public static booleanisPublicFormat(int format)
Determine whether or not this is a public-visible and non-deprecated {@code format}.

In particular, {@code @hide} formats will return {@code false}.

Any other indirect formats (such as {@code TRANSPARENT} or {@code TRANSLUCENT}) will return {@code false}.
