-   * @description:
-   *   Controls experimental support of variable COLRv1 and whether the COLRv1
-   *   implementation should take into account variation deltas. This tells the
-   *   COLRv1 API methods whether they should read from the font and apply
-   *   variable deltas to COLRv1 properties. The feature is default off.  When
-   *   on, variable COLRv1 deltas are applied for COLRv1 features for which they
-   *   are already implemented. When off, variable deltas are ignored even if
-   *   the respective PaintVar* table may already be understood.
-   *
-   *   WARNING: Temporary flag during development of variable COLRv1. This flag
-   *   will be removed, do not rely on it. Full variable COLRv1 support will be
-   *   announced separately.
-   *
-   * @note:
-   *   This property cannot be set via the `FREETYPE_PROPERTIES` environment
