BitmapTransformation
Bitmap
based on the given dimensions and returns
the transformed result.
The provided Bitmap, toTransform, should not be recycled or returned to the pool. Glide will automatically recycle and/or reuse toTransform if the transformation returns a different Bitmap. Similarly implementations should never recycle or return Bitmaps that are returned as the result of this method. Recycling or returning the provided and/or the returned Bitmap to the pool will lead to a variety of runtime exceptions and drawing errors. See #408 for an example. If the implementation obtains and discards intermediate Bitmaps, they may safely be returned to the BitmapPool and/or recycled.

this class converts them to be the size of the Bitmap we're going to transform before calling
this method.
