I don't know who makes pageview, but they're wrong.  GhostScript and GoScript
both clear the page on showpage, and of course printers print the page on
showpage.

The Adobe Blue Book says 

- _showpage_ -      output and reset current page
- _copypage_ -      output current page
- _erasepage_ -     paint current page white

You could work around the problem with erasepage, but there should be no need.
pageview should be clearing on showpage.

Whose is it, btw?  Sun's?
