    I still like the idea of having a reference count for an efficient use of
    memory. Without a count, the printer really has to keep all the images in
    memory is some way until the end of the last page of the document. There
    are other memory problems with the declare attribute besides the need to
    keep images around until the end of the doc. Using the declare attribute
    along with another instance where the image is in the data attribute may
    cause the image to be truncated due to memory constrains when doing
    attribute parsing.
