/**
 * A {@link TextView} which supports compatible features on older versions of the platform,
 * including:
 * <ul>
 * <li>Allows dynamic tint of its background via the background tint methods in
 * {@link androidx.core.view.ViewCompat}.</li>
 * <li>Allows setting of the background tint using
 * {@link androidx.appcompat.R.attr#backgroundTint} and
 * {@link androidx.appcompat.R.attr#backgroundTintMode}.</li>
 * <li>Supports auto-sizing via {@link androidx.core.widget.TextViewCompat} by allowing to instruct
 * a {@link TextView} to let the size of the text expand or contract automatically to fill its
 * layout based on the TextView's characteristics and boundaries. The style attributes associated
 * with auto-sizing are
 * {@link androidx.appcompat.R.attr#autoSizeTextType},
 * {@link androidx.appcompat.R.attr#autoSizeMinTextSize},
 * {@link androidx.appcompat.R.attr#autoSizeMaxTextSize},
 * {@link androidx.appcompat.R.attr#autoSizeStepGranularity} and
 * {@link androidx.appcompat.R.attr#autoSizePresetSizes}, all of which work back to
 * {@link VERSION_CODES#ICE_CREAM_SANDWICH Ice Cream Sandwich}.</li>
 * </ul>
 *
 * <p>This will automatically be used when you use {@link TextView} in your layouts
 * and the top-level activity / dialog is provided by
 * <a href="{@docRoot}topic/libraries/support-library/packages.html#v7-appcompat">appcompat</a>.
 * You should only need to manually use this class when writing custom views.</p>
