Good question - I'm not sure, but I know it is at least consisitent 
within its platform. You may end up needing to create one equivocal 
image for each platform, in which case, the covering "image" would 
probably be a button with the icon set to the proper platform's 
equivocal image. I'd think you'd have to play around with it to see if 
there's any "pixel-creep", but you could make up for it by adjusting 
the image that's being put into the equivocal button (i.e. if you need 
the image to go down and to the left one pixel, you can add an empty 
pixel column on the left of the image, and an empty pixel row on the 
top of the image).
