That makes sense: the problem does not show up with xetex.jpg (from 
XeTeX Samples) which is 72dpi, but becomes visible with the JPEG file 
created by Illustrator which is 300dpi.

I just checked with 300dpi TIFF and BMP (my Illustrator 10 does not 
know PNG): the size of the output is the same as with JPEG.
