That's great.  I think "setbounds" is a much better name than "relocate"; 
it has a straightforward connection to the arguments (unlike "relocate").

Is there any way to have the iemgui messages "pos" and "delta" for 
canvases?  For example, if I have a canvas with a bunch of subpatches 
that all have different sizes, but I want to move them all up to the 
top left-hand corner or the screen, "pos 0 0" would be really handy.
