The wrapper class for image objects.
MPImage is designed to be an immutable image container, which could be shared
cross-platforms.
To construct a MPImage, use the provided builders:
MPImage uses reference counting to maintain internal storage. When it is created the
reference count is 1. Developer can call close() to reduce reference count to release
internal storage earlier, otherwise Java garbage collection will release the storage eventually.
To extract concrete image, first check MPImage.StorageType and then use the provided
extractors:

Public Methods
public synchronized void close ()
Removes a reference that was previously acquired or init.
When MPImage is created, it has 1 reference count.
When the reference count becomes 0, it will release the resource under the hood.

public int getHeight ()
Returns the height of the image.
public int getWidth ()
Returns the width of the image.
