Stick regions extend the activation area of the sticks to rectangles covering the corresponding half of the screen.
E.g. for the left stick: when any point of the left side of the screen is touched, the stick is repositioned there, and acts as if it was centered in the touched position. When the finger is lifter, the stick is hidden.
`PreferenceSettings` was removed in favor of:
* `AppSettings`: stores general purpose settings mostly used for UI configuration and state
* `EmulationSettings`: stores emulation-related settings, most of these are passed to native emulation code
SharedPreferences will be partially swapped out in the future to support per-game settings. In the meantime, make it clear from which class settings are coming from.
Any `RecyclerView`s with an app bar in a `CoordinatorLayout` would end up going off-screen due to the layout behavior implementing an offset by using a transform which would not correctly handle focusing on off-screen objects. This has now been fixed by manually adjusting height to be clipped to what is visible on the screen.
If the controller type was changed from a type with a larger amount of buttons/axes to one with a fewer amount, a crash would occur due to the transition animation retaining those elements as children yet returning `NO_POSITION` from `getChildAdapterPosition` in `DividerItemDecoration` which was an unhandled case and led to an OOB array access.
Dividers after titles were missing in `ControllerActivity` which made it look inconsistent with `SettingsActivity` which did have them. They have now been added by extending `DividerItemDecoration` to be drawn before any `ControllerHeaderItem`.
This fixes a Joy-Con Pair bug which caused a crash when a partner device was set to none while being set as a partner. In addition, the following HID service functions were implemented:
* GetSupportedNpadStyleSet
* ActivateNpadWithRevision
* GetNpadJoyHoldType
* AcquireNpadStyleSetUpdateEventHandle
This commit adds in the UI for Controller Configuration to Settings, in addition to introducing the storage and loading of aforementioned configurations to a file that can be saved/loaded at runtime. This commit also fixes updating of individual fields in Settings when changed from an external activity.
