/**
* Control whether algorithmic darkening is allowed.
*
*
* Note: This API and the behaviour described only apply to apps with
* {@code targetSdkVersion} ≥ {@link android.os.Build.VERSION_CODES#TIRAMISU}.
*
*
* WebView always sets the media query {@code prefers-color-scheme} according to the app's
* theme attribute {@link android.R.styleable#Theme_isLightTheme isLightTheme}, i.e.
* {@code prefers-color-scheme} is {@code light} if isLightTheme is true or not specified,
* otherwise it is {@code dark}. This means that the web content's light or dark style will
* be applied automatically to match the app's theme if the content supports it.
*
*
* Algorithmic darkening is disallowed by default.
*
* If the app's theme is dark and it allows algorithmic darkening, WebView will attempt to
* darken web content using an algorithm, if the content doesn't define its own dark styles
* and doesn't explicitly disable darkening.
*
*
* If Android is applying Force Dark to WebView then WebView will ignore the value of
* this setting and behave as if it were set to true.
*
*
* The deprecated {@link #setForceDark} and related API are no-ops in apps with
* {@code targetSdkVersion} ≥ {@link android.os.Build.VERSION_CODES#TIRAMISU},
* but they still apply to apps with
* {@code targetSdkVersion} < {@link android.os.Build.VERSION_CODES#TIRAMISU}.
*
*
* The below table summarizes how APIs work with different apps.

* Web content which uses {@code prefers-color-scheme}
* Web content which does not use {@code prefers-color-scheme}

* Renders with the light theme defined by the content author.
* Renders with the default styling defined by the content author.
*
*
* App with Android forceDark in effect
* Renders with the dark theme defined by the content author.
* Renders with the styling modified to dark colors by an algorithm
* if allowed by the content author.
*
*
* App with {@code isLightTheme} False,
* {@code targetSdkVersion} < {@link android.os.Build.VERSION_CODES#TIRAMISU},
* and has {@code FORCE_DARK_AUTO}
* Renders with the dark theme defined by the content author.
* Renders with the default styling defined by the content author.
*
*
* App with {@code isLightTheme} False,
* {@code targetSdkVersion} ≥ {@link android.os.Build.VERSION_CODES#TIRAMISU},
* and {@code setAlgorithmicDarkening(false)}
* Renders with the dark theme defined by the content author.
* Renders with the default styling defined by the content author.
