Of course, PostScript got this wrong in a lot of ways---for the
majority of users of PostScript, their language reads left to right,
top to bottom.  In particular, this causes problems when printing on
pages of different sizes.  You often see this when moving from A4 to
US Letter size, where things tend to get cut off because 0,0 is too
close to the bottom of the page.

Also note that much cruft was installed in Display PostScript to allow
flipped coordinate systems where 0,0 is top left.

I don't see this as a big issue, but most of the text we're likely to
have in the web reads top-to-bottom, so I don't wanna deal with
inverting coordinates a second time...

Flat text is just *never* what you want.   ---stephen p spackman
