Movieclip: Use first clip frame for size detection

Using scene frame 1 is not reliable in cases when there is a
frame offset is involved. Using frame 1 seems more reliable,
although might still fail under certain circumstances.

More reliable fix would require a deeper change in the data
structure and the logic about frame loading and size detection.
