The layout preview/editor doesn't instantiate an Application instance, therefore accessing `displayMetrics` from the app context would lead to a crash, and the view being mocked in the preview.
Additionally a default grid value is defined for `AlignmentGridView` to avoid a crash because of an invalid iteration step in the drawing loop.
As part of this commit, a `defaultEnabled` property was added to `OnScreenButton` to determine the default visibility of buttons. This is required because L3 and R3 should be hidden by default and only enabled by the user on demand.
Additionally, the buttons' mask values were added to `ButtonId` members, as adding entries in the middle of the class conflicted with the `ordinal` enum property, making it unfit to use for our purposes.
Finally, the `ControllerType` class was extended with an array of optional buttons. Optional buttons represent buttons that are allowed to be displayed on screen, but shouldn't be included in the controller mapping activity.
Edit mode configuration parameters are now shared between the view and the buttons in a small `OnScreenEditInfo` object, avoiding variable duplication about edit state. The `editingTouchHandler` has also been simplified to only lookup the button if one wasn't being edited already.
`PreferenceDialogFragment`s have been extended to use `MaterialAlertDialogBuilder`, which results in Material Design 3 dialogs. `DialogFragment` creation logic has been moved to `SettingsActivity` to reduce code duplication.
`One missing Bitmap to rule them all and one condition to find them.` Also eliminates passing that condition between methods. The data class can simply return the same instance every time it's necessary.
Since this is instantiated in `onCreate` and may be recycled with different settings, relying on the audio to be disabled to determine if a mute action is available seems like a risky gamble.
This should adapt to the package name, despite not actually relying on the value of it to function. Intents are one of the most analyzed items for vulnerabilities and exploits.
* Add bold text and antialiasing for osc buttons
* Fix osc dpad and button position (widder than taller)
* Set default OSC color to white background with black text
