This fixes an issue where if the device is rotated in a folder, the page would not snap immediately back to the right position, but would instead animate icon position changes.
To achieve this, the following changes were made.
- changes were made to how the folder gird size is calculated to prevent an issue with the grid size changing for a brief period of time during screen rotation, causing problems with snapping to the correct page.
- icons position animations are now done by a animated index value to prevent it from animating when the device rotates
- when the device screen size changes (ex: device rotation), it now snaps to the current folder page, as before it would just stay in between the two pages.
