Shin Yamamoto	4904ea19cb	Fix the stiff animation of "show detail panel" panel. When a panel moves to tip position, the moving animation has been stiff. This issue has happened since Xcode 14.	2022-10-15 09:19:01 +09:00
Shin Yamamoto	b941f91556	Fix the backdrop alpha when the view size or its size class changes (#573 ) This fixes #572 to change the backdrop alpha when the view size or its size class changes. The main change is that `true` is passed as a `forceLayout` parameter into `viewWillTransition(to:with:)` callbacks. Because it's necessary for the backdrop alpha's update when the view size or its size class changes. This also fixes a regression at `9c45c31` commit. ```diff - layoutAdapter.activateLayout(for: state, forceLayout: true) + layoutAdapter.activateLayout(for: state, forceLayout: forceLayout) ``` The behavior before the above change indicates that the method has worked well even when `forceLayout` is set to `true` in their callbacks. Additional improvements: * Format `activateLayout(forceLayout:contentInsetAdjustmentBehavior:)` * Add `_floor` function for `test_updateBackdropAlpha()`	2022-10-15 09:06:14 +09:00
