13/**
14 * A wrapper drawable to square the wrapped drawable so that it expands to fill a square with exactly the given side
15 * length. The goal of this drawable is to ensure that square thumbnail drawables always match the size of the view
16 * they will be displayed in to avoid a costly requestLayout call. This class should not be used with views or drawables
17 * that are not square.
