I didnt want it to do anything really, just wanted to know what it did... what about those unit pixels thing? when the canvas is not gopped? cheers
it basically sets the resolution of the gop. you notice it if you use data
structures.
or even: create an array, and open the graphical subpatch. draw a wave,
and try around different values. (also for any other fields)
with donecanvasdialog, I use these to change the zoom of my data-s
patches, etc.
