This is a bug that was introduced in Leopard that affects PDF and EPS 
images. I don't believe there's any way to coerce the attachment (or 
the NSImage even) to not use the cached (low quality) image data. You 
have to tell the NSImageRep draw itself directly to avoid the issue.

Pages uses WebKit, not NSTextView and friends.
