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