Impress and Calc used to dump the same image file
as many times as it was featured in the document,
resulting redundant, sometimes huge documents.
Note: using only checksum to recognize image duplication
is a regression, because checksum collision results
image loss. This is a very unlikely event, and
the following commits have got the same problem.
The solution is comparing the images with the same
checksum byte for byte.
