Parasites:
Is there a philosophical reason that parasite changes are not
UNDOable? If not, could someone provide a nudge on how "non-tile"
information is saved to the UNDO history (for example, layer name
changes)?
Also, the "*-parasite-find" PDB functions return a list containing a
single list: for example,
(("gimp-comment" 1 #18"4372656174656420776974682047494d5000"))
There does not appear to be a way to create multiple parasites with
the same name -- the "*-parasite-attach" function changes the value of
the existing parasite. Is there a reason for the parasite to be
enclosed doubly within a list?
Tattoos:
If an object has a specific tattoo assigned to it then, when the
object is destroyed, is the tattoo value made available for re-use?
For example, I have three layers and record their tattoos. I then
merge those layers which generates a new layer (with a new tattoo).
Can I rely on the tattoos of the original layers not being assigned to
a new object (during that image editing session)? (If so, I would like
to assign the original tattoo to the merged layer.)
Or, is there a way to test a value to see if it is already attached to
an object?
