Returns the entire image in a single Raster.  For images with
multiple tiles this will require making a copy.

<p> The returned Raster is semantically a copy.  This means
that updates to the source image will not be reflected in the
returned Raster.  For non-writable (immutable) source images,
the returned value may be a reference to the image's internal
data.  The returned Raster should be considered non-writable;
any attempt to alter its pixel data (such as by casting it to
WritableRaster or obtaining and modifying its DataBuffer) may
result in undefined behavior.  The copyData method should be
used if the returned Raster is to be modified.

@return a Raster containing a copy of this image's data.
