In order to support rotated thumbnails based off the device orientation,
we should create a custom drawable that supports drawing a rotated
bitmap based off some requested orientation. This CL adds this class,
and we'll use it in a later CL.
By baking this directly into the drawable, we prevent unnecessary
allocations of rotated bitmaps.
