Expose CJBig2_Image::ComposeTo() as a public method.
CJBig2_Image::ComposeFrom() wraps a call to ComposeTo() and does an
extra validity check. In tight loops where the validity check will
always succeed, this is wasteful. Change existing callers of
ComposeFrom() to ComposeTo() when the validity check has already been
done.
