiping up a notification.
This fixes a bug where other sources dismissing the current popup notification would cause notifications in waiting to be assigned to the popup index of -1. This would cause these remaining notifications height to get set to a very thin strip at the top of the screen and would no longer automatically dismiss. This also fixes a bug where notifications in the popup drawer would become bunched up together at the top.
Implementation of a popup button to rotate the screen while using gesture navigation.
The button is set to appear when the device rotates while auto rotation is off. Then the button will be visible for a short period of time before disappearing.
