Avoids extra calls to
android.view.View#requestLayout when loading more than once
image into an
android.widget.ImageView with fixed dimensions.
Typically it makes sense
to use this class when loading multiple images with the
com.bumptech.glide.RequestBuilder#thumbnail(com.bumptech.glide.RequestBuilder) API into views in
a scrolling list like ListView, GridView, or RecyclerView.
FixedSizeDrawable may cause skewing or other undesirable behavior depending on
your images, views, and scaling. If this occurs, consider
DrawableImageViewTarget or
BitmapImageViewTarget as alternatives.
