A more specific question--is all the Java support and overhead present when i use QC, even
if I have no use for it?

The support is there, probably lazily loaded (so not really, unless something makes use of it). memory-wise, the same -- likely not loaded unless something else touches it. Core Image filters do a bit with javascript, so that may cause it to get loaded etc.

As for CPU overhead, none at all -- QC doesn't appear to have any per- frame dependance upon JS aside from the JS patch (a good thing ;). It's loaded via the ExtraPatches.plugin bundle. with CoreImage filters, I'm not sure whether or not that's evaluated by default (I've not profiled/inspected that aspect of filtering) -- but if you make a more elaborate filter function, it's almost certainly evaluated per- frame. :(
