/**
|
|
* This test ensures that the VM gracefully handles a sprite3 file with
|
|
* a missing bitmap costume. The VM should handle this safely by displaying
|
|
* a Gray Question Mark, but keeping track of the original costume data
|
|
* and serializing the original costume data back out. The saved project.json
|
|
* should not reflect that the costume is broken and should therefore re-attempt
|
|
* to load the costume if the saved project is re-loaded.
