Error occurs for certain layer orders when attempting to create AIA/LASCO

[Keith Hughitt]

When attempting to create a movie with AIA "on top" of LASCO, the video request fails, returning an error "error: index -9 out of array". When making the same request with LASCO on top of AIA, however, the request succeeds.
